Realistic Application of Flake Ice Machine

May. 14, 2020

Flake ice machine is a kind of ice machine, which can be divided into freshwater flake ice machine and seawater flake ice machine according to the water source. The flake ice is thin, dry and loose white ice with a thickness ranging from 1.0 mm to 2.5 mm. The shape of the flakes is irregular and the diameter is about 12 to 45 mm. Flake ice has no sharp edges and corners and will not stab frozen objects. It can enter the gap between the objects to be cooled, reduce heat exchange, maintain the ice temperature, and have a good moisturizing effect. Flake ice has an excellent cooling effect and has the characteristics of large and rapid cooling capacity, so it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling, etc.

Principle of ice making

Water enters the water separation tray from the inlet of the flake ice machine evaporator, and the water is sprinkled evenly on the inner wall of the evaporator through the sprinkler pipe to form a water film; the water film exchanges heat with the refrigerant in the evaporator flow channel, and the temperature is rapid Lowered, a thin layer of ice was formed on the inner wall of the evaporator. Under the squeeze of the ice knife, it shattered into pieces of ice and fell into the ice storage from the ice outlet. Part of the unfrozen water returns from the return port to the cold water tank through the water receiving tray and passes through the cold water circulation pump.

Ice making cycle

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 onto the surface of the ice maker and flows 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 water storage tank through the porous tank and restart the circulation work.

Ice mining cycle

When the ice reaches the required thickness (normally, the thickness of the ice is 1.5-2.2MM), the hot gas discharged from the compressor is reintroduced back into the 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 evaporation tube. This film of water will play a role of lubrication when the ice falls freely into the groove below by gravity. The water generated during the ice mining cycle will return to the water storage tank through the porous tank, which also prevents wet ice from being discharged by the machine.

Refrigerator condenser

It can be realized by air cooling, water cooling, or evaporative condenser. The evaporative type is installed above the ice machine, the water-cooled condenser is installed below the ice machine or the refrigeration system, and the air-cooled condenser is installed according to the actual situation and can be installed together with the ice machine Can also be installed outdoors. If necessary, the water-cooled condenser can be used on the ship or on the coast, using seawater for cooling. Evaporative cooling can be used in high ambient air temperature, but from the perspective of efficiency and economy, it is not suitable for use under water-cooled or air-cooled refrigeration.
