MILKING EQUIPMENT OF " YALYNKA" (“HERRINGBONE”) "EUROCLASS 1200" TYPE TESTING RESULTS

Abstract The purpose of the research is – to evaluate the milking platform of "Yalynka" ("Herringbone") "EuroClass 1200" type manufactured by "GEA" (Germany) for milking cows based on the results of experimental testing. Research methods. During the testing of the milking parlor "Yalynka" "EuroClass 1200" type the quality of the technological process was determined using the methods described in ISO 5707:2007, ISO 6690:2007, DSTU 7435:2013 and DSTU 3662:2018, operational-technological and economic evaluation was carried out according to DSTU 8424:2015 and DSTU 4397:2005, safety and ergonomics of the equipment were determined according to DSTU EN ISO 12100:2014. Research results. According to the results of experimental testing, it was established that the milking parlor "Yalinka" "EuroClass 1200" type of German production at the appropriate level performs the technological process of machine milking of cows. The obtained research results showed that the average total milking time of one cow is 5,07 minutes, the average intensity of milk excretion as a whole during milking – 2,35 kg / min. Milk obtained during milking cows in terms of quality corresponds to the grade "Extra" in accordance with DSTU 3662: 2018. Devices for controlling the process of milking cows "DemaTron 70" and computer herd management system "Dairy Plan C21" perform the technological process of milking cows in automatic mode, control over the implementation of technical parameters of the milking process, milk accounting and shutdown of milking machines. Based on the results of conformity assessment of the construction of the milking parlor "Yalinka" "EuroClass 1200" type in terms of safety and ergonomics, it is established that it meets the requirements of DSTU EN 12100: 2014 and DSTU 60204-1: 2015 for items related to its design, which is the evidence base of its compliance with the Technical Regulations for the Safety of Machinery and the Technical Regulations for Low-Voltage Electrical Equipment. Productivity of the milking installation-platform makes 70 heads / hour. Serves the milking parlor 2 operators of machine milking. Electricity consumption per milking a cow is 0,13 kWh. Annual operating costs are 4247 UAH / head in the conditions of 3 times milking of cows. Conclusions. For the first time in Ukraine, experimental testing of the milking parlor "Yalinka" "EuroClass 1200" type showed that the equipment satisfactorily performs the technological process of machine milking of cows with their loose housing and provides milk of the "Extra" grade. The «Euroclass 1200» «Yalinka» milking parlor is characterized by a high technical level and can be widely used in Ukraine.
