Ice making principle
The water enters the water distribution tray from the water inlet of the flake ice machine evaporator, and the water is evenly sprinkled on the inner wall of the evaporator through the sprinkling water pipe to form a water film; the water film exchanges heat with the refrigerant in the evaporator flow path, and the temperature is rapid. Lowering, a thin layer of ice is formed on the inner wall of the evaporator, which is broken into pieces of ice under the squeezing of the ice knife and falls into the ice storage from the ice falling port. Part of the water that has not formed into ice passes through the water tray and returns from the water return port to the cold water tank through the cold water circulation pump.
Ice making cycle
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 reservoir through the porous tank and resume the cycle.
Ice picking cycle
When the ice reaches the required thickness (normally, the thickness of the ice is 1.5-2.2 MM), the hot gas discharged from the compressor is redirected back into the wall of the ice maker to replace the low temperature liquid refrigerant. This forms a film of water between the ice and the wall of the evaporation tube. This layer of water will act as a lubricant when the ice falls freely into the groove below by 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.
It is realized by air-cooled, water-cooled or evaporative condenser. The evaporative type is installed above the ice machine, the water-cooled condenser is installed below the ice machine or below the refrigeration system, and the air-cooled condenser is installed with the ice machine according to the actual situation. It can also be installed outdoors. If desired, water-cooled condensers can be used on board or on the coast, using sea water for cooling. Evaporative cooling can be used in ambient air temperatures, but it is not suitable for use in water-cooled or air-cooled refrigeration in terms of efficiency and economy.
