The optimum storage temperature of products in the freezer

In any household refrigerator compartment is provided for storing frozen foods at a low temperature. Freezer is a major consumer of electrical energy device. The intensity of consumption is directly related to the temperature regime of the camera - the lower the temperature, you're more energy.

The answer to the question, what temperature should be kept in the freezer, you can find by studying this article.

The temperature product storage standards

Manufacturers of household refrigeration appliances are made capable of maintaining different temperatures in freezers. Normally, it is in the range: -6-25 ° C.
The vast majority of the default models have normal temperature conditions at -18 ° C.

The fact that European corporations producing household appliances use classification freezers of temperature zones in the range 6 ° C, indicating each of them "*" symbol (star). The number of stars characterizes the maximum freezing capacity of the appliance.

for exampleIf the refrigerator depicted sprockets 3, it is able to cool to -18 ° C.

The exception is the symbol "****". It also corresponds to the minimum cooling -18 ° C, but is provided for units in another category.

Refrigerated compartment designed for short-term storage of products that are eating or prepared in the near future. If food supplies for the future, the storage time can be increased by placing it in the freezer.

What is the optimum storage temperature of products?

Consider the effect of temperature on the storage of certain products:

1. Meat. At a temperature close to zero degrees meat product may expect their preparation a couple of days. Fresh frozen meat in the mode of -8-12 ° C can be stored for a week, and at -14-18 ° C - as much as 5-6 months. At the same meat products are able to maintain their quality of consumer 3 months if frozen until -18- 22 ° C;
2. Fish. The shelf life of frozen fish are very different. Recommended storage temperature fish is - 18 ° C. At this temperature, the fish should be stored from 3 to 12 months, depending on belonging to a particular family and freezing technology. For example, fish of the family Gadidae not lose its nutritional value for 8 months and river inhabitants as walleye, carp, perch, pike, and so on. D. - only six months. Furthermore, you can get acquainted with the rules for storage of frozen fish by examining the GOST 1168-86. When the temperature rises to -10 ° C shelf life is reduced by half;
3. Vegetables They can be stored at -18 ° C for six months or a year. With further finding frozen Though they are not spoiled, but will lose their useful properties. Preservation of the past largely due to the cooling mode. In case of shock freezing - sharp decrease in temperature to -40 degrees - formed ice crystals are so small that they can not disturb the structure of the cells;
4. Fruits and berries They kept about the same as vegetables. Dates frozen at which they begin to lose nutrients is 8-12 months.
5. Margarine. If you for some reason decided to stock up with margarine, know that within 0-10 ° C, he "will live" 45-75 days, and at -10 ° C 20 - 60-90 days, ie.. 2 times more than if you put it in the refrigerator compartment. Some products are not intended to be placed in the freezer. This will lead not to the increase in terms of their safety, but to the impossibility of further use. A typical example - chicken eggs.

How to adjust the temperature

To change the temperature in the refrigerator or freezer cabinet has a control system. They are mechanical (Toggle switches, rotary knobs or wheels with marked divisions and t.) Or sensory (A set of electronic control panels and buttons).

Rules change settings are described in detail in the instruction manual included in the delivery of any instrument.

How do I know how many degrees in the freezer?

The current temperature value can be found on the display, or by placing a thermometer with a sufficiently long negative scale inside the chamber.

Fast freeze function

In some models of refrigerators there is a function of fast freezing. When its activation device switches to maximum intensity mode and quickly goes to a given temperature level. After his achievements, freezer, usually returns to its normal operating mode.
This feature is useful fresh produce, as well as when you turn the device to the network, if necessary, to quickly freeze added in large quantities.

Recommendations for the storage of products in a freezer

In order for your freezer unit served for a long time, and stored it in the products did not have time to deteriorate, it is advisable to stick to some simple rules:

• Do not place in the freezer warm or hot objects;
• Try not to load the camera immediately many items with a high specific heat capacity;
• Pay attention to the expiration date, sign the package with the date bookmark fruit and vegetables harvested in the winter;
• First use in food packaging, have lost their tightness;
• Timely defrost chamber in the case of ice formation on the evaporator surface and carefully wipe it from food residue.
