With the advent of refrigerators, equipment has become indispensable in production and at home. It is almost impossible to do without this device, since with it the freshness of many products is preserved. It is only necessary to correctly regulate the temperature, which should be low.
Use of the device will be when the operating mode is normal. But the equipment of each manufacturer may differ in performance. Still, there are standards by which the temperature is set in the refrigerator, in the freezer.
Because of what are the indicators different everywhere?
According to technical standards, the equipment has temperature standards applied by all manufacturers. It turns out that the consumer can independently establish the modes, but only in reasonable terms. Everywhere there is a minimum and a maximum, within which the regulator does not work. What temperature in the refrigerator freezer will be determined by the brand of technology.
Why is this needed? This is due to the fact that each product has its own temperature, at which it will be fresh for a long period. In this case, the mode should not be violated. Each product has its own suitable atmosphere, so the temperature in the refrigerator, in the freezer is different everywhere. The following products can be taken as an example:
- milk: from +2 to +6 degrees;
- eggs: from +2 to +4;
- vegetables: from +4 to +6;
- fish: from -4 to -8;
- meat: from +1 to +3.
Each product has its own characteristics and storage temperature. This will keep freshness for a long time. Manufacturers equip refrigerators with various departments, where each has its own regime.
Freezer temperature
What can be the temperature in the freezer of a home refrigerator? Depending on the type of equipment, this figure is from -6 to -25 degrees. That is why products are placed in the department for long-term storage. The minimum temperature in the refrigerator freezer is used for severe freezing. The optimal indicator is within -18 degrees, so it is set practically by manufacturers.
What temperature is set in the refrigerator freezer depends on what will be there. Identifying the lowest possible score is easy. On almost every equipment, there are snowflakes or asterisks on the controller’s panel with which the temperature in the freezer is recorded . Each of them has an indicator of 6 degrees. After counting the number of snowflakes, you can establish what temperature in the freezer can be.
Freshness zone
Such a department is not present in every refrigerator, it is usually present in new equipment. The freshness zone is located in the cooling chamber. There, a temperature of about zero is set, which allows you to slow down the development of microorganisms in the products. Therefore, they persist much longer.
There are 2 types of freshness zone:
- box;
- a chamber in which there is its own temperature and humidity.
Usually there is no more than +1 degree, because of which the products do not freeze, but retain valuable properties. Fish, meat, cheese, sausage, milk are placed here. This department is designed to cool drinks, except beer and kvass, as they are stored at high temperature.
Other departments
The upper shelves and the department near the freshness zone have a temperature of +2 to +4. They are used to store eggs, pastries, cakes, semi-finished products, dairy products. Meat and fish can also stay there, but no more than 36 hours.
The middle shelf has an indicator from +3 to +6. It serves for soups, sauces, ready meals. The lower compartment is for vegetables. It is set from +6 to +8 degrees. The department serves for short-term storage.
Types of equipment adjustment
All refrigeration equipment has control methods. Depending on the brand, such devices can be divided into:
- electronic: on the refrigerator there is a touch panel that serves to set the desired indicators;
- mechanical: inside any camera there is a shift knob that is twisted to obtain the desired mode.
If you are not sure what temperature in the refrigerator (in the freezer) should be set, then you need to look at this information in the equipment passport. There are all the modes necessary for a particular brand of equipment.
Proper use of the refrigerator
Once the temperature in the refrigerator (in the freezer) is set, you do not need to switch anything. The modes indicated in the documentation for the equipment are supported automatically. If the indicators change independently, then this indicates a malfunction of the equipment. To avoid this, you need to follow simple rules for the use of equipment:
- Do not place warm and hot products, they must cool to room temperature;
- it is necessary to regularly wash the equipment, so that microbes will not start inside;
- products in open packages must be used faster;
- pay attention to the shelf life of products;
- you need to tightly close the door of the device, as well as control the quality of the seal, which is located around the perimeter of the doors;
- you should not put a lot of products at once, since the air circulation should be free;
- it is advisable to place packaged products in the equipment, which will protect against the appearance of unpleasant odors, drying out, and even better to use plastic or glass containers.
Compliance with the rules for setting the temperature will avoid spoilage of products. The equipment will work normally, which will ensure its long-term functioning.
