Milk Cooling Tanks

Code : MCT

We manufacture a wide range of Milk Cooling Tanks / Bulk Milk Coolers / Milk Chillers both Direct Expansion and Ice Bank type. After the end of milking the good quality of the milk should be preserved by cooling it as fast as possible. To satisfy this requirement Dairy n Pack offers a range of cost effective milk cooling tanks suitable for different size farms.

Direct expansion cooling
This is the most common milk cooling system. The bottom of the tank has been designed as an evaporator, while the heat of the milk goes through the stainless steel wall to the refrigerant. The refrigerant evaporates, which takes the heat away from the milk. Since direct expansion tanks do not have a cold buffer, energy must always be available. In this type of system, the milk is cooled directly and agitated after arrival in the tank.

Ice Bank cooling
In indirect cooling systems, the evaporator is situated in a reservoir filled with the heat carrier, which is mostly water. The evaporator consists of a system of coils or pipes in which the cooling medium evaporates and cools the heat carrier.

The biggest advantage of an ice bank system is that it allows the cooling capacity to be stored in an isolated reservoir with a heat carrier and cold buffer or ice buffer . In areas where there is not sufficient energy, an ice bank system provides an efficient cooling solution. The formation of ice around the pipes in the reservoir forms the cold buffer that can be used for cooling the milk. The cold buffer makes it possible for cooling in areas where energy in peak times is more expensive, or where the use of electricity is limited, and means that the cooling system can be turned off to avoid an energy rush during milking. The production of cold can occur in periods when energy is inexpensive, and can be extended over a longer period, enabling a small compressor to be used.

The energy efficiency of the indirect system is lower than that of the direct system, because cooling of the carrier demands extra energy. The energy consumption of an ice bank cooler is 23 W/l. There are two types of chilled water equipments. The first is the ice builder, which accumulates ice between milking using a small condensing unit that runs up to 18 hours a day. The second is the package chiller, which has a large condensing unit that runs only during milking.
