How we fast cool the fresh milk in short time
1. The milking machine extrudates fresh milk through the milk collecting tank by the milk pump into the cache tank, the cache tank is equipped with a liquid level sensor, the sensing data is transmitted to the central processor of the electric control box, after calculation, it is sent to the controller, the controller outputs a signal to control the start and stop of the milk pump.
2, milk pump the milk cache tank is transported to the tubular heat exchanger and refrigerant for heat exchange, tubular heat exchanger is divided into two levels, the first level by groundwater milk from 35℃ to about 20℃ cooling, the second level with refrigerant and milk heat exchange directly, from about 20℃ cooling to below 4℃.
3. The milk temperature is measured by the temperature sensor on the system pipe, and calculated by the intelligent analysis system, which is sent to the frequency conversion controller of the conveying pump. The frequency conversion controller adjusts the speed of the conveying pump to control the flow of milk by changing the power frequency, so as to ensure that the milk temperature is always within the range of cooling requirements.
4. The cooled milk can be directly transported to the milk storage tank.
