METHOD OF PRODUCTION OF ICE Russian patent published in 1996 - IPC

FIELD: refrigerating engineering; ice generators and heat accumulators of refrigerating plants. SUBSTANCE: evaporating elements are placed in hermetic envelopes made of synthetic films which are then evacuated. Then layer of ice is frozen on evaporating elements to required thickness, after which evacuation is discontinued and atmospheric air is admitted inside envelopes. As a result, synthetic film is separated from metal surface of evaporating elements and solid mass of ice is separated from surface of synthetic film. EFFECT: enhanced efficiency. 2 dwg
