Ice maker is a kind of refrigerating mechanical equipment that generates water by cooling water through an evaporator and cooling system refrigerant. According to the different principles of the evaporator and the generation process, the shape of the generated ice is also different. People generally divide ice machines into particle ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. .working principle1. The chilled water pump of the water storage tank continuously circulates through the plate or grid evaporator; 2. After the compressor is operated, it is suctioned-compressed-exhausted-condensed (liquefied) -throttled- -10 to -18 degrees low temperature endothermic vaporization. Frozen water condenses into a layer of ice at a lower temperature evaporator surface at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness, after the evaporation temperature of the refrigerant reaches a temperature-controlled set temperature, the defrost solenoid valve is turned on and the ice is usually removed by a heat pump, and then the next cycle is realized.Commercial Ice Machine ManufacturersPrinciple of operation1 How much water is needed for ice-making (slang is called dosing)! Depending on the amount of ice-making, the modulation pump (plunger pump) adjusts automatically. 2 The body of the ice-making machine is divided into two chambers with a certain density of the inner and outer chambers. Copper tube! The professional term is (evaporation chamber), which is a saying of refrigeration. 3 The outer cavity is a very regular round stainless steel. The center of the cavity has a three-blade scraper. The distance between the blade and the inner wall can be adjusted by itself, generally 3 mm. There are several sets of evenly distributed copper nozzles above the ice skate! 4 The working principle is that when the plunger pump is turned on, the water mixed with salt is sprayed through several filters to evenly spray 0.2 kg of water on the surface of the inner cavity and then on the outer cavity. The cooling surface instantly forms a 3 mm thick ice surface. Under the action of a rotating ice knife, the freshly made ice is broken into small pieces and dropped into the storage bin! The principle of a civilian ice maker is basically the same! The inner cavity is a rotating ice cube box. The working principle of the refrigerator is: 1.The chilled water pump of the water storage tank continuously circulates through the plate or divided evaporator; 2.After the compressor is operated, it is suctioned-compressed-exhausted-condensed (liquefied) -throttle -In the evaporator at a low temperature of -10 to -18 degrees Endothermic vaporization. Frozen water condenses into an ice layer on the lower temperature evaporator surface at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness, the evaporation temperature of the refrigerant reaches a temperature-controlled set temperature After that, the defrost solenoid valve is turned on, often using a heat pump to de-ice. The next cycle is realized. 冰 Ice-making cycle: 补充 Through the make-up water valve, water automatically enters a water storage tank, and then the water is pumped to the The diverter head, where water is sprayed evenly on the surface of the ice maker, and flows across the wall of the ice maker like a water curtain, 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, Restart the cycle.冰 Ice extraction cycle: When the ice reaches the required thickness (thickness can be chosen by the operator / user), the hot air discharged from the compressor is returned to the 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 evaporation tube. This layer of water film will act as a lubricant when the ice falls freely into the groove below by gravity. The water produced during the ice-picking cycle will be returned to the water storage tank through the porous groove, which also prevents wet ice from being discharged by the machine. Condensation of refrigerator: 实现 Air-cooled, water-cooled or evaporative condenser is used. The evaporative type is installed higher than the ice maker, the water-cooled condenser is installed below the ice maker or the refrigeration system, and the air-cooled condenser is installed with the ice maker according to the actual situation Can also be installed outdoors. If required, water-cooled condensers can be used on board or on the coast, using seawater for cooling. Evaporative cooling can be used at higher ambient air temperatures, but from the perspective of efficiency and economics, it is not suitable for water-cooled or air-cooled refrigeration.
