What is the working principle of an industrial ice maker? Tips for using an ice maker

is a kind of refrigeration mechanical equipment that produces ice after water passes through an evaporator and is cooled by a refrigeration system refrigerant. According to the different principles of the evaporator and the production process, the shape of the ice produced is 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. . Commonly used small ice machines are mainly composed of control boxes, thermostats, heaters, sensors and ice-making containers. The control box is the core component. A complete ice making process is divided into four steps: water injection, ice making, heating, and ice separation. The compressor is powered on, inhalation, compression, exhaust, condensation (liquefaction), throttling, evaporation, heat absorption, and vaporization. , Forming a low temperature of -18C～10℃ at the evaporator, so the frozen water flowing over the surface of the evaporator condenses into an ice layer. When the ice layer has condensed to a certain thickness and the evaporation temperature of the refrigerant reaches the set temperature of the thermostat, the defrost solenoid valve is energized, and the ice is deiced by a heat pump, and then the next round of ice making is performed. Tips for using ice maker 1. The chilled water pump in the water storage tank continuously circulates through the plate-type or compartmentalized evaporator. After the compressor is running, it undergoes suction-compression-exhaust-condensation (liquefaction)-throttling-and then vaporizes in the evaporator at a low temperature of -10 to -18 degrees. The chilled water is constantly in the water temperature of 0 degrees. The surface of the colder evaporator condenses into an ice layer. When the ice layer condenses to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature-controlled set temperature, the defrost solenoid valve is turned on, and the heat pump is often used for deicing. . Realize the next cycle. 2. The ice maker should be installed in a place far away from the heat source, without direct sun exposure, and well ventilated. The ambient temperature should not exceed 35 degrees Celsius to prevent excessively high ambient temperature from causing poor cooling of the condenser and affecting the system. Ice effect. The ground on which the ice maker is installed should be firm and level, and the ice maker must be level, otherwise it will cause no ice removal and noise during operation. 3. The clearance between the back and the left and right sides of the cbfi ice machine should be no less than 30cm, and the top clearance should be no less than 60cm. 4. The ice maker should use an independent power supply, dedicated line power supply with fuses and leakage protection switches, and reliable grounding. 5. The water used by the ice maker must meet the national drinking water standards, and a water filter device should be installed to filter impurities in the water to avoid clogging the water pipe and polluting the water tank and ice mold. And affect the ice making performance. 6. Turn off the power when cleaning the ice machine. It is strictly forbidden to flush the machine directly with the water pipe. Use neutral detergent for scrubbing. It is strictly forbidden to clean with acidic, alkaline and other corrosive solvents. 7. The ice maker must unscrew the water inlet hose head for two months to clean the water inlet valve filter screen to avoid sand and mud impurities in the water from blocking the water inlet, causing the water inlet to become smaller and causing no ice production. 8. The ice machine must clean the surface dust of the condenser every two months. Poor condensation and heat dissipation will cause damage to the compressor components. When cleaning, use a vacuum cleaner, a small brush, etc. to clean the oil and dust on the condensing surface. Do not use sharp metal tools to clean, so as not to damage the condenser. 9. The water pipe, sink, refrigerator and protective film of the cbfi ice machine should be cleaned every two months. 10. When the ice maker is not in use, it should be cleaned, and the ice mold and the moisture in the box should be blown dry with a hair dryer. It should be placed in a ventilated and dry place without corrosive gas. Avoid storing in the open air. Block ice machineu200d　ice block machine
