Cooling, storage & testing

DeLaval plate coolers and water distribution
Milk is refrigerated to maintain its quality for as long as possible, and to reduce the growth of bacteria. You can achieve more cost-efficiency in on-farm milk cooling if the milk is pre-cooled – using well water through a heat exchanger – before it enters the milk tank for cooling by refrigeration. Both these cooling stages must work efficiently to maintain maximum milk quality. Making sure you have the correct waterto- milk flow rate to pre-cool the milk before it enters the bulk tank will optimize pre-cooling efficiency. We recommend 1.5:1 or 1:1 water-tomilk flow rate.
