Freezing and unfreezing integrated cabinet and freezing and unfreezing method adopting same

Abstract

The invention provides a freezing and unfreezing integrated cabinet which comprises an incubator body and closed containers. The incubator body comprises a freezing chamber and an unfreezing chamber,and box-type frameworks are fixed in the freezing chamber and the unfreezing chamber correspondingly. Sealing plates are fixed on the upper and lower portions and the front and rear portions of each framework. An air exhaust channel plate is fixed to the left side of each framework, and an air return channel plate is fixed to the right side of the framework. The closed containers are in a flat shape and can be erected in the frameworks of the freezing chamber and the unfreezing chamber in a layered mode. Heat conduction fins are welded or riveted on the upper surface and the lower surface of each closed container in rows. One end of a channel formed by a gap between every two adjacent rows of heat conduction fins is aligned at a corresponding air exhaust hole of the corresponding air exhaust channel plate, and the other end of each channel is aligned at a corresponding air return hole of the corresponding air return channel plate; the air exhaust channel plates are provided with the air exhaust holes; the bottom of the framework in the freezing chamber is provided with a cold air generating device; and the bottom of the framework in the unfreezing chamber is provided with a cold and hot airflow generating device. According to the freezing and unfreezing integrated cabinet, the freezing speed and the unfreezing speed are high, breeding of microorganisms can be effectively restrained, the quality of food is better ensured, and moreover, resources can be greatly saved. The invention further provides a method for freezing and unfreezing meat by adopting the 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
