UNIT FOR FREEZING ICE IN ICE ACCUMULATOR Russian patent published in 1994 - IPC

FIELD: agriculture. SUBSTANCE: unit has heat-insulated reservoir, tube-conducting system, water pump, level detector, rectifier, control unit. Electrodes are introduced into the unit additionally, made in form of two pairs of plates. One plate is formed by continuous electro-conducting plates, and the other one is made in form of alternating conducting and insulated parts. Moreover, conducting parts of one electrode are disposed at the level of central part of insulated parts of the other electrode. Electrodes are connected to comparison unit, which is connected with control unit through rectifier and amplifier. Inputs of control unit are connected with lower and higher levels detectors, disposed in worked part of ice accumulator. The first output of control unit is connected with electromagnetic rectifier, which is controlled at a distance. The other output of the control unit is connected with water pump through controllable electric drive. Water pump is disposed in heat-isolated worked part of ice accumulator, which is connected with electromagnetic rectifier through feed pipe. Electromagnetic rectifier is connected with water sprayer through air valve. EFFECT: improved efficiency. 3 cl, 1 dwg
