Ice maker machine


Ice machine is a kind of refrigeration mechanical equipment that generates ice after water is cooled by the refrigerant of the refrigeration system through the evaporator. The refrigeration system is used, and the water carrier is used to produce ice after passing through a certain equipment in the electrified state. According to the principle of the evaporator and the different production methods, the shapes of the ice cubes generated are also different; people generally divide ice machines into granular ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc.

working principle

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 film of water is formed between the ice and the wall of the evaporator tube, and this film of water will act as a lubricant when the ice falls freely into the groove below by 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 through the plate or grid evaporator by the water pump;
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, after the evaporation temperature of the refrigerant reaches the set temperature of the temperature control, the defrosting solenoid valve is turned on, usually in the form of a heat pump to deicing, 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, 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 cube and the evaporator, and this layer of water film makes the ice cube break away from the evaporator, and when the ice cube falls freely into the ice storage tank below by the effect of gravity.


main classification

Ice machines can be divided into commercial ice machines, household ice machines, and industrial ice machines.

Ice machines are divided into ice shapes: granular ice (cylindrical, cube, moon), snowflake, scale ice, plate ice, tube ice, and the latest spherical ice.

Granular ice is divided into spray type, flowing water type and immersion type according to the ice making method.

Cylindrical ice is generally made of spray ice, which has a low freezing point, which can reach below minus 20°C. The contact surface between the cylindrical surfaces is small, it is not easy to stick together, and it is convenient to use ice. Cylindrical ice cubes have high hardness, low temperature, and crystal clear ice cubes. They are suitable for cooling foreign wines. The slow melting speed will not dilute the foreign wines and affect the taste of foreign wines. The disadvantage of cylindrical ice machines is that the ice production efficiency is relatively low. , generally used for the production of small bar table ice machines.

The temperature of flake ice is -6℃~-12℃, which is most suitable for cooling in industrial processing and transportation of perishable items. It is often used for seafood display on the fresh counter of supermarkets. Large scale ice can also be used in cement plants, chemical plants, meat joint factories, marine fisheries, etc.

The cooling method can be divided into: water-cooled ice machine, air-cooled ice machine.
