Freezing and thawing integrated cabinet and method for freezing and thawing using the integrated cabinet

Abstract

The invention provides a freezing and thawing integrated cabinet, the integrated cabinet includes an insulated box and an airtight container, the insulated box includes a freezing room and a thawing room, both the freezing room and the thawing room are fixed with a box-shaped frame, the upper, lower, front and rear sides of the frame are The sealing plate is fixed, the air outlet plate and the return air channel plate are fixed on the left and right sides of the frame, the airtight container is flat and can be erected in layers in the frame of the freezing room and the thawing room, the upper and lower surfaces of the airtight container are welded or riveted There are rows of heat-conducting fins, and one end of the channel formed by the gap between two adjacent rows of heat-conducting fins is aligned with the air outlet hole of the air outlet channel plate, and the other end is aligned with the return air hole of the air return channel plate. An air outlet is provided, a cold air generating device is provided at the bottom of the frame in the freezing chamber, and a cold and hot air flow generating device is provided at the bottom of the frame in the thawing chamber. The integrated cabinet of the present invention has fast freezing and thawing speeds, can effectively inhibit the reproduction of microorganisms, better ensure the quality of food materials, and can greatly save energy. The present invention also provides a method for freezing and thawing meat by using the above-mentioned integrated cabinet.

Description

technical field [0001] The present invention relates to the technical field of food freezing and thawing, in particular to a freezing and thawing device for fresh food, and more particularly to a freezing and thawing integrated cabinet that uses cold and heat exchange to quickly freeze and thaw food. The present invention also relates to a method for freezing and thawing meat using the integrated cabinet. Background technique [0002] Freezing refers to the process of freezing the liquid water in food such as fish and meat into a solid state by low temperature. This is a safe and healthy way of preservation, which can effectively inhibit the growth and reproduction of microorganisms in food and prevent food from deteriorating. It is also easy to restore to its original shape. Thawing is the reverse process of freezing, which melts the ice crystals formed during freezing into water. In daily life, in order to prolong the storage time of fresh and live ingredients, freshly p...

AI Technical Summary

Problems solved by technology

In daily life, in order to prolong the storage time of fresh and live ingredients, freshly purchased ingredients are generally stored in freezers or freezers of household refrigerators. The freezing temperature of existing freezers or freezers of household refrigerators is generally set at minus 16 ℃, this is set considering that the ingredients can be stored for more than 3 months. For the catering industry or family, the storage time of the ingredients is generally a few days to more than ten days. This setting not only wastes energy, but also requires cooking. After a long period of thawing; in addition, the existing freezing device (especially the cold storage) and the thawing device (usually located in the kitchen) are generally not located in the same place, and the distance is relatively long, resulting in a long time for transferring ingredients in the middle, which increases the In addition, the existing freezing and thawing device, in the process of freezing and thawing the food, the freezing device and thawing device only cools or heats the entire space where the food is located, and does not directly affect the food where the food is located. Localized areas of the system apply energy exchange, causing it to freeze and thaw poorly
