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 water-to-milk flow rate to pre-cool the milk before it enters the bulk tank will optimise pre-cooling efficiency. We recommend 2.5:1 or 2:1 water-to-milk flow rate.
DeLaval plate cooler BM
A plate cooler can cut refrigeration energy costs by up to 60% by reducing the cooling load on your bulk tank. DeLaval plate heat exchanger BM features a highly durable, precision-engineered stainless steel frame. It is designed for low to medium milk flow rates. Combined with easy to service clip-on gaskets, this range of stainless steel cooling plates optimizes milk pre-cooling efficiency.
DeLaval plate heat exchanger M6
These plate heat exchangers are especially designed for larger dairies and can reduce your milk cooling energy requirements by as much as 35%. A large cooling surface delivers efficient heat transfer and gentle milk handling. You can choose single or dual coolant systems to meet your specific cooling need
