The frozen meat in the refrigerator was wrapped in a quilt for several days without thawing.
The frozen meat in the refrigerator is wrapped in a quilt for several days, depending on the room temperature. It usually takes about 24 hours in summer and about 3 days in winter.

Fundamentally speaking, the refrigerator is an electrical appliance that emits heat to the outside world, and the low temperature of the freezer is far below the freezing point of water. Generally,-15℃ is the default temperature, which is not enough to ensure the crystallization of intercellular water (-30℃, although the difference is only half, and it is not as simple as taking it out of the refrigerator to reach this temperature), but it is enough to show that the meat inside is "frozen" in appearance, and the whole process needs the heat of the meat to be released from room temperature until the temperature in the central part is consistent with that in the box.

Condition 1: At this time, if you wrap the quilt and put it in the refrigerator, you also need to give off heat. At this time, the surface of the meat may need to melt a little ice residue, cool the contact surface to freezing point (that is, it is almost inevitable that quilts will stick to the frozen meat to varying degrees), and then let the quilts repeat the above process. As the saying goes, if you don't thaw for a few days, if you put the quilt in the refrigerator, this problem seems to be much easier.

If you insist on putting this pile of things outside, that's another matter. ...

Condition 2: First of all, the quilt is made of a large number of air-precipitated fiber fabrics and combed cotton fiber fillers, and the air thermal conductivity is not good, which can only be reflected when the air flow is blocked. Fabric blocks the exchange of internal and external air, and filler blocks the small circulation of internal air, all of which make the quilt an excellent heat-resistant material. Considering that these projects are easily influenced by other factors, some necessary conditions are listed:

Sunshine, wind, doors and windows

The heat brought by sunlight in the form of visible light is already considerable (artificial lighting is also difficult to achieve cloudy illumination, so it is difficult to give up such an electricity bill and lamps). If the quilt surface is dark, the thawing process will definitely be accelerated.

The wind blows through the surface fabric, causing the internal circulation to accelerate.

The reasonable use of doors and windows will bring obvious influence on indoor temperature.
