Title: Ice producing apparatus

Abstract: An ice producing apparatus characterized by a refrigerant compresser, a condensor coil, a receiver tank, a solenoid valve, an evaporator, a water spray system and an endless ice grid positioned to traverse the evaporator, which in combination operates to permit a gaseous refrigerant to vaporize in the evaporator, condense in the condensor, collect in the receiver and selectively flow back into the evaporator through the solenoid valve to facilitate freezing of ice in the endless belt ice grid and collecting the ice. The grid selectively moves adjacent to and beneath the evaporator during the harvesting cycle, and collects ice from water which is sprayed on the underside of the grid and against the evaporator during the apparatus freezing cycle. Ice is selectively removed from the ice grid in the harvesting cycle when warm refrigerant is permitted to flow from the receiver tank into the evaporator by automatic operation of a timer and a cooperating solenoid valve.
