In our daily life, the refrigerator has become one of the essential household appliances. Among many types of refrigerators, the fresh-keeping freezer plays an important role in food preservation because of its unique design and function. In order to keep the freshness and taste of food better, many modern fresh-keeping freezers are equipped with an important component-humidity adjustment handle. This paper will introduce in detail the function, usage and importance of this device to improve the food preservation effect.
First, what is the humidity adjustment handle?
Humidity adjustment handle is a small device installed inside the fresh-keeping freezer, usually next to a drawer or compartment. It adjusts the relative humidity level in the fresh-keeping space by controlling the moisture content in the air, thus providing the best preservation environment for different types of food. Generally speaking, different foods have different requirements for the humidity required for storage:
Vegetables: Need high humidity (about 85%95%) to keep fresh.
Fruit: Need a lower humidity (about 70% to 80%), too high may lead to rot.
Meat/seafood: It is generally recommended to place it in a low humidity environment (about 60% to 70%) to prevent bacterial growth.
Second, how to use the humidity adjustment handle correctly
1. Understand the food demand: First, determine the appropriate humidity range according to the type of food to be stored.
2. Turn the adjustment knob: In most cases, the humidity adjustment handle will be marked with corresponding scale indications, such as "high", "medium" and "low". Users only need to select the appropriate gear as needed to complete the setting.
3. Check and adjust regularly: Due to seasonal changes and other reasons, indoor temperature and air humidity will change, so it is recommended to re-evaluate whether the current settings are still appropriate at regular intervals and make corresponding adjustments.
Third, why do you need humidity control?
Proper humidity control can significantly prolong the shelf life of food and reduce nutrient loss;
For green leafy vegetables, high humidity helps to slow down the dehydration speed and keep them crisp and tender for a longer time;
Fruits can avoid skin softening too fast or mildew at low humidity;
Meat and seafood products benefit from dry environment, which can effectively inhibit the growth and reproduction of microorganisms and reduce food safety risks.
IV. Conclusion
In short, when purchasing and using fresh-keeping freezers, be sure to check whether they have good humidity management functions and learn to use these tools reasonably. Only in this way can all kinds of ingredients stored at home always be in an ideal state, which can not only ensure the health and safety of the diet, but also save resources and reduce waste from the source. I hope the above content will help you!
