There are two methods to produce edible vegetable oil, press method and OIL EXTRACTION MACHINE method, the direct pressing method is suitable to high oil yield oil seed, such as sunflower seed, peanut, etc.. But for the low oil yield oil seed material, for example soybean, we need use Oil Extraction Machine, in oder to extract more oils from the low oil yield material.
Depend on the difference of pretreatment process, the Oil Extraction Machine process can be divided into once extracting method, prepress extracting method and extrusion expansion extracting method, can also be in accordance with the extractor type and feature divided into pot groups leaching, rotocel, loop type extraction and so on. But the extraction process is the same.These technological processes generally include four processes: extracting process, mixed oil treatment, wet meal process and the solvent recovery. However, the difference of the Oil Extraction Machine and process conditions resulting in the difference of production effect. Therefore, to achieve a good production effect, we need to study the production technology deeply, the influence of various factors on the extracting process and the relationship between them.
1.The Oil Extraction Machine is part of vegetable oil processing plant which is designed to extract oil directly from oil seed containing less than 20% oil like soybean after flaking.
Rotating  extractor adopts fixed stainless steel grid that is compact and easy to maintain and operate. It is widely used in pre-pressing extraction for high oil-content oilseed, and direct extraction for low oil-content oilseed.
3.The chain drive equipped with motor of low power, the speed can be adjusted easily. when Oil Extraction Machine working, it can be 
controlled effectively. Misella circle system can reduce the residual oil of meal and increase the concentration of miscella.
4.The basic principle is counter-fluid extraction.This Oil Extraction Machine greatly reduces the residual oil of meal and increases the concentration of miscella.
Oil Extraction Machine is the most important section in the edible oil processing line, It is the key point to ensure the quality of edible oil and the meal, and to reducing the production costs. When extracting the oil seeds meal, can choose to use atmospheric pressure or negative pressure evaporation, stripping process, prepress the high oil content oil seeds or directly extracting the low oil content material. The selection of Oil Extraction Machine adopts fixed grid plate rotocel and intermittent siphon large spray, ensure the residual oil in meal below 1%.

Edible oil extraction machine is used for the purpose of extracting oil from many food and non-edible oil seeds. Due to its quality, efficiency and its price, it is quite reasonable, this product is highly demanded in the market. Manufactured by using quality raw materials and many advanced machinery, the product is highly robust, corrosion-resistant and durable body.

Goyum screw press offer oil expeller machines with outstanding features and reliability for full pressing to produce full press cake and crude oil from a wide variety of oil bearing seeds. Available in multiple sizes, depending on your processing capacity, the Goyum extraction machines produces high quality oil and cake with residual oils among the lowest in the industry when using the single pressing process. The Goyum Screw Press can also be supplied for prepressing oilseeds to produce prepress cake prior to solvent extraction.
