Pieno melžimo proceso energetinių sąnaudų tyrimas

Abstract

Unstable milk market, low raw material purchase prices, encourages farmers to look for to reduce the cost of milk production, which depends on electricity prices and the quantities To reduce electricity consumption farmers started to use energy saving technologies. One of is the vacuum pump control with frequency converter. It automatically changes the pump r spedd, in order to maintain a uniform and accurate vacuum level at the lowest power consump The aim of this study is to identify the dairy milking process requires energy consumj The tasks of research are to create the system of vacuum pump-frequency converter electric p dependence on pump power engine speed also measure electricity consumption of dairy mi process with a frequency converter and without it. Experimental results shown, that system vacuum pump-frequency converter electric p dependence on pump power engine speed describes a linear equation: P = 0,0022n - 0,1245 w - electric power, n - pump motor speed. Research of dairy milking process electricity consum shown that vacuum pump without frequency converter use 41,02±0,28 Wh for 1 litre of mil! 7,63±0,12 Wh with frequency converter. In this way accessible from 81.2 to 81.6 perce electricity saving.
