Vacuum decolorization process is a critical step in edible oil refining, used to remove unwanted pigments, trace metals, and contaminants. When these compounds remain in the edible oil, they can affect the taste, color, and stability of edible oil. But what makes vacuum conditions so crucial for achieving the best edible oil refining results?

Under vacuum, the edible oil decolorization process operates at lower temperatures, which protects the edible oil from oxidation—a common cause of spoilage, off-flavors, and a reduction in shelf life. Unlike traditional methods, edible oil vacuum decolorization preserves the oil’s natural nutrients and enhances its clarity and purity. This means your customers get an edible oil that not only looks clearer but also retains the health benefits they seek.
Besides, edible oil vacuum decolorization process of our Henan Glory Company also provides another significant benefit: it uses less energy. The lowered boiling points achieved under vacuum help minimize thermal stress, reducing energy consumption and keeping the decolorization process sustainable. This commitment to environmental responsibility aligns with our dedication to quality, making our edible oil refining machine the clear choice for customers who value both purity and planet-friendly practices.

In the world of edible oil refining, oil quality is everything. Henan Glory Company adopts advanced edible oil refining process to ensure oils not only meet industry standards but exceed customer expectations for purity, color, and safety. We have three types of edible oil refining machine: batch type, semi-continuous and full-continuous. You can choose them based on your needs.

Oil dewaxing treatment process during edible oil refinery is to remove the wax content in some kinds of crude edible oil, wax is a kind of polymer lipid, high melting point, poor solubility in oil, will affect the taste and transparency of the edible oil, so the edible oil needs dewaxing treatment. However, not all oils need to be dewaxed, which oils need dewaxing treatment?

This process is mainly for those oils that are easy to precipitate wax at low temperatures, such as sunflower oil, rice bran oil, corn embryo oil, cottonseed oil, tea seed oil, etc. When untreated, these oils become cloudy at low temperatures, affecting transparency and taste. Generally speaking, the process of edible oil dewaxing is divided into four steps: heating, cooling, crystallization, filtration.
The Dewaxing Process:

1. Heating

First, the refined edible oil should be heated to 55˚C, which is to make sure that all the crystal in edible oil have been broken. At room temperature, a part of the solid wax in the oil has precipitated crystals. In order to achieve a good dewaxing effect, it is necessary to heat the oil with a steam heater before oil dewaxing treatment process, destroying the existing crystals. This will achieve a better crystallization effect, and this process can also be called crystal breaking.

2. Cooling

The oil is gradually cooled to allow waxes to crystallize. This step requires precise temperature control to optimize crystal formation.

3. Crystallization

At low temperature, the wax will gradually form larger crystalline particles. In order to promote the formation of crystallization, slow cooling and slow mixing can be used, and the crystallization tank is equipped with variable speed mechanical mixing to ensure uniform mixing. When the oil appears as semi-solid stearic crystals in the liquid molasses, prepare for filtration. If crystallization does not work well, the slurry is sent to the feed oil heater for recrystallization.

4. Filtration

When the wax is fully crystallized, the crystallized wax is separated from the oil by filtration. Filtration is usually done using a plate and frame filter.

The extraction of edible oil is a complex process, so the final oil yield of the oil press involves a lot of equipment and raw materials, and each link plays an important role, including the nature of the raw materials, the operating conditions of the equipment and the pre-treatment and post-treatment methods.
Nature of Raw Materials

1、Type of Oil - Bearing Seeds or Fruits

Different oil - bearing materials have inherently different oil contents. For example, sunflower seeds usually have a relatively high oil content compared to some other common seeds. But soybean seeds don't have high oil content. The genetic makeup of these raw materials determines the maximum possible oil that can be extracted from them.
2、The quality of the raw materials

The quality of the raw materials plays a crucial role. High - quality, mature seeds or fruits generally yield more oil. Immature ones may have lower oil content as the oil - forming process within them may not be complete. Damaged or rotten materials can also reduce the oil yield. For instance, if soybeans are affected by mold or pests during storage, their oil - extracting efficiency will be negatively impacted.

Operation Conditions of the Equipment

1、Pressure and Temperature

Most oil presses operate under specific pressure and temperature ranges. Appropriate pressure is essential for squeezing the oil out effectively. If the pressure is too low, not all the oil within the raw materials will be extracted. On the other hand, excessive pressure may cause damage to the oil - containing cells and lead to the formation of impurities that can affect the quality and quantity of the oil. Temperature also has a significant impact. In some cases, a higher temperature can help in reducing the viscosity of the oil, making it easier to flow out during the pressing process. However, extremely high temperatures can cause the oil to oxidize or decompose, thereby reducing the yield.

2、Type and Design of the Oil Press

There are various types of oil presses available, such as screw presses, hydraulic presses, etc. Each type has its own advantages and limitations in terms of oil extraction efficiency. The design of the oil press, including the size and shape of the pressing chamber, the type of screw or piston used, and the overall structure, can affect how well the raw materials are processed and the oil is extracted. For example, a well - designed screw press with an optimized screw profile can ensure better contact between the raw materials and the pressing mechanism, resulting in a higher oil yield. Our company have different capacity screw oil press, if you are interested, please contact with our company.
Pre - and Post - Processing Methods

1、Pre - Treatment of Raw Materials

For sunflower seeds, soybean seeds, peanut seeds and others seeds, thepre - treatment processes like cleaning, drying, and crushing are vital. Cleaning removes any dirt, debris, or foreign substances that could interfere with the oil extraction process. Drying the raw materials to an appropriate moisture content is crucial. If the moisture content is too high, it can cause problems such as clogging the press or reducing the efficiency of oil separation. Crushing the raw materials into smaller particles increases the surface area available for oil extraction. A finer crush can expose more oil - containing cells, facilitating better oil release during pressing. For palm fruits, the sterilizer time is very important, must need to be processed in 48 hours. For palm kernel oil, if your material is palm nut, you must cracker firstly and separate.
2、Post - Processing of the Extracted Oil

After the oil is extracted, proper filtration and separation processes are necessary. If there is incomplete separation of the oil from other by - products or impurities, it can lead to a lower effective yield of pure oil. Additionally, storage conditions of the extracted oil can also impact its quality over time. If stored inappropriately, the oil may oxidize or deteriorate, which indirectly affects the overall success of the oil extraction process in terms of obtaining a high - quality and high - yield final product. The Henan Glory oil & Fats Engineering CO.LTD have the completely filter system include the vibrate screen, oil clarification, plate and frame filter, vacuum dryer system.

To sum up, in order to improve the efficiency of oil pressing and the quality of oil products, it is necessary to strictly control the factors such as pressure, temperature, and pre - and post - processing Methods. In thtion process, the process parameters should be flexibly adjusted according to the actual situation to achieve a better oil output effect.

When it comes to the production of cooking oil, an oil press machine is a key equipment. Different types of oil press machines have different working principles and characteristics to meet various needs and production scales. Now let me share with you the types of oil press machines and their working principles.

Type 1: screw oil press machine

The screw oil press machine utilizes a rotating screw shaft inside the pressing cage to push the oilseeds, simultaneously pressing them into cakes and squeezing out the oil in a continuous process. This type of continuous oil press machine has several advantages. Firstly, it enables continuous production, enhancing production efficiency. Secondly, the screw oil press machine has a large processing capacity, making it suitable for handling a significant amount of oilseeds. Additionally, it exhibits good adaptability to various types of oilseeds. The screw oil press machine also employs friction heating during the pressing process, increasing the temperature and facilitating the release of oil from the oilseeds. Due to the relatively short pressing time and high oil yield, it maximizes the retention of nutritional components in the oilseeds.
Type 2: automatic oil press machine

An automatic oil press machine is also called an automatic temperature control oil press machine. Compared to screw oil press machines, this type of oil press machine uses electric heating coils for heating and controls the temperature automatically. It reduces the preheating time, allowing the oil press machine to start regular production quickly. Moreover, it helps to reduce energy consumption and machine wear, improving overall efficiency. Therefore, the automatic temperature control oil press machine is particularly suitable for small and medium-sized cooking oil processing plants, as it can lower production costs and increase output.
ype 3: oil press machine with filter

The full name of the oil press machine with filter is the fully automatic temperature control vacuum filter integrated oil press machine, which consists of a temperature control system, oil pressing section, and filtering section. This equipment not only possesses automatic temperature control function but also incorporates a crude oil vacuum filter. During the pressing process, the vacuum pump built-in the machine is used to vacuum and filter the pressed oilseeds, achieving more efficient and integrated cooking oil production. When using the fully automatic temperature control vacuum filter integrated oil press machine to press cooking oil, the automatic temperature control system is first activated to reach the appropriate pressing temperature inside the oil press machine. Then, the oilseeds are fed into the pressing chamber for pressing. The obtained cooking oil is subsequently filtered through the filter to remove residues and impurities, resulting in pure cooking oil. The fully automatic temperature control vacuum filter integrated oil press machine is easy to use and highly efficient, providing a convenient solution for cooking oil production.
In summary, different types of oil press machines play important roles in cooking oil production. Whether it's a screw oil press machine, automatic temperature control oil press machine, or fully automatic temperature control vacuum filter integrated oil press machine, they all have their unique characteristics and applicability to meet different needs and production scales.

According to different processing capacity, the soybean oil production line is also different. For small-scale soybean oil mill plant, the main production processes include cooking, pressing and filtering. If the budget is sufficient, a full soybean oil production line can also be used.Now, I will introduce these parts in detail for you.
Cooking machine

The cooking process in a small-scale soybean oil production line is essential.The purpose of cooking is to make changes in the biochemical composition and physical state of the seeds through the action of temperature and moisture, in order to increase the oil yield and improve the quality of oil and cake. Henan Glory's small cookers usually use electric heating or steam heating, which is energy-saving and environmentally friendly. Its automatic control system can monitor the temperature in real time to ensure stable temperature, which not only improves the oil yield of the oil, but also ensures the taste and nutritional content of the oil.
Pressing machine

The oil press is one of the core machine of the small-scale soybean oil production line. The principle of pressing is to use physical pressure to separate the oil directly from the seeds, the whole process without any chemical additives, to ensure that the product is safe, hygienic, pollution-free, and the natural nutrition is not destroyed. Henan Glory supplies three kinds of home use soybean oil pressing machines. The first one is a single screw soybean oil extraction machine, which consists of hopper, gearbox, press chamber, pressing screw and machine frame. The processing capacity of this single screw soybean oil extraction machine is 1-20TPD, which can be selected according to your own needs. The second one is automatic temperature control soybean oil extraction machines. The electric heating coil device is used to quickly heat the soybean oil pressing machine with higher efficiency. The third one is automatic temperature control vacuum filtration all-in-one soybean oil extraction machine. After the soybean oil is extracted, it can be filtered directly without the need for additional sedimentation filtration steps. Our oil presses have been tested many times and are easy to operate with oil yield of over 95%. Secondly, in addition to producing soybean oil, our small edible oil production line oil press can also be used for a variety of raw materials, such as peanuts, sunflower seeds, etc.
Filtering machine

The filter removes these impurities from the crude soybean oil by physical filtration, thereby obtaining clear and pure finished oil. If you use an automatic temperature control vacuum filtration soybean oil extraction machine, you can ignore this step. Or you can choose plate filter, which has a good filtering effect, and it's easy to operate.
If you prefer soybean oil production line, the processing capacity is more but the budget is limited, it is recommended that you consider pretreatment + pressing machines.

Pre-treatment machines mainly include vibrate screens, destone and magnetic separators. They help remove debris, dust, stones and other impurities from soybeans and remove metal particles that may exist in the raw materials. These impurities can damage subsequent machines and also affect the quality of the final soybean oil. Also have the crusher, softener, flaking machine and cooker. Soybeans are relatively hard, so the crusher can break the physical structure of soybeans, which can reduce damage to the oil press and increase the oil yield. The softening pot makes the oil molecules in the soybeans free, so that the soybeans can be in the best state for oil production. The flaking machine increases the contact area of the oil. The cooker adjusts the soybeans to the appropriate temperature and moisture, so that more oil can be produced and the oil quality is better. Then we can press.

If your budget is sufficient, you can consider the machines configuration of pretreatment + solvent extraction. The solvent extraction machines use chemical solvent extraction. The main process is divided into four parts: solvent extraction, mixed oil evaporation and gas stripping, desolventizing roasted meal and solvent recovery.

If you plan to further process this soybean oil, you may consider refining machines. Refining machines mainly include degumming, deacidification, decolorization, deodorization.

The above are small-scale soybean oil production line. If the small-scale soybean oil mill plant has a processing capacity of less than 20 tons, it is recommended to use the above steps. If the processing capacity is large, it is recommended to use more complete soybean oil production machines to obtain more and cleaner soybean oil. Henan Glory provides a variety of soybean oil production machines and can customize a suitable production line for you according to your needs. Contact us now for details!

In the process of cooking oil processing, oil seeds should be pretreated and then pressed to get crude oil. The oil seed pretreatment machines play an important role in the cooking oil processing process, which can improve the oil yield of oil seeds and maximize the benefit of the factory. It's indispensable for large and medium-sized cooking oil manufacturers.
The oil seed pretreatment machines mainly include vibrating screen, magnetic separator, stone removing machine, softening pot, rolling embryo machine, puffing machine, steaming pan, etc. Due to the different features of oil seeds, the selection of oil seeds pretreatment machines in the production process is also different. Take the soybean as an example, because the water content of the soybean is less, the hardness is larger, so it needs to be softened, which greatly reduces the damage to the press, improving the yield of soybean oil.

Oil seeds pretreatment machines also have many important functions, such as:

1. After cleaning and removing impurities by vibrating screen, magnetic separator and stone removing machine, large and small impurities and stones are removed to get cleaner oil seeds, which is convenient for subsequent pressing and improves the quality of wool oil, and reducing the wear of the subsequent machines.

2. The oil seed raw material can also be softened through the pretreatment process, putting the oil seeds in a state more suitable for pressing and increasing the oil yield.

3. Oil seeds pretreatment machines can be used to roll out some of the oil seeds in advance, reduce the residual oil rate of oil seed and improve the production efficiency of the factory.

If you don't know how to choose them, Henan Glory Company will introduce you the the advantages and disadvantages of hydraulic and screw oil pressers, and you can choose suitable oil presser to buy based on your requirement.
1. The the advantages of hydraulic and screw oil pressers
Advantages of hydraulic oil presser:
1) High oil quality: Hydraulic oil presser uses physical way to extract oil, and no heating, and the pressure of the equipment is hydrostatic, and the mechanical friction of the oil is very small, so the oil is very clean and can be consumed directly without any treatment.

2) Suitable for cold pressing: Especially for sesame, peanut, walnut and so on.

3) Environmental protection and energy saving: There is less noise during operating. It is physical pressing without heating, no addition of any chemical substances.

4) Easy to operate and cost less: Suitable for small investors, family use or small scale edible oil extraction production line.

Advantages of screw oil presser:
1) High oil yield rate: The screw oil presser presses the oil by continuously pushing the screw shaft forward and squeezing the material. As the screw oil presser goes through 3-4 times of squeezing, the oil yield is higher than that of a hydraulic oil presser with a single squeeze.

2) Three types and many models can be chosen: Henan Glory Company provide three types of screw oil presser: single screw oil presser, screw oil presser with automatic temperature control system and screw oil presser equipped with vacuum filtration system and automatic temperature control system. Specially, the last one is very popular among the small investors. The oil quality is clear and pure with less foam and impurities after pressing. And they also have different models for different processing capacity.

3) Durable and stable: Because of the simple mechanical structure of the left and right screw presses, it’s more durable and stable.

4) Suitable for pressing different oil seeds: Screw oil presser is reasonably designed with advanced performance and is suitable for various oil seeds pressing, such as soybean, peanut, cottonseed, sunflower seeds and so on.

5) High automation: It can be used singly, also can be used in full continuous edible oil processing line.

2. Disadvantages of hydraulic and screw oil pressers
Disadvantages of hydraulic oil presser:
1) Low oil yield rate: Once pressing, the oil yield rate is high.

2) Low automation and small processing capacity: It can not process large scale capacity and must be operated by workers.

3) Difficult in fixing: Different from screw oil presser, the hydraulic oil presser is a closed hydraulic system, if only part of the leakage of oil will make the whole machine useless.
Disadvantages of screw oil presser:
1) ‌More nutrient loss: The screw oil presser generates more heat during the pressing process, resulting in more nutrient loss of the oil, and is not suitable for pressing high-end oils such as walnuts and peony seeds.

2) ‌More impurities: The oil pressed by the screw oil presser has more impurities and must be finely filtered by a centrifugal oil filter before it can be used, which increases the cost and time of subsequent processing.

3) Complex operation: The operation of the screw oil presser is relatively complex, and it is difficult to learn by yourself. It requires certain technical training to master it.

The above is Henan Glory company's introduction of the advantages and disadvantages of hydraulic and screw oil pressers to make you more aware of their differences and make better choices. We hope that it can be helpful for you. Please feel free to leave a message on our website if you still have any questions.

Sunflower oil is a type of edible oil produced from sunflower seeds, which are rich in unsaturated fatty acids such as linoleic acid and have various nutritional values. Generally, the oil content of whole sunflower seeds is about 45%, and the average density of sunflower oil is about 0.92 kg/L. Therefore, depending on the different oil production methods, the amount of sunflower seeds required to produce one liter of sunflower oil is approximately 2-2.5 kg. Let us analyze it in detail from the different oil production processes of sunflower seeds:

Usually, there are two methods for producing sunflower oil: the physical pressing method of sunflower oil and the solvent extraction method of sunflower oil.
Physical pressing method of sunflower oil

To produce sunflower oil using the physical pressing method of sunflower oil, the oilseeds need to be cleaned, hulled, and separated from the kernel to remove impurities and sunflower seed shells that may affect the oil yield. Then, the sunflower seeds are steamed in a steamer to prepare the oilseeds for pressing. After that, the oilseeds are pressed in an oil press to obtain sunflower oil and oil cake. The actual oil yield using the physical pressing method of sunflower oil is usually about 38-39%, and the residual oil rate in the oil cake is 6-7%. Therefore, the amount of sunflower seeds required to produce one liter of sunflower oil is approximately 2.36-2.42 kg.
If your daily production is between 1-600 tons, it is recommended to use the physical pressing method of sunflower oil. For a daily production of 1-20 tons, a single screw sunflower oil press machine is suitable for small scale customers due to its simple operation. The single screw sunflower oil press machine can not only press sunflower seeds but also peanuts, coconuts, cottonseeds, soybeans, and other oilseeds. However, if your daily production reaches about 20-600 tons, a sunflower oil production line is recommended. The sunflower oil production line usually includes cleaning machines, hulling machines, kernel and shell separating screens, steaming pans, oil presses, and filtering machines.
Solvent extraction method of sunflower oil

To produce sunflower oil using the solvent extraction method of sunflower oil, the sunflower seeds also need to be pretreated, including cleaning, hulling, kernel and shell separating, steaming, to adjust the state and structure of the sunflower seeds and improve the oil extraction efficiency. Then, the sunflower seeds are subjected to pre-pressing to obtain sunflower oil and oil cake. The oil content of the oil cake obtained after pre-pressing is about 15%. After that, the sunflower oil is extracted from the oil cake by solvent extraction method of sunflower oil, and the residual oil rate can be reduced to less than 1%. Therefore, the actual oil yield of sunflower oil using the solvent extraction method of sunflower oil is close to 45%, and the amount of sunflower seeds required to produce one liter of sunflower oil is approximately 2.04 kg.

Our company can provide solvent extraction solutions ranging from 5-5000 tons per day. If you have a large processing volume and pursue higher oil extraction rates, it is recommended to choose edible oil solvent extraction equipment to extract sunflower oil. The residual oil rate of solvent extraction is lower, which can help you save costs and obtain more profits. However, it should be noted that the crude edible oil obtained after solvent extraction method of sunflower oil must be refined before consumption.

In summary, depending on the different oil production methods, the amount of sunflower seeds required to produce one liter of sunflower oil is approximately 2-2.5 kg. Regardless of the oil production method used, Henan Glory Company can provide you with corresponding sunflower seed oil processing equipment and customize projects according to your different requirements. If you want to obtain higher quality sunflower oil, we also have different types of edible oil refining machines for you to choose from.

The deacidification methods of oil refining mainly include physical deacidification and chemical deacidification. General physical deacidification is used by steam distillation, and chemical deacidification is used by alkali refining.‌
（1）Physical deacidification method

·‌Steam distillation deacidification‌: This method uses high-temperature steam to remove free fatty acids in the oil under high temperature and vacuum conditions. This method is suitable for refining low-colloid oils, such as coconut oil and rice bran oil, because these oils have a high acid value. If chemical alkali refining is used for deacidification, it will cause excessive loss of neutral oil‌.

（2）Chemical deacidification method

·‌Alkali refining deacidification‌: This is the most commonly used chemical deacidification method. The caustic soda solution is used to neutralize the free fatty acids in the crude oil to generate sodium soap that precipitates in the oil and then separates from the oil. This method can remove most of the free fatty acids, and the generated sodium soap has a good adsorption effect, which can adsorb and remove other impurities in the oil, such as pigments, phospholipids, etc.

（3）Advantages and disadvantages of different methods

·‌Physical deacidification‌: The advantages are simple operation and no wastewater discharge, which is suitable for refining low-colloid oils. The disadvantage is that the deacidification effect may not be as thorough as the chemical method.

·‌Chemical deacidification‌: The advantage is that the deacidification effect is good and most of the free fatty acids and other impurities can be removed. The disadvantage is that it may cause the loss of some neutral oils and may lead to the loss of some nutrients‌.
（4）Application scenarios and scope of application：

·‌Physical deacidification‌: Suitable for low-colloid oil refining, such as coconut oil, rice bran oil, etc.

·‌Chemical deacidification‌: Suitable for most oil refining, especially for scenarios where free fatty acids need to be removed efficiently‌.

By combining different deacidification methods, oil mills can choose the most suitable process according to specific needs to achieve the best refining effect and economic benefits.

Sunflower seed oil is a nutritious, easily digestible and cholesterol-free vegetable oil that is becoming increasingly popular. However, to produce high-quality sunflower seed oil, a certain making process needs to be followed. Below, I will introduce the steps involved in the process of sunflower oil making.
Selection of raw materials

The quality of sunflower seed oil is influenced by the raw materials used. Therefore, fresh, mold-free, odorless and evenly colored sunflower seeds should be selected to ensure the oil yield and quality of the oil. Generally, the oil yield of sunflower seed oil ranges from 30-50%.

Cleaning

After selecting the raw materials, the sunflower seeds need to be cleaned to remove impurities such as soil, stones, and iron. These impurities can reduce the oil yield and quality and cause damage to the equipment. The cleaning process typically involves using vibration screens, magnetic separators, and destoners, achieving a removal rate of up to 99%.
Cracking

Sunflower seeds need to be cracked before pressing. At this stage, a sheller is needed to remove the hull. The presence of hulls can absorb oil and affect the oil yield. For production lines with a daily output of over 100 tons, it is recommended to use a crushing machine directly. Separating the kernel and shell can increase the oil yield.

Kernel shell separation

After cracking, the sunflower seeds and shells need to be separated. It is best to use wind power for separation, which ensures a high dehulling rate without affecting the sunflower seeds.

Flaking

As sunflower seeds are small, we use a flaking machine to flatten them and increase the pressing area and oil yield. The flaking machine must have enough pressure and an appropriate pressing head to ensure uniform flakes are produced.
Steaming and roasting

The hulled sunflower seeds are conveyed to a steamer-roaster to adjust the temperature and humidity of the oil. The optimal pressing temperature for sunflower seeds is about 100°C, with a water content of around 12%. In the steaming and roasting process, it is necessary to control the temperature, time, and humidity to increase the oil yield and quality.

Pressing

The steamed and roasted sunflower seeds are transported to an oil press for pressing. Generally, screw presses are used for sunflower seed oil production. Different brands of oil presses have different oil yields, typically ranging from 84-94%. Our company's sunflower seed pressing machine adopts a specialized design, achieving an oil yield as high as 94%.

Filtration and storage

After pressing, the sunflower seed oil may contain small amounts of residue. Therefore, the oil needs to be filtered using a filter. The filtered crude oil can then be transported to a storage tank for storage.
Of course, different sunflower seed processing volumes require different equipment. If you would like to learn more about the process of sunflower oil making and sunflower oil making machines, please contact us.

Cooking oil machine is very popular now. Many customers of Henan Doing asked the price directly. Actually there are many factors that affect the price. Both the size and strength of the machine manufacturer and the production process of core components can affect the price.

[The First Factor Affecting the Price of cooking oil machine]: The size and strength of the machine manufacturer

The quality of cooking oil machine produced by different cooking oil machine manufacturers is different. Because the strength of small workshops and large manufacturers is very different. The manufacturer is large in scale and the factory was established early, so the cost invested by the manufacturer is greater. In addition, the formal cooking oil machine factory has professional technicians and many patented cooking oil machine technologies, which are incomparable with other small cooking oil machine factories. Therefore, the cooking oil machine looks very simple and the appearance is the same, but the internal quality is very different. Actually, the difference between direct sales of manufacturers and agents looking for factories is also very large. Therefore, before asking about the price, you had better first investigate the scale and strength of the cooking oil machine manufacturer.

[The Second Factor Affecting the Price of cooking oil machine]: The Production Process of Core Components

The core components of cooking oil machine are made by what process, which directly affects the quality of cooking oil machine. If you don't come to the factory for inspection, you may not know that many small cooking oil machine workshops still use very backward manual hammering and polishing methods to manufacture cooking oil machine. You probably can't use a cooking oil machine made under these conditions with confidence.

Cold pressed groundnut oil and refined groundnut oil are quite different in terms of production process, processing machine, and oil quality. As one of the common cooking oils, groundnut oil has clear color, tangy aroma, and delicious taste. It is a relatively easy-to-digest cooking oil and is popular all over the world.

In the production of groundnut oil, some customers choose cold pressing, and some customers choose to further refine the cold pressed groundnut oil, so what is the specific difference between cold pressed groundnut oil and refined groundnut oil? Let's find out.

1. Difference in production process

Cold pressed groundnut oil needs to be processed at a temperature below 60 degrees Celsius. It is a green production technology, but the oil yield is low. The production process is as follows: the groundnut is passed through the cleaning machine to obtain clean groundnut seeds, then the groundnut seeds are crushed and flaked, and the obtained groundnut flakes are put into a roaster for cooking, and finally pressed and filtered to obtain crude groundnut oil and groundnut cakes.

Refined groundnut oil refers to the deep processing of crude groundnut oil to remove harmful impurities in the crude groundnut oil, so as to obtain refined groundnut oil that meets the national quality standards, and then sell it in the market. The refining process is the process of degumming, deacidifying, decolorizing and deodorizing under high temperature and high pressure.

2. Differences in processing machine

For cold pressed groundnut oil, if your budget is low and processing capacity is small, you can choose groundnut oil press or roaster, oil press, filter, etc. If your budget is sufficient and the processing capacity is large, it is recommended that you equip a sheller, vibrating screen, magnetic separator, crusher, flaking machine, roaster, oil press, filter and other equipment.（Related reading: Peanut oil processing plant）

For refined groundnut oil, the main equipment includes degumming tank, deacidification tank, decolorization tank, deodorization tank, heat conduction oil furnace, vacuum pump, leaf filter and other equipment.

3. Difference in oil quality

Cold pressed groundnut oil and refined groundnut oil.jpgCold pressed groundnut oil and refined groundnut oil

The groundnut oil obtained by cold pressing is crude groundnut oil. During the cold pressing process, the nutrients and active ingredients are completely preserved, and the protein content is high. The flavor of the cold pressed groundnut oil is also very popular. But some impurities in groundnut oil could not be removed.


Refined groundnut oil will destroy the protein structure, and the nutrition and flavor are not as good as cold-pressed groundnut oil, but the harmful impurities in the groundnut oil are removed through refining, and the color and storage stability of the oil are effectively improved.

Overall, there are pros and cons to both cold pressed and refined groundnut oils. We just need to choose the one that meets our requirements. If you want to know more about groundnut oil processing machine, or want to invest in groundnut oil production business, please feel free to contact us.

There are two vegetable oil production processes, vegetable oil production process using pressing method and vegetable oil production process using solvent extraction method. Most small and medium-sized manufacturers use the pressing process, while large-scale manufacturers can opt for solvent extraction. The best vegetable oil production process is the one that meets the customers' requirements. As each customer's circumstances are different, their desired vegetable oil production processes and equipment may also vary. Only a personalized process that aligns with the customers' needs can be considered the best. To achieve this objective, we provide professional customized services to ensure optimal adaptability and quality.

Vegetable oil production process using pressing method

For the processing and production of vegetable oil, most manufacturers use a vegetable oil production process using pressing method. Firstly, because the production of vegetable oil is not as large-scale as the production of popular oils, and it is a niche. Most of the investment in vegetable oil production lines is in small and medium-sized vegetable oil processing enterprises. A complete vegetable oil production line requires vibrating screen, de-stoner, magnetic separator, flaking machine and other equipment. There are many models of vegetable oil pressing production lines, which can be customized according to production, budget and other needs, saving equipment investment. Secondly, the vegetable oil production process using pressing method uses the principle of physical extrusion to squeeze oil out of fat, which fully preserves the nutritional taste of vegetable oil and it is becoming more popular with consumers.

Vegetable oil production process using solvent extraction method

Large scale vegetable oil processing plants can use the vegetable oil production process using solvent extraction method to produce vegetable oil. The vegetable oil production process using solvent extraction method uses the principle of solvent extraction to ensure full contact between the oil and the solvent in the extraction device, extract the oil, and then remove the solvent by evaporation to obtain leached vegetable oil. Solvent extraction generally consists of four systems: solvent extraction system, wet meal DTDC system, mixed oil treatment system, and solvent recovery system.

The vegetable oil production process using solvent extraction method has the advantages of high automation, large processing power, high oil yield and low labor intensity. It is an internationally recognized advanced technology for processing grease. After vegetable oil solvent extraction, the oil content in the meal is less than 1%, so that more vegetable oil can be obtained and vegetable oil loss can be reduced. However, the quality of crude oil is not as good as that of pressed crude oil. It must be refined using vegetable oil refining equipment to remove impurities and solvent residues before it can be eaten.

The vegetable oil production process using solvent extraction method can be divided into two types: direct solvent extraction and pre-pressed solvent extraction. Oils with a high oil content, such as sunflower, flaxseed, can be obtained by pre-pressed solvent extraction, which can not only produce pressed crude oil with better nutritional and flavor retention, but also improve oil yield and improve efficiency.

The vegetable oil production process is currently very developed. If you need vegetable oil production equipment, you must consider the quality, safety and technology of vegetable oil production equipment. Henan Glory Company has been established for 12 years and has a professional technical team and our own processing factory, which can provide professional customized services. The specific needs are to configure customized solutions that can meet the needs of each customer based on their actual situation. If you have any needs, please feel free to contact us.

The oil content of soybeans is about 18%-22%, and its oil content is lower than that of peanuts and sunflower seeds. So in the soybean oil production process, how can we improve the oil yield of soybean oil? Henan Glory will give you advice in terms of raw materials, process flow and equipment.

1. Ensure the quality of raw materials

If we want to improve the oil yield, we need to ensure the quality of soybean raw materials. For the soybeans used to extract oil, it is best to choose the ones with full grains, no mold, and no damage. In this way, on the one hand, the oil yield rate is increased, and on the other hand, soybeans in good condition can make our oil quality higher.

2. Adequate pretreatment of raw materials

First, use vibrating screens, magnetic separators, stone removers and other celaning equipment to remove stones, iron nails and other impurities in the raw materials. The purpose of cleaning is to prevent these impurities from damaging the machine and improve the oil yield. Then, the soybeans are very hard, we use the crusher equipment to turn the soybeans into uniform granules, which is beneficial to the later operation process. The purpose of the cooker is to adjust the temperature and moisture of the raw materials to ensure that the raw materials are in the best state for oil production. Finally, according to the need, we can choose to add a flaking machine to roll the raw materials into thin sheets and increase the contact area. Before the raw material enters the oil press, it is very effective for us to improve the oil yield after going through these sufficient pretreatment process.

3. Choose the appropriate soybean oil production equipment

Soybean oil production equipment is directly related to the oil yield and quality of our crude oil, so we need to choose suitable and high-quality equipment to help us extract soybean oil. Henan Glory Company can provide you with customized solutions according to your requirements. If your capacity is relatively small, you can directly use the screw oil press after pretreatment. This oil press has been updated many times, and the residual oil rate is very low, about 6%. If your capacity is relatively large, you can choose the method of solvent extraction to extract oil. The residual oil rate of our soybean oil solvent extraction equipment can reach 1%, which can extract the oil in soybean to the maximum extent.

The above are the methods to improve the yield of soybean oil. If you are interested in soybean oil business or soybean oil production equipment, and want to know more information, please feel free to contact us.
