EXPERIMENTAL STUDIES OF THE AIR INJECTOR SYSTEM OPERATING MODES OF THE MILK WASHING SYSTEM

Abstract
The use of modern methods of efficient purification of milking machines on livestock farms is an important way of improving the quality of milk, in accordance with the sanitary and hygienic standards of its production. In order to improve the quality of washing, we propose to use an injector that performs the function of periodically supplying air into the volume of the milk line, thereby creating significant variations in vacuum pressure and, consequently, a controlled hydraulic shock, the control of which must be carried out using automated milking systems. As a result of scientific experimental research and production verification of the efficiency of functioning, the goal was achieved − to confirm the adequacy of theoretical prerequisites for the design and optimization of operating modes of the air injector of the milking system flushing milking plant and determine its rational dimensional characteristics. In particular, as a result of experimental studies of the modes of operation of the air injector of the milk-washing system of the milking plant, the dependence of the rate of pressure change and change of the degree of purity of the milk line on the working vacuum pressure, the volume flow rate of air through the air injector, the duration of the injection time of the air injector and the duration of the air injection were established. Thus, as the working vacuum pressure increases, the volume flow rate of the air through the air injector and the duration of the pause of the air injector, the rate of change of pressure increases. Conversely, as the duration of the injection of the air injector increases, the rate of pressure change decreases. Experimental studies were carried out at the experimental stand on the basis of a laboratory milking machine with available upper and lower milk ducts with a flushing apparatus manufactured by OJSC “Bratslav”. 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 obtained the corresponding rational parameters of the modes of operation of the injector. Prospects for further research are the creation of a production sample of an auto-controlled injector that creates vacuum and hydraulic shock.
