ENERGY-SAVING ACCUMULATION PLANT FOR MILK COOLING IN FARMS USING NATURAL COLD Russian patent published in 2008 - IPC A01J9/04 F25D3/00 

FIELD: agricultural engineering.

SUBSTANCE: energy-saving plant has accumulation reservoir, compression-condensation unit, evaporator placed within accumulation reservoir, regulating valve, milk pump, coolant pump, and control unit. There are openings in accumulation reservoir cover for communicating inner volume of accumulation reservoir with atmosphere through hoses with valves. Air filter and fan are positioned on one of hoses. Two closable drain openings are formed in side wall of accumulation reservoir, above and below upper edge of evaporator: upper drain opening and lower drain opening. Two filters provided in central part of accumulation reservoir, at its opposite sides, are made in the form of vertically mounted flexible perforated hoses. One of said filters oriented downward is connected through coolant pump to inlet of coolant section of heat-exchanger. Other filter oriented upward reaches level of lower drain opening and is connected to outlet of coolant section of heat-exchanger. Inlet of milk section of heat-exchanger is connected through milk pump to accumulation reservoir for milk, and outlet of milk section of heat-exchanger is connected to milk storage reservoir-thermos.

EFFECT: reduced capital and operation expenses and enhanced reliability in operation of cooling system.
