The difference between a direct cooling ice maker and a salt water ice maker

The principle of the direct cooling ice maker: the hollow aluminum plate is used for molding, and the hollow channel between the molds is directly injected with refrigerant. The cooling capacity of the refrigerant directly freezes the water in the ice mold through the aluminum plate. In order to achieve the purpose of rapid freezing. The principle of the salt water ice maker: The principle of the salt water ice maker is that even in ultra-low temperature conditions, high salinity water (sodium chloride) will not freeze, and the refrigerant is scattered in the brine pool through the pipeline. The cooling capacity of the refrigerant is used to cool the brine passing through the pipe wall, and the ice mold filled with half of the tap water is placed in the brine. Let the cooled brine pass through the ice mold to achieve the purpose of freezing the water in the mold. . The salt water ice maker is simple to manufacture and low in cost, and everyone has been using this ice maker for a long time. But there are indeed many problems caused by salt water ice making. One: Use the site: In addition to repairing the large swimming pool, an open space is also needed to put down mold and ice. This requires the construction of a considerable workshop. In modern society where land is increasingly expensive, the larger the civil construction, the higher the cost. The direct cooling ice maker uses an upper and lower system to make ice. It does not require a large pool or large open space to place ice molds, nor does it require empty space to pour ice. This reduced the cost of civil engineering by two-thirds. Two: Labor cost: The salt water ice maker needs to use a crane to put the ice mold into the salt water pool, and then manually inject water. After freezing the ice cubes, you need to use a crane to manually lift the frozen ice cube molds out of the salt water pool, then pour it into the ground and remove the ice cubes from the ground. These complex processes usually require three to four workers to complete successfully. The direct cooling ice maker automatically removes the ice after freezing and then landed. Only one worker is required to slide ice into the ice storage on the ice platform. Save a lot of labor costs, and the efficiency is even faster. Large ice makers (also called ice makers, ice makers, bulk ice makers, in other words, ice makers, large ice makers) have various names, but ice maker factories, especially The direct cooling Tube Ice Machine Dongguan Wanjia is really good. Three: Food safety and workshop hygiene: The ice and water injection process of the salt water ice maker often makes the workshop damp. Bacteria can easily multiply in this environment, so you can't eat salt water sugar coating directly. Workers who have been working in humid environments for a long time are also likely to refuse to work or leave work due to rheumatism. The place where ice is finally used is basically food. As the country pays more and more attention to food safety and citizens have stricter and stricter requirements for food safety, the salt water sanitary belt for ice making will eventually be eliminated. Direct cooling and ice making, no salt water pollution, no humid environment. Ice can be eaten directly, which is an unparalleled advantage of the salt water type. Four: Service life: As we all know, salt water is a highly corrosive substance, and high-salt sodium chloride is also a highly corrosive substance. The service life of salt water ice machines is limited by the corrosive nature of salt water. Therefore, no matter how thick the ice mold you use, corrosion problems still exist. The direct cooling method without salt water completely solves the problem of salt water corrosion, greatly prolongs the service life of the machine, and greatly reduces the equipment failure rate. Five: Energy-saving performance: It is not difficult to find that the cooling capacity of the salt water ice maker needs to cool the salt water first, and then cool the water through the mold. The cooling capacity of the direct cooling refrigerant directly freezes the water through the ice mold. Aluminum is a very fast cooling material. However, due to corrosion problems, the salt water ice model dare not use aluminum plates, and all use thick steel or stainless steel. The thicker the ice mold, the slower the ice, and the ice will become more brittle. The thinner the ice mold, the faster the salt water will corrode. For salt water ice machines, this has become a problem.
