Guangzhou Icesource Co., Ltd. is the inventor of the large ice cube machine(1-20tons daily capacity), using our self-developed technology, such as flat liquid film heat exchange and circulating hot gas ice harvesting to solve the problem of low capacity, high energy consumption, small ice thickness, and unstable harvest of ice that plagues the entire industry. We also offer a one-stop solution for fully automated large ice cube production lines to reduce your labor costs, assess productivity and ensure the safety and hygiene of ice. CBFI is your first choice for setting up an ice factory.
The large-scale edible ice cube machine is a large-capacity ice making machine that produces ice cubes. The ice cubes are hygienic and widely used in places where ice is needed, such as hotels, bars, restaurants, convenience stores, and cold drink shops.
What is the reason for the slow freezing speed of the ice cube machine?
1. The surface of the evaporator becomes dirty, greasy or dusty, and the heat transfer effect decreases. This situation is mainly caused by the long idle time of the equipment, unqualified water quality, and poor equipment use environment. In addition to the poor heat transfer effect of the evaporator In addition, due to the long-term uncleaned dust, the surface of the evaporator becomes too thick, and the heat transfer efficiency is also significantly reduced.
2. Due to the poor thermal insulation effect or sealing performance of the direct cooling square ice machine, the cooling loss is large, and the poor thermal insulation performance is due to the insufficient thickness of the pipeline thermal insulation layer, the uneven thickness of the evaporator plate, and the poor thermal insulation effect, mainly due to the manufacturer's choice of thermal insulation layer thickness. Improper or improper production process, in addition, during the use of the equipment, the thermal insulation and moisture-proof performance of the thermal insulation material may be damaged, resulting in the thermal insulation layer being damp, deformed, or even eroded, and the thermal insulation performance of the thermal insulation material is reduced. Another important reason is that the thermal insulation and sealing performance of the equipment is poor. Generally, condensation occurs around the insulation of the equipment, indicating that the part is not tightly sealed.
3. There is a lot of air or refrigerated oil in the evaporator of the direct-cooled square ice machine, and the heat transfer effect is reduced. Once the refrigerated oil adheres to the inner surface of the evaporator heat exchange tube, its heat transfer coefficient will decrease. Similarly, if the heat exchange If there is more air in the tube, the heat transfer area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the freezing effect will be slowed down accordingly. Oil pollution to improve the heat transfer efficiency of the evaporator.
4. The throttle valve of the ice machine is improperly adjusted or blocked, and the refrigerant flow is too large or too small. Otherwise, the blockage of the throttle valve will directly affect the refrigerant flowing into the evaporator. If the throttle valve is opened too large, the refrigerant flow rate is relatively large. , the evaporating pressure and temperature also increase, and the freezing speed of the ice maker that directly cools the ice cubes will slow down. At the same time, when the throttle valve is too small or blocked, the flow of refrigerant decreases, and the volume of refrigerant in the system also decreases. The speed is also slower.
5. The compressor efficiency is low, the refrigerating capacity cannot meet the ice-making load, the compressor runs for a long time, the wear is serious, the compressor gap increases, the sealing performance decreases accordingly, the air transmission coefficient of the compressor also decreases, and the refrigerating capacity decreases. When the amount of ice is less than the ice-making load, the ice-making efficiency will decrease. By observing the suction and discharge pressure of the compressor, the refrigeration capacity of the compressor can be roughly determined. If the refrigeration capacity of the compressor decreases, the usual method is to replace the cylinder liner and Piston rings, if replacement does not work, other factors should be considered, and the machine should even be removed for maintenance and troubleshooting.
6. There are two main reasons for the insufficient cooling capacity of the ice cube machine system and the insufficient refrigerant circulation. The refrigerant charge is insufficient. Another reason is that there are many refrigerant leaks in the system. In this case, the leak must be found first. point, check each one.
