Improved methods of sanitary treatment of milk delivery lines

The article contains the results of research work aimed at improving the technological process of treatment of internal surfaces of milk hoses for pumping milk from a milking parlor to a cooling tank and from a cooling tank to a milk truck. The research has shown that milk hoses for pumping milk to the cooling tank made of different-type materials are contaminated by microorganisms to varying degrees. It has been established that as their service life increases, the content of microbial cells on the surface in contact with milk increases. At the same time, the level of contamination of the delivery hose subjected to mechanical cleaning by a transformable system during the whole research period was 1.8 times lower than that of the hose treated by the traditional method. The improved technological process of treatment of delivery lines in contact with milk ensures a high sanitary and hygienic level of the milk delivery system.
