The working principle of ice maker


1) The water pump in the water storage tank circulates continuously through the evaporator.


2) After the compressor runs, water continuously condenses into ice layer on the surface of the lower temperature evaporator at the water temperature of 0 degree. When the ice layer condenses to a certain thickness, the evaporation temperature of the refrigerant reaches the set temperature of temperature control, that is to say, the defrosting solenoid valve is usually connected to defrost by heat pump, and then the next cycle is realized.


3) Ice-making cycle: water automatically enters a storage tank through a supplementary water valve, and then is pumped through a flow control valve to the diversion head, where water sprays evenly onto the surface of the ice maker, flows like a water curtain across 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 pass through the porous tank. Flow into the reservoir and start the cycle again.


4) Ice extraction period: When the ice reaches the required thickness (the thickness can be chosen by the operator 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 pipe, which lubricates the ice when it falls freely into the trough below by the action of gravity.


5) Refrigerator condensation: air-cooled, water-cooled or evaporative condenser. The evaporative condenser is installed above the ice maker, the water-cooled condenser is installed below the ice maker or under the refrigeration system, and the air-cooled condenser can be installed together with the ice maker or outdoors according to the actual situation. If necessary, water-cooled condensers can be used on board ships or along the coast, using sea water for cooling.
