Description

Technical Field

[0002] Chillers are mainly used in slicing workshops. They rely on the chiller to provide circulating cold water that is injected into the drum in the slicer, so that the product is cooled into layers on the surface of the drum. The drum passes through a scraper to form a sheet product. In order to improve slicing efficiency and product packaging capabilities, it is necessary to increase the speed of the drum, and the drum needs to provide a lower temperature to meet the needs of rapid cooling. For this reason, we lowered the set temperature of the chiller and found that a small amount of ice crystals appeared in the circulating water, causing abnormal noise from the circulating water pump. In addition, the sliced ​​products are produced intermittently. After shutting down in winter, the circulating water of the chiller must be discharged to prevent the circulating water from freezing and damaging the unit. This not only causes a waste of water resources but also fails to effectively reduce the slicer drum temperature. Therefore, it is very important to design a solution mixing device to prevent circulating water from freezing.
