Precision engineering for rapid milk temperature reduction
Milk is primarily refrigerated to maintain its quality for as long as possible. Reducing the milk’s temperature reduces the growth of bacteria. On-farm milk cooling is more cost efficient when pre-cooling is used. With pre-cooling, well water passes through a heat exchanger before it enters the milk tank for cooling. To maintain maximum quality milk, it is vital that both these cooling stages work efficiently. Optimizing the efficiency of pre-cooling milk before it enters the bulk tank, requires the correct water-to-milk flow rate. We recommend a water-to-milk flow rate of 2.5:1 for our BM range and 2:1 for our BH range.
Pre-cooling reduces the cooling load and thus the energy required. A correctly sized DeLaval plate heat exchanger package can save you up to 60 percent of your refrigeration energy costs.
To meet your farm’s requirements for milk pre-cooling, the DeLaval plate heat exchanger range comprises three sizes for medium milk flow rates and five sizes for higher milk flow rates. With your budget in mind, you can select from the effective DeLaval plate heat exchanger BM 23, 37 or 51 plate options – framed in either aluminum or stainless steel. The DeLaval plate heat exchanger BHSS 23, 35, 47, 61 or 73 plate options for higher milk flow rates – are all supplied with stainless steel frames.
The stainless steel DeLaval plate heat exchanger is a long lasting, non-rusting and easy-to-clean pre-cooling solution. Clip-on gaskets make it easy and quick to service, keeping maintenance costs to a minimum. The effective block and bleed gasket seal design helps ensure your milk does not mix with the cooling water.
