Annotation

As a result of long-term operation of the milk-conducting lines of milking machines on their internal surfaces various in composition, properties, thickness, strength of adhesion to the deposition surface of alkaline and acidic nature are formed. Their presence leads to bacterial contamination of milk, resulting in a decrease in its quality and shelf life.
The process of washing the elements of milking machines is one of the most important technological operations, the efficiency of which depends on the level of primary contamination of milk.
The purpose is to investigate the operating parameters of the air injector operation of the milkweed flushing system of the milking plant and to substantiate their rational values.
As a result of numerical modeling in the software package STAR-CCM + and experimental studies of the process of washing the milk line of the milking plant using an injector, the dependence of the change in the speed of pressure and the value of the degree of purity of the milk line at different values of its diameter from the working vacuum injection time and injection injection time pauses of the air injector.
Comparing the theoretical and experimental dependences of the Fisher pressure velocity changes, the Pearson correlation coefficient and the determination coefficient can confirm the adequacy of theoretical studies.
Comparing the theoretical and experimental dependence of the degree of purity of the milk line by Fisher's criterion, the Pearson correlation coefficient and the coefficient of determination can confirm the adequacy of theoretical studies.
Solving the compromise problem, which minimizes the value of the rate of change of pressure at the highest value of the degree of purity of the milk line for different values of the diameter of the milk line obtained the corresponding rational parameters of the modes of operation of the injector.

Keywords: milk, milking machine, washing, modes, numerical modeling, experimental studies
