The working principle of the ice machine
By replenishing the water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the splitter head, where the water is evenly sprayed onto the surface of the ice maker, flowing 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 reservoir through the porous tank and resume the cycle.
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 redirected back into the ice collector wall 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 water film will act as a lubricant when the ice falls freely into the groove below by the action of gravity. The water produced during the ice picking cycle will pass through the porous tank back into the water reservoir, which also prevents the wet ice from being discharged by the machine.
1. The chilled water of the water storage tank is continuously circulated through the plate or the divided evaporator by the water pump;
2. After the compressor is operated, it is subjected to suction-compression-exhaust-condensation (liquefaction)-throttle--in the evaporator, vaporization at a low temperature of -10 to -18 degrees. The 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 condenses to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature control set temperature, the defrosting solenoid valve is often turned on and the heat pump is used to de-ice, and the next cycle is realized.
Ice making process of ice machine
Through the inlet valve, the water automatically enters a water storage tank, and then pumps water to the diverter tube. The diverter tube uniformly 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 solidify into ice, and the water that has not been frozen by the evaporator flows into the water reservoir again, and the circulation is resumed by 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 led to the evaporator through the reversing valve to replace the low temperature liquid refrigerant. Thus, a water film is formed between the ice cube and the evaporator, and the water film separates the ice cubes from the evaporator, and the ice cubes fall freely into the ice storage tank by gravity.
The main classification of ice machines
Ice machines can be divided into commercial ice machines, household ice machines, and industrial ice machines.
From the shape of the ice machine: there are granular ice (cylindrical, square, monthly), snowflake, scale ice, ice, tube ice and so on.
Particle ice is divided into spray type, running water type and immersion type according to ice making method.
Cylindrical ice is generally spray-type ice making. This type of ice making method has a low freezing point and can reach below 20 °C. The contact surface between the cylindrical surfaces is small, it is not easy to stick into a mass, and it is convenient to use ice. Cylindrical ice cubes have high hardness, low temperature and crystal clear ice. They are suitable for the cooling of wine. The slower melting speed will not dilute the wine, but affect the taste of the wine. The disadvantage of the cylindrical ice ice machine is that the ice production efficiency is relatively low. It is generally used in the production of desktop small ice machines.
The temperature of the scale ice is -6 ° C ~ -12 ° C, which is most suitable for the cooling of industrial processing and transportation of perishable goods. It is often used for seafood display in supermarket fresh tables. Large scale ice can also be used in cement plants, chemical plants, meat joint factories, marine fisheries, etc.
