Recently, the 'steamer' mode has been opened all over the country. In some cities, outdoor workers such as sanitation workers, traffic police, couriers, and salesmen have provided free heat-reducing foods such as cold drinks and fruits, and the 'loveless freezer' of the items. People are on duty, and they are fully conscious. Under the scorching sun, they thought they would be robbed by passers-by. In fact, not only did the drinks in the freezer not have 'accidental loss', but things also increased, and they also caused people's heat. Discussion.
As the temperature rises gradually, the rate of food deterioration accelerates. Refrigeration equipment plays an important role as a frozen material for refrigerating and storage. At present, the common refrigeration equipment in life has refrigerators, freezers, refrigerators, fresh cabinets, and refrigerated storage. Cabinets, etc., among which, the freezer plays an important role in ensuring the quality and safety of household ingredients.
Frosting into bacteria breeding 'hotbed' frost-free refrigeration technology hits 'pain point'
We know that in the past, the refrigerator used a single cooling method, the refrigeration was uneven, and the food refrigeration effect was not ideal. However, the refrigerator now uses double refrigeration technology to solve the technical problem that is difficult to overcome by the single refrigeration method. The refrigeration balance makes the cabinet have no cooling dead zone. It is reported that a company adopts dual refrigeration technology, which can accurately set and control the temperature of the refrigerating and freezing compartments through two completely independent cooling circuits, which can bring excellent cooling effect.
In addition, many users will find that after a period of freezing, the ingredients in the freezer will be accompanied by a thick layer of frost, but few people will think about the food safety problem behind the frosting, and some people even think that frosting is strong in freezing. According to relevant surveys, the bacterial microbes in the food after cold freezing frost will be more than ten times that of the original, which can easily induce various gastrointestinal diseases and become a potential 'killer' that affects personal health.
Everyone thinks that it is possible to breed bacteria in a low temperature environment. In fact, low temperature can only inhibit the growth rate of bacteria, such as Listeria, Salmonella and other psychrophilic bacteria. They can still grow and reproduce in low temperature environment. Therefore, they are often ignored. The thick frost layer in the freezer has become a 'hotbed' for bacteria breeding.
In fact, the frosting of the freezer is not only easy to breed bacteria, affecting the quality and safety of the product, but also has other drawbacks, such as slow cooling, fast power consumption, shortening the service life of the compressor, occupying space, reducing the amount of refrigerated food, etc. In this case, how do you deal with the safety hazards caused by the frosting of the freezer and the breeding of bacteria?
Insiders pointed out that on the one hand, users need to regularly clean the frost layer in the freezer, which can be treated by natural deicing, hot water deicing, hot air deicing, etc., but it takes time and effort to eradicate; on the other hand, the freezer Manufacturing companies should increase research and development efforts, adopt advanced refrigeration technology, reduce temperature difference, ensure air circulation and circulation, and smooth water drainage. It can not only solve the frosting problem in the freezer, but also save energy and energy, and lock up nutrition. The purpose of lasting preservation.
At present, more and more air-cooled frost-free refrigerators and refrigerators are on the market, which adopt independent double-cycle and comprehensive cold air technology to reduce bacterial cross-infection and ensure food quality and safety. In addition, there is another refrigeration technology and the past. Different from direct cooling and cold cooling of the freezer, the air-cooling and frost-free technology effectively solves the problem of cold air circulation and moisture discharge. At the same time, a double-layer food basket and a lower cold storage partition are arranged at the top of the freezer to ensure the cold air flow and direct frost cooling. This user 'pain point', bringing consumers a new style of air-cooled, frost-free and fresh-keeping life.
It can be seen that the freezer not only allows outdoor workers to feel the coolness in the hot summer, but also plays an important role in refrigerating and preserving the food to prevent food spoilage. It is worth noting that frosting in the freezer is easy to breed bacteria. The hotbed', the user should pay attention to it. The author believes that with the development and popularization of frost-free refrigeration technology, it will be able to completely solve the 'pain point' of customers' freezer frosting.
