HEATING-REFRIGERATING UNIT FOR FARMS Russian patent published in 2003 - IPC

FIELD: agricultural production and food-processing industry. SUBSTANCE: heating-refrigerating unit has two-section heat-exchanger with milk and cold-carrier channels, and hermetically sealed reservoir divided into sections by two group of alternating partitions. First group of partitions are mounted for forming through flow openings above lower edge. Second group of partitions have openings arranged below lower edge. Upper part of outer section defined by partition of second group of partitions is connected to water supply system and to cold-carrier channel inlet of heat-exchanger first section. Lower part of opposite outer section of reservoir is connected to cold-carrier channel outlet of heat-exchanger first section with warm water consumers and through heat level finishing device with warm water consumers for consuming warm water of different temperature levels. Cold-carrier channel of second heat-exchanger section is connected to natural cold receivers-accumulators and water-cooling finishing device. Level sensors mounted in releaser, milk and cold-carrier pumps and temperature sensors are electrically connected to control unit. Heating-refrigerating unit may be used in animal milk farms and at milk processing enterprises. EFFECT: reduced production and maintenance costs and increased efficiency in heat recovery. 1 dwg
