What are the working principles of the ice maker? How does the ice making process work?

2022/02/10

The cbfi ice machine (English name: ice maker or ice machine) adopts a refrigeration system, and uses a water carrier to pass through a certain device under power to produce ice. The device is called an ice maker. The ice maker 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. According to the principle of the evaporator and the different production methods, the shapes of the ice cubes produced are also different. People generally divide ice machines into pellet ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. according to the ice shape. Wait. So, do you know what the working principle of the ice maker is? How does the ice making process proceed? Let’s follow the editor to learn about it.

   1. The working principle of the cbfi ice machine:    Through the supplementary water valve, the water automatically enters a water storage tank, and then the water is pumped to the shunt head through the flow control valve, where the water is evenly sprayed to On the surface of the ice maker, it flows through the wall of the ice maker like a curtain of water. 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 restart the circulation. 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 cbfi ice 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 play a role of 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. ⒈The chilled water pump of the water storage tank continuously circulates through the plate-type or subdivided evaporator; after the compressor is running, it will undergo suction-compression-exhaust-condensation (liquefaction)-throttling-and then in the evaporator with -10 Low temperature evaporation to -18 degrees absorbs heat and vaporizes.   Frozen water continuously condenses into an ice layer on the surface of the lower 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.

   2. Ice-making mechanism ice process:    Through the water inlet valve, water automatically enters a water storage tank, and then pumps the water to the shunt pipe through the water pump, and the shunt pipe evenly flows the water until it is cooled by the low-temperature liquid refrigerant On the evaporator, the water is cooled to the freezing point. The water cooled to the freezing point will solidify and become 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 by the action of gravity.
