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

Embodiment Construction

[0033] figure 1 is a schematic partial structural diagram of a refrigeration and freezing device according to an embodiment of the present invention; figure 2 yes figure 1 Schematic partial structural view of another view of the structure shown. Such as figure 1 with figure 2 As shown, the embodiment of the present invention provides a refrigerating and freezing device, which may include a box body 20, a main door body, an atmosphere-modulating membrane module 30, an air extraction device 40, a proton exchange membrane module and a refrigeration system.

[0034]The box body 20 may include an inner tank 21 , a shell 27 disposed outside the inner tank 21 , and an insulating layer between the inner tank 21 and the shell 27 . The inner container 21 defines a storage space 211 . Further, a storage container is provided in the storage space 211, and the modified atmosphere fresh-keeping space 11 is provided in the storage container. The modified atmosphere fresh-keeping spac...

Abstract

The invention provides a cold storage and refrigerating device comprising a gas membrane assembly and a proton exchange membrane assembly. The gas membrane assembly is used for discharging oxygen in air from an air conditioning space, so that nitrogen-rich and oxygen-depleted gas atmosphere in favor of food preservation is obtained in the space, and the aerobic respiration strength of fruits and vegetables in the gas atmosphere is reduced through reducing the oxygen content in the fruit-vegetable storage space; at the same time, the basic respiration is ensured, and the anaerobic respiration of the fruits and vegetables is prevented, so that the purpose of long-term preservation of the fruits and vegetables is achieved. The proton exchange membrane assembly can be used for conveying moisture in the air outside the air conditioning space into the space through electrolytic reaction, and the humidity in the air conditioning space is kept in the proper range all the time. In the cold storage and refrigerating device provided by the invention, the proton exchange membrane assembly and the gas membrane assembly can be used coordinately, in favor of food preservation.

Description

technical field [0001] The invention relates to the field of refrigeration and freezing, in particular to a refrigeration and freezing device. 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 normal air composition includes (by v...
