By using an average ratio of two and a half parts water to one part milk, it is possible to reduce the temperature of the milk to within 2 degrees centigrade of the water-input temperature. 

Single stage Plate coolers use one water temperature to reduce the milks temperature,while a two stage plate cooler uses standard water temperature to reduce the milk down then chilled water to reduce it even further.

Using the correct Cooling outfit, a two stage cooler , Mdrive milk pump controller and FloStar milk pump, it is possible to reduce milk temperature down to 4 degrees before entering the tank.
