ICE GENERATOR AND ICE GENERATION METHOD Russian patent published in 2012 - IPC F25C1/12 F25C5/18 

FIELD: power industry.

SUBSTANCE: ice generator includes heat exchanger, source water supply system and ice removal device, closed circuit which is formed with source water and generated ice storage tank, supply pipeline, flow pump, heat exchanger, valve and outlet pipe. Expansion tank is connected between pump and heat exchanger, and heat exchanger represents flow housing with cooling agent supply and discharge connection pipes, water supply flange and outlet flange of water mixed with ice crystals. Elastic element the inner surface of which is coated with antiadhesive coating is arranged between flanges. Ice generation method involves water pumping through heat exchanger and removal of the formed ice. Water is supplied from the tank through supply pipeline with a pump to expansion tank and inside elastic element which is located in heat exchanger and washed with cooling agent which is cooled to negative temperature. Cooling agent pressure is set below water pressure in elastic element. When expansion tank is filled, valve is opened and pressure in elastic element is reduced. Ice crystals separated during deformation of elastic element from its inner surface are supplied together with water flow via drain pipe to the tank.

EFFECT: use of this group of inventions allows performing the continuous ice obtaining process at high process efficiency.
