Abstract
This article describes the program and experimental procedure of studies as well as comparisons of a serial milking machine and milking machine with independent vacuum mode; oscillograms and curves of their operations are presented. The experimental studies have been based on the developed partial and appropriate standard procedures as well as State Standards GOST. Optimization of milk ejection from cow udder is proposed using experimental milking machine with independent vacuum based on similarity theory and dimensional analysis in combination with experimental design. Fat content in milk was measured by the Gerber method (sulfuric acid) according to State Standard GOST 5867-95. Milk samples for analysis were taken at start and end of preliminary and final periods as well as each five days of the main period. Mass fraction of proteins in milk was determined by formal titration, and casein content in milk was determined by the Mattiopulo method. Milk density, content of milk solids and content of nonfat milk solids were determined by predictions. Advantages of the milking machine with independent vacuum mode have been highlighted, final results of the performed work have been summarized. The main design and engineering parameters of the experimental milking machine with independent vacuum are as follows: rated vacuum pressure in vacuum line: 48?1 kPa; in teat cup: 30- 33 kPa; ejected milk weight per one operation cycle of actuator: 3.0 g/s….7.0 g/s. Average intensity of milk ejection in experimental group in comparison with reference group increased in average by 9.1%, and fat content in milk increased in average by 0.11%. The experimental milking machine exerts more sparing effect on cow teats, herewith, vacuum load during milking has decreased by 30%, and total milking time has been reduced from 0.7 to 1 min in comparison with ADU-1 serial milking machine.
