There are a number of different types of Milk Cooling Tank available today. The types include those with direct expansion cooling, in-line pre-cooling, and Variable-speed pumps. Direct expansion cooling tanks use pipes that are welded to the exterior of the milk chamber. The rest of the milk cooling tank is covered in insulation and has a metal shell. Here's a closer look at some of the most popular varieties:
Direct expansion cooling
In milk cooling, direct expansion is the most effective method for the milk to cool faster than ice bank tanks. The evaporator forms an outer skin of the inner tank, reducing the need for ice jackets and saving space. These tanks also allow for a greater storage volume than ice bank tanks. The most common form of direct expansion cooling for milk cooling tanks is the Packo direct expansion system. It utilizes a stainless steel evaporator and is the most energy efficient of all the refrigeration methods.
The disadvantage of direct expansion cooling is that it is not suitable for use when the tank is empty or the walls freeze. It can only operate when warm milk enters it, and slow cooling is needed to maintain a low storage temperature. In order to run direct expansion cooling during milking, large refrigeration compressors or condenser radiators are required. Large farms with three-phase power are better suited for this method.
In-line pre-cooling
In-line pre-cooling is important for a number of reasons, including energy efficiency. The temperatures in milk cooling tanks are high enough to cause bacteria to grow, and milk that has been stored for 72 hours can have a drastically different bacterial count than milk that has been stored for only a few hours. A DP pre-cooling system reduces energy consumption while maintaining good microbiological quality.
Modern milk cooling tanks feature alarms and monitoring systems that monitor temperature inside the tank. Moreover, the systems measure temperature of cleaning water, agitator performance, and milk volume. They also record temperature over a specific period. A variety of options are available depending on the type of milk you produce and the time between milk collection and processing. The tank capacity should be suitable for your herd size and calving frequency. It must also meet standards for insulation, energy efficiency, and water consumption.
7" milk inlet hole
This Milk Cooling Tank has a unique design for milk cooling. It has a sloped bottom that facilitates complete emptying and includes a safety feature that stops the agitator when the lid is raised. It features a 7" milk inlet hole, which allows for a strainer to be inserted while adding milk. The temperature inside the tank remains constant to prevent bacteria growth. A 7" milk inlet hole also allows for accurate measurement of milk quantity.
Variable-speed milk pumps
In dairy farms, a milk pump with a variable-speed drive can optimize the flow rate. The speed of the milk pump ramps up and down to match the milk level in the receiving can. The iNTELFLOW can be customized to meet individual requirements, with separate settings for milk and wash. A pump with variable-speed drive can ramp up and down quickly during the wash cycle to ensure that milk levels are regulated to maintain the highest possible quality.
The main benefits of using a variable-speed milk pump are its energy efficiency and low initial cost. It also minimizes the noise and maintenance costs. Another advantage of using a pump with variable-speed technology is that it can maximize precooling with an in-line cooler. It can also save a significant amount of money, depending on the size of the herd, the number of compressors, and the type of Freon used in the pump.
Energy-saving design
A milk cooling system is an important part of a dairy farm's production process. Typically, a cooling system uses a large amount of electricity to cool milk. The energy needed for this process is relatively high, so energy-saving design is essential to a dairy's bottom line. The efficiency of milk cooling systems is measured in Coefficient of Performance (CoP), which is the ratio of the energy required to cool the milk to the useful cooling energy achieved. A good CoP ranges from 1.5 to 3.5. Older systems will have a lower CoP.
One of the most energy-efficient ways to cool milk is a direct expansion tank. These are designed to be robust and energy-saving, and they are available in 13 different sizes. A direct expansion tank can store more milk than a traditional ice bank tank, and it doesn't require a separate ice jacket. Because they have fewer heat transfer processes, these tanks can provide faster cooling. And, they are less expensive than ice-bank tanks.
