Want To Know The Ice Making Principle And Process Of The Desktop Ice Machine

Through the supplementary water valve, water automatically enters a water storage tank, and then through the flow control valve, the water is pumped to the splitter head, where the water is evenly sprayed on the surface of the ice maker and flows through the ice maker like a water curtain 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 grooves, and the cycle work will start again.

When the ice reaches the required thickness (thickness can be arbitrarily selected by the operator/user), the hot air discharged from the compressor is reintroduced into the interlayer wall of the ice maker to replace the low-temperature liquid refrigerant.

In this way, a layer of water film is formed between the ice and the wall of the evaporator tube, and this layer of water film will play a lubricating role when the ice falls freely into the groove below under the action of gravity. The water produced during the ice mining cycle will return to the water storage tank through the porous groove, which also prevents the wet ice from being discharged by the machine.

1. The chilled water in the water storage tank is continuously circulated by the water pump through the plate-type or compartmentalized evaporator;

2. After the compressor is running, it goes through suction-compression-exhaust-condensation (liquefaction)-throttling-and then evaporates in the evaporator at a low temperature of -10 to -18 degrees to absorb heat and vaporize. Frozen 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 and the evaporation temperature of the refrigerant reaches the set temperature of the temperature control, the defrosting solenoid valve is turned on, and the deicing is usually performed by a heat pump, and then the next cycle is realized.

Let's take a look at the ice-making process of the desktop ice maker.

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, and the shunt pipe evenly flows the water to the evaporator cooled by the low-temperature liquid refrigerant, and the water is cooled to the freezing point, which is 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 again, and the circulation will start again through the water pump.

When the ice cube reaches the required thickness, it enters the deicing state, and the high-pressure hot gas discharged from the compressor is diverted to the evaporator through the reversing valve to replace the low-temperature liquid refrigerant.

In this way, a layer of water film is formed between the ice cubes and the evaporator. This layer of water film makes the ice cubes leave the evaporator, and when the ice cubes fall freely into the ice storage tank below under the action of gravity.
