What kind of equipment is a milk chiller?
It is a kind of refrigeration equipment that cools the freshly squeezed milk from 36°C to 4~5°C in 2~3 hours. It is also one of the equipment used by many dairy companies.
Since the temperature of the milk that has just been squeezed out is relatively high, it is not conducive to preservation, so it is also necessary to use a cold milk chiller to cool down and pasteurization and other technologies for final storage.
What is the cooling method of the milk chiller?
There are two types of direct cooling and indirect cooling. The former uses a refrigerant (refrigerant) to directly exchange heat with the milk through the evaporator, but the structure inside this chiller must be made of food-grade stainless steel.
The latter indirect cooling can use refrigerant to cool the milk through the evaporator to cool the refrigerant (water or brine). That is, tap water can be directly used to enter the chiller for cooling and then pass through the barrier for cold and heat exchange.
How much does a milk chiller cost?
This needs to determine the price according to the actual matching power and cooling capacity. The unit price is high or low. If the power is not large, tens of thousands of yuan can solve the cooling problem. If the power is more than tens of horses and the cooling capacity, the cost will be higher. Ten, 200,000 or even hundreds of thousands of RMB.
What is the difference between the evaporator of the milk chiller and the standard one?
If the direct cooling method is adopted, the evaporator must be made of food-grade stainless steel and be made of reinforced thick wall to prevent fluorine leakage in the later period from affecting the safety and quality of milk. Although the direct cooling effect is good, there are disadvantages in long-term use. It is recommended to use the indirect cooling method. The milk and the water in the interlayer exchange cold and heat, which really serves the purpose of cooling, so that it will not cause food safety hazards to the milk. Dongguan Jiusheng Machinery Co., Ltd. specializes in the production of air-cooled chillers, Water-cooled Chillers, Open Chillers, Screw Chillers, Air-cooled Box Chillers, Water-cooled Box Chillers, etc.
