IMPROVEMENT OF TECHNOLOGICAL PROCESS OF MILK PRIMARY PURIFICATION

Abstract

Results of research carried out in the conditions of milk production at the dairy complex “Berezovitsa” of RUE “ZhodinoAgroPlemElita” of Smolevichi district in Minsk region are presented in the paper. The research object was the automated milking plant “Parallel” 2×17 (“WestfaliaSurge”, Germany), the subject was the method of milk cleaning of mechanical impurities at vertical arrangement of the filtering device, and milk quality. The technological process of primary treatment (purification) of milk from mechanical impurities has been improved, consisting in the use of a vertical filtration method with new samples of filter elements manufactured by Polymer LLC (Gomel, Republic of Belarus) made of fibrous-porous nonwoven material by pneumo-extrusion method with optimal length of the tubular filter cloth of 20 centimeters. Also composition, technological and sanitary-and-hygienic parameters of milk has been studied, which passed the stage of purification by an improved filtration method when milking cows at automated milking plant “Parallel” 2×17 (“WestfaliaSurge”, Germany) into a short milk pipe.
