In Russia, in 2010 a food security Doctrine was adopted, according to which “food security of the Russian Federation is one of the main directions of ensuring national security of the country”. Today the only point of Doctrine, according to which food security is not provided, is milk and dairy products. Our production covers about 65−70 % needs, 10 % below the target. Very important is also the loss of milk during its production. With an annual milk production of about 30 million tons of milk the production does not exceed 65 % and in private farms – 34 %. The relevance of the research problem is due to the lack of domestic equipment for high efficiency clean-up of milk directly on the sites of production. The purpose of this article is to describe the key sources and causes of quality loss of milk. The developments of scientists of the Stavropol Agrarian University for a two-stage cleaning of the milk in terms of dairy farms and complexes are given. Productions testing of prototypes of these devices have confirmed their effectiveness. A distinctive feature of the developed filter is the pre-treatment of milk from large mechanical inclusions in the collection of them in the sump tank and its fine purification by means of filtration, when passing through the filter element. The filter design is protected by the patent. Production test of the filter showed that it provides the cleaning efficiency of milk from mechanical impurities up to a level sufficient to obtain products of the first group of purity according to the requirements of GOST, The article will be useful to scientists and engineers involved in the development of equipment for primary processing of milk on farms and complexes, as well as dairy plants.
