Working principle of milk direct cooling fast cooling equipment：Equipment adopts screw type compressor and water cooling/Organic combination of the air-cooled cooling system，Milk discharge temperature from the milking room is 35℃，Cool down through the direct cold casing type heat exchanger，Milk from 35℃ through the heat exchanger (medium freon, with high heat exchange efficiency),The milk can be instantly reduced to 0-4℃ into the milk storage warehouse or milk truck storage。Fast cooling equipment can reduce the fresh milk from 35℃ to 3℃ temperature in only a few tens of seconds，Can inhibit the growth of bacteria in time，This indicator is an important factor to ensure that the level of fresh milk content is increased。
