Working Principle of Commercial Automatic Ice Making Machine

1. The frozen water pump of the water storage tank circulates continuously through the plate or grid evaporator.

2. After the compressor runs, it is absorbed and vaporized by suction-compression-exhaust-condensation (liquefaction) -throttling and then evaporated at low temperature from - 10 to - 18 degrees in the evaporator. The frozen water continuously condenses into ice on the surface of the cooler evaporator at the water temperature of 0 degrees. When the ice layer condenses to a certain thickness, the evaporation temperature of refrigerant reaches the set temperature of temperature control, that is to say, the defrosting solenoid valve is usually connected to the form of heat pump to defrost, and then realize the next cycle.

Cycle of automatic ice maker:

Through the supplementary water valve, the water automatically enters a water storage tank, and then is pumped through the flow control valve to the diversion head, where the water sprays evenly to the surface of the ice maker, flows like a curtain over the wall of the ice maker, and the water is cooled to the freezing point, while the water that has not been evaporated and frozen will flow into the water storage tank through the porous groove and start recycling again.

Ice mining cycle:

When the ice reaches the required thickness (the thickness can be chosen by the operator/user at will), the hot gas discharged by the compressor is re-introduced into the wall of the ice maker to replace the cryogenic liquid refrigerant. In this way, a film of water is formed between the ice and the wall of the evaporation tube, which will lubricate the ice when it falls freely into the trough below by gravity. The water generated during the ice mining cycle will be returned to the storage tank through the porous groove, which also prevents the wet ice from being discharged by the machine.
