The ice maker machine is a kind of refrigeration mechanical equipment that produces ice after the water passes through the evaporator and is cooled by the refrigeration system refrigerant. The refrigeration system uses the water carrier to produce ice after passing through a certain equipment in the energized state. According to the principle of the evaporator and the different production methods, the shape of the ice cubes produced is also different; people generally divide ice machines into cube ice machines, flake ice machines, plate ice machines, tube ice machines, and ice block machines based on the ice shape. Hockey machine and so on.
How the ice maker machine works
Through the supplementary water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the diverter head, where the water is evenly sprayed on the surface of the ice maker machine and flows through the ice maker machine like a water curtain On the wall surface, the water is cooled to the freezing point, and the water that has not been evaporated and frozen will flow into the water storage tank through the porous tank, and the circulation will restart.
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 re-introduced into the wall of the ice maker machine to replace the low-temperature liquid refrigerant. In this way, a thin film of water is formed between the ice and the wall of the evaporation tube. This water film will act as a lubrication when the ice falls freely into the groove below by gravity. The water produced during the ice picking cycle will return to the water storage tank through the porous tank, which also prevents the wet ice from being discharged by the machine.
1. The chilled water pump in the water storage tank continuously circulates through the plate or compartment evaporator;
2. After the compressor operates, it undergoes suction-compression-exhaust-condensation (liquefaction)-throttling-and then evaporates at a low temperature of -10 to -18 degrees in the evaporator to absorb heat and vaporize. 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 has condensed to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature-controlled setting temperature, the defrost solenoid valve is turned on, and the deicing is usually performed in the form of a heat pump, and then the next cycle is realized.
Ice making process
Through the water inlet valve, the water automatically enters a water storage tank, and then is pumped to the shunt pipe by the water pump. The shunt pipe evenly flows the water to the evaporator cooled by the low-temperature liquid refrigerant. The water is cooled to the freezing point, and these are cooled to the freezing point. The water will freeze into ice, and the water that has not been frozen by the evaporator will flow into the water storage tank and restart the circulation through the water pump.
When the ice cube reaches the required thickness, it enters the deicing state, and the high-pressure hot air discharged from the compressor is led to the evaporator through the reversing valve to replace the low-temperature liquid refrigerant. In this way, a water film is formed between the ice cubes and the evaporator. This water film causes the ice cubes to leave the evaporator. When the ice cubes fall freely into the ice storage tank below under the action of gravity.
