Refrigerating and freezing device and storage container thereof

Abstract

The invention provides a refrigerating and freezing device and a storage container thereof. The storage container comprises an electrolysis deoxygenization assembly and a moisture permeability assembly. The electrolysis deoxygenization assembly is used for consuming oxygen in air in a storage space, so that a nitrogen-rich oxygen-deficient air atmosphere beneficial to food preservation is obtainedin the space, the intensity of aerobic respiration of food is reduced, and the aim of long-term preserving the food is achieved. When the electrolysis deoxygenization assembly is used for consuming the oxygen in the storage space, a certain moisture is produced in the storage space, so that the inner part of the storage space is more and more humid. Through the moisture permeability assembly, themoisture in the air in the storage space can be conveyed to the outer part of the space through a pervaporation membrane through vaporization penetration, so that the humidity in the storage space still keeps in the appropriate range, and condensate or dropping water is prevented from being produced in the space. In the refrigerating and freezing device provided by the invention, the electrolysisdeoxygenization assembly and the moisture permeability assembly can be used in a matching way, so that food can be preserved favorably.

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 technology and corresponding devices can be used to economically miniaturize and quiet the air conditioning system, making it suitable for families or individual users, is a problem that technicians in the field of air conditioning and fresh-keeping have been eager to solve but have never been able to solve.
