As one of the indispensable appliances in modern homes, refrigerators provide us with a convenient way to store food. And during the use of the refrigerator, the temperature setting plays a crucial role in the preservation quality of the food. This article will focus on the temperature difference between 1st and 4th cold levels in the refrigerator, and analyze the impact of this difference on food preservation, so as to help readers make better use of the refrigerator to ensure that the food is fresh and safe.
1. The temperature range of 1st level cold and 4th level cold.
Refrigerators often have multiple temperature levels to accommodate the preservation needs of different foods. In most refrigerators, 1st cold usually indicates a lower temperature setting, while 4th cold indicates an extremely low temperature setting. Specifically, the temperature range of the first cold gear is roughly between 5 and 7, while the temperature range of the fourth cold gear is usually between -18 and -20.
2. The effect of 1st and 4th levels of cold on food preservation.
Due to the significant temperature difference between the 1st and 4th levels of cold, they also have a significant impact on the preservation of different types of food.
1st gear cold application.
The temperature of Tier 1 cold is milder, which is suitable for storing some foods that are not easily affected by low temperatures. For example, foods such as vegetables, fruits, cheeses, etc., tend to lose moisture or become stale at lower temperatures, so they are more suitable for storage in a cold environment in Gear 1. In addition, some foods that require slow ripening, such as certain types of cheese and wine, can also be well preserved at cold temperature in Variable 1.
4 levels of cold application.
In contrast, the extremely low temperature of 4 cold is more suitable for storing foods that need to be stored for a long time or are perishable. For example, foods such as meat, seafood, frozen dumplings, etc., are prone to spoilage or bacteria growth at higher temperatures, while they can be effectively refrigerated or frozen in a low temperature environment of -18 to -20. In addition, for some foods that need to be frozen quickly, such as ice cream or fresh juices, Frost 4 also provides a fast and stable low temperature environment.
3. How to choose the right temperature range.
When choosing the temperature range of the refrigerator, two main factors should be considered: one is the type of food and the preservation needs;The second is the actual performance and use environment of the refrigerator.
First of all, for different kinds of food, the appropriate temperature range should be selected according to its preservation needs and characteristics. For example, if the refrigerator is mainly stocked with foods that are not susceptible to low temperatures, such as vegetables, fruits, and dairy products, then choosing Variable 1 Cold may be sufficient. And if you need to store a lot of meat, seafood or other perishable foods in the refrigerator, then Variable 4 cold is more suitable.
Secondly, the actual performance and use environment of the refrigerator are also factors that need to be considered when choosing a temperature range. Different brands and models of refrigerators may differ in terms of cooling efficiency and energy consumption. At the same time, the use environment of the refrigerator will also affect its cooling effect. For example, in hot climates, refrigerators may require higher cooling capacity to maintain the set temperature. Therefore, when choosing a temperature range, the performance of the refrigerator and the environment in which it is used should be considered to ensure that the food can be preserved optimally.
IV. Conclusions. In summary, the temperature difference between 1st and 4th cold levels has an important impact on the preservation of food. By understanding the temperature requirements of different foods and the actual performance and use environment of the refrigerator, we can set the temperature level of the refrigerator more reasonably, so as to ensure the freshness and safety of the food. At the same time, it also helps us to make better use of the functions of the refrigerator and improve the quality of life.
