Three friends talk about the working principle of small ice machine

The small ice machine automatically fills into a water storage tank by replenishing the water valve, and then the water is pumped through the flow control valve to the split head, where the water is evenly sprayed onto the surface of the ice maker, flowing like a water curtain. Through the wall of the ice maker, the water is cooled to the freezing point, and the water that has not been frozen by evaporation will flow into the water storage tank through the porous tank, and the circulation will resume.

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.

1. The chilled water of the water storage tank is continuously circulated through the plate or the divided evaporator by the water pump;

2. After the compressor is operated, it is subjected to suction-compression-exhaust-condensation (liquefaction)-throttle--in the evaporator, vaporization at a low temperature of -10 to -18 degrees. The chilled water continuously condenses into an ice layer on the surface of the lower temperature evaporator at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature control set temperature, the defrosting solenoid valve is often turned on and the heat pump is used to de-ice, and the next cycle is realized.
