Purpose and Types of Milk SeparatorsModern technology of dairy production provides extensive use of various separators. These units allow you to clean up the milk from the solids and divide it into fractions with mixed density without changing the chemical structure of substances in its composition.


Separation is carried out by the centrifugal force produced by the machine. Consequently the particles whose specific gravity is greater are dropped to its sides. The higher the speed of milk flow in the reservoir, the more efficient the process of separating milk in the light and heavy fraction.


Typically, a dairy production involves several types of separators, which have individual purpose, a specific design and technological features. However, virtually all these devices are not complicated to use, comfortable to operate and manage.


Classification of separators by manufacturability


Currently, the production of dairy products uses such separators, as


• Milk cleansers;
Cream separators;
• Apparatus for dewatering of cheesecake clot;
• Normalizers,
• Devices for acquisition of high fat cream.


Milk cleansers eliminate milk from unwanted impurities. Cream separators divide the fat fraction of milk. Separators for dewatering of cheesecake clot let to get cottage cheese by rennet method. The use of such devices provides the manufacturing of various fat cottage cheeses.


Normalizers perform the function of the fat content corrector of milk to the desired level. To reduce this parameter is used skim milk, for a larger applied the cream. In addition, the production of dairy products of some kind, such as oil, is impossible without a separation apparatus for the high fat cream.

Classification of separators by design features

In open separators all the ingredients come in contact with air, as supply of milk is open and the yield of the final dairy products takes place without pressure.


In semi-closed apparatus supply of milk is also open, but received dairy products have no contact with air. Reason - its way out under the pressure.


Sealed separators differ by full isolation of different dairy ingredients from the air at the time of treatment. In these devices whole milk, cream and skim milk are under pressure, which is formed at the expense of the separator or a special pump.


Classification of separators by way of sediment and impurities extraction


In the process of milk separator work a variety of precipitation or impurities are collected in its tank. It should to be removed by one way or another. In periodic apparatus drums are dismantled and thoroughly wash.

In the pulsating separators drums are disclosed and automatically cleared. For devices with a continuous discharge used removal of sludge through the nozzles located in the walls of the drum.
