Description

A kind of refrigerator
Technical Field
The utility model relates to a refrigerator technical field especially relates to a refrigerator.
Background
At present, the conventional food thawing methods include the following methods:
the method is characterized in that cold water, warm water, even brine and vinegar are used for soaking and unfreezing, the method seems to be fast, but the effect is poor, when the food is unfrozen by water directly, the ice on the outer layer can be dissolved firstly, and the food in the food is slowly melted, so that the ice can expand and break cells, nutrient substances in the food are lost along with the water, and the taste is also poor during cooking. Because of the long soaking time, the cold water also dissolves nitrogenous substances and vitamins, but the amount of dissolution is less than that of the hot water. The water in which the food is soaked still contains microorganisms, but only grows at a slightly slower rate.
Thawing with hot water, which is done by cooking immediately after thawing with hot water, is not scientific. The frozen food is soaked in hot water, the surface of the frozen food is rapidly heated and thawed, the temperature is raised to be more than 20 ℃, the surface of the frozen food is possibly discolored, the frozen food is not thawed at all in the interior of the frozen food, the frozen food can be called as a 'half-cooked' state, the heat transfer efficiency is lowest at this time, and if the frozen food is taken out, the middle of the frozen food is not thawed. If thawing is continued, the proliferation of microorganisms is extremely feared, and it has been found that the water used to brew the food becomes turbid because of the deterioration of the nutritional value and the umami taste of the food due to the soluble nitrogen-containing substances in which a large amount of the food is dissolved.
Thawing directly at room temperature, and directly placing the food at room temperature to allow it to self-defrost at room temperature. Because the natural temperature is difficult to control, the operation is easy to cause uneven thawing, or the outer layer loses a great deal of water and the food is hard like stone, thereby affecting the taste and the nutritional value of the food. Particularly, bacteria are rapidly propagated in summer, foods are easy to deteriorate when being thawed at normal temperature, and if the thawing time is long, the foods are not fresh and even go bad.
The refrigerating chamber is defrosted, which is a safe and sanitary method, and can ensure the consistent speed of internal and external defrosted while shortening the defrosted time as much as possible. The meat is taken out from the freezing chamber half a day in advance, packaged by a preservation box or a preservation bag and put in a refrigerating chamber of a refrigerator for natural thawing, so that the meat cannot deteriorate to lose nutrition and lose luster. Although this method is good, it needs to be planned in advance. The temporary thawing effect is not good.
