Cold storage refrigeration device and storage container thereof

Abstract

The invention provides a cold storage refrigeration device and a storage container thereof, wherein the storage container comprises an electric deoxygenization assembly. The electric deoxygenization assembly is used for consuming oxygen of the air in the storage space, so that the nitrogen-enriched oxygen-deficient gas atmosphere can be obtained in the storage space to facilitate food fresh-keeping. According to the gas atmosphere, the content of oxygen in the storage space is reduced, the oxygen respiration intensity of the food is reduced, meanwhile, the respiration action of the foundationis ensured, and the oxygen-free respiration of the food is prevented, so that the purpose of preserving the food for a long time is achieved. In addition, the electric deoxygenization assembly is placed at the rear part of a drawer and is close to the air return opening of an air duct. The air flow at the position returns to the air duct of the refrigerator again, and the humidity of the positionis larger than the humidity of other positions of the refrigerator, so that the reaction of the electric deoxygenization assembly is facilitated. After the water gas near an electrolysis device is consumed, the air circulation of the air-cooled refrigerator is fast, the water gas at other positions can be rapidly supplemented, and the rapid reaction is maintained.

Description

technical field [0001] The invention relates to the field of refrigeration and freezing, in particular to a refrigeration and freezing device and a storage container thereof. Background technique [0002] Modified atmosphere preservation technology generally refers to the technology of prolonging the life of food storage by adjusting the gas atmosphere (gas composition ratio or gas pressure) in the closed space where the storage is located. The basic principle is: in a certain closed space A gas atmosphere different from normal air components is obtained through various adjustment methods to inhibit the physiological and biochemical processes and microbial activities that cause the storage (usually food) to deteriorate. In particular, in this application, the discussed modified atmosphere fresh-keeping will be specifically aimed at the modified-atmosphere fresh-keeping technology that adjusts the ratio of gas components. [0003] Those skilled in the art all know that norma...

Problems solved by technology

But until now, due to the large size and high cost of nitrogen-generating equipment traditionally used for controlled atmosphere preservation, this technology has basically been limited to use in various large-scale professional storages (storage capacity is generally at least 30 tons or more).

It can be said that what kind of appropriate gas adjustment tec
