Dairy products are considered an integral part of any person’s ration today. Milk is used for making cream, kefir, baked milk, cottage cheese, cheese and a lot of other products. How is milk processed? Production of sour cream, cottage cheese and butter usually requires separation of cream (fat) from milk. Previously, this was done through settling, or as they call it, the gravity method. Milk is put in a cool place and within 24 hours the water comes down while the lighter fat (cream) rises up. Today, this method is still used but it has certain disadvantages. First, it takes time.

The milk can turn sour and the cream will be spoiled. Second, the milk must be poured into large reservoirs that take a good deal of space. Third, the quality of such products is not very high since yesterday’s cream are suitable only for production of home-made butter.

One of the key moments in separation of milk was the invention of special equipment that allows you to do it much faster, better and the products got are more fresh and tasty. A cream separator is an apparatus which lets processing of milk be performed within a few minutes. Milk separators are used not only on large production lines but also in small agricultural farms. You can use separators at home as well. These machines can process 50-80 liters of milk per hour.

Milk separation in home machines is based on the centrifugal and centripetal force. Milk is poured into the bowl rotating at a high speed and, as a result, the lighter fat collects in the middle and the heavier part is pulled outward against the walls of the separator. Next, the cream flows down into another reservoir while the skimmed milk drains off and can be used in making fat-free cottage cheese. It is noticeable that the separators equipped with butter churns provide formation of buttermilk (fat-free cream) in the process of churning. These products are in great demand, especially among the women for whom dietetic nutrition is a part of their life style. These products are also used for feeding young animals. Thus, we can see that separators provide waste-free production of milk.
