By replenishing the water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the splitter head, where the water is evenly sprayed onto the surface of the ice maker, flowing through the ice maker like a water curtain On the wall, the water is cooled to the freezing point, and the water that has not been frozen by evaporation will flow into the water reservoir through the porous tank and resume the cycle. When the ice reaches the required thickness (the thickness can be arbitrarily selected by the operator/user), the hot air discharged from the compressor is redirected back into the ice collector wall to replace the low temperature liquid refrigerant. In this way, a film of water is formed between the ice and the wall of the evaporation tube. This water film will act as a lubricant when the ice falls freely into the groove below by the action of gravity. The water produced during the ice picking cycle will pass through the porous tank back into the water reservoir, which also prevents the wet ice from being discharged by the machine.
