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.

These calculations provide a good indication, but DeLaval does not claim that such results are typical of all farms and results are not warranted or guaranteed. Actual results and improvement will depend on a number of factors, including prior milking practices, type of cows, farm and herd maintenance practices. Calculation is based on following figures: water: milk flow ratio 1:2, 365 days a year, energy consumption to cool 1000l of milk based on real case/external studies (TNO), warm water temp 55C
