Cooling device for milk

The utility model relates to a milk processing technology, and discloses a cooling device for milk. When the cooling device is used for cooling milk, water in the water storage tank is refrigerated through the heat exchanger and the refrigerator and then enters the cooling water pipe from the water inlet pipe, the refrigerator and the heat exchanger are combined, heat exchange is rapid, the milk cooling time is shortened, the structure is simple, and practicability is high. And after the cooling water pipe is full of water from bottom to top, the water flows into the water storage tank from the water outlet pipe for recycling. When 80% of milk is collected, the milk can be sent into the cooling tank to be cooled, after primary cooling, the milk enters the cooling tank again from the milk circulating pipe to be cooled, rapid cooling is achieved, then the milk is continuously supplemented, and when the milk is cooled to a certain temperature, the milk flows out from the milk outlet pipe. After one cycle of oper
