Background
Modified atmosphere technology generally refers to technology for prolonging the storage life of food by adjusting the gas atmosphere (gas component ratio or gas pressure) of a closed space where stored objects are located, and the basic principle is as follows: in a certain closed space, a gas atmosphere different from normal air components is obtained through various regulation modes so as to inhibit physiological and biochemical processes and activities of microorganisms which cause the putrefaction and deterioration of stored objects (generally food materials). In particular, in the present application, the modified atmosphere preservation discussed will be specific to modified atmosphere preservation techniques that regulate the proportions of the gas components.
As is known to those skilled in the art, the normal air composition includes (in volume percent, the same applies hereinafter): in the modified atmosphere preservation field, nitrogen-rich gas is generally used to obtain a nitrogen-rich and oxygen-poor preservation gas atmosphere by filling a nitrogen-rich gas into a closed space to reduce the oxygen content, wherein the nitrogen-rich gas is a gas with a nitrogen content exceeding that of the normal air, and the nitrogen content can be 95% -99% or even higher, for example, while the nitrogen-rich and oxygen-poor preservation gas atmosphere is a gas atmosphere with a nitrogen content exceeding that of the normal air and an oxygen content lower than that of the normal air.
The history of modified atmosphere technology dates back to 1821 German biologists that fruits and vegetables can reduce the onset of metabolism at low oxygen levels. However, until now, the technology has been limited to use in large professional storage facilities (storage capacity is typically at least 30 tons) due to the large size and high cost of the nitrogen generating equipment traditionally used for modified atmosphere preservation.

The sides of the two elastic plates 240 facing the cathode plate 230 and the anode plate 220 are respectively provided with a plurality of elastic protrusions, and the positions of the elastic protrusions on the two elastic plates 240 correspond to each other, that is, each elastic protrusion can be matched with one elastic protrusion on the other plate to press the anode plate 220 and the cathode plate 230 together for further clamping the proton exchange membrane 210. The middle part of each elastic plate 240 is hollowed out, or a plurality of air holes are uniformly formed, so as to allow air to pass through.
In this embodiment, electrolytic oxygen scavenging assembly 200 can further comprise: a diffusion layer 270, an activated carbon filter screen, and one or more gaskets 260. The diffusion layer 270 is located between the anode plate 220 and the proton exchange membrane 210 and between the cathode plate 230 and the proton exchange membrane 210, and the material of the diffusion layer 270 is a titanium mesh with a platinum-plated surface, which is used for facilitating electric conduction and allowing water vapor to diffuse. The activated carbon filter screen is disposed on a side of the anode opposite to the proton exchange membrane 210 for purifying the gas entering the anode plate 220. At least one gasket 260 may be positioned between the above-described multi-layered structures, and each gasket 260 is a thin rectangular ring having the same size as the cathode plate 230 and the anode plate 220. Each gasket 260 is made of an elastic material to buffer a pressing force between adjacent layers.
Electrolytic oxygen scavenging assembly 200 further comprises: a fan 250. The fan 250 may be a micro axial fan 250. The blower 250 is disposed on a side of the anode plate 220 opposite to the proton exchange membrane 210, and has a rotation axis perpendicular to the anode plate 220, for blowing the water vapor outside the refrigerating and freezing device toward the anode. The reactant of the anode plate of the electrolytic oxygen removal assembly 200 of this embodiment is water vapor, and therefore, the anode plate needs to be continuously replenished with water so that the electrolytic reaction can be continuously performed. When the electrolytic oxygen removal assembly 200 is turned on, the battery supplies power to the cathode plate 230 and the anode plate 220 respectively, the fan 250 is turned on, and the fan 250 blows air to the anode plate 220 and simultaneously blows water vapor in the air to the anode plate 220 so as to provide reactants to the anode plate 220. Since the ambient air is able to provide sufficient reactant to the anode plate 220, there is no need to provide a separate water source or water delivery device for the electrolytic oxygen scavenging assembly 200.
When the electrolytic oxygen removal assembly 200 is assembled, the cathode plate 230, the anode plate 220, the proton exchange membrane 210, the gasket 260, the elastic plate 240, the diffusion layer 270 and other components are arranged according to the position relationship, and form a multi-layer structure, and then the multi-layer structure is integrally placed in the rectangular accommodating chamber 520. The layer arrangement direction of the multi-layer structure coincides with the front-rear direction of the rectangular accommodation chamber 520. In this embodiment, the multilayer structure in the rectangular accommodating chamber 520 is, from back to front: fan 250, spring plate 240, gasket 260, anode plate 220, gasket 260, diffusion layer 270, proton exchange membrane 210, diffusion layer 270, gasket 260, cathode plate 230, gasket 260, and spring plate 240. When electrolytic oxygen removal assembly 200 is installed, the assembled electrolytic oxygen removal assembly 200 is inserted entirely into the opening of tank 420 and secured within containment chamber 520. The electrolytic operation can be started by connecting the cell to the cathode plate 230 and the anode plate 220. If the user does not need the oxygen removal function of the storage container 100, the entire multi-layered structure may be taken out. In the refrigerating and freezing device of the embodiment, the electrolytic oxygen removal assembly 200 is arranged on the rear side surface of the box body 420, so that a user can install and detach the electrolytic oxygen removal assembly 200 without opening the refrigerating and freezing device, and the user can use the refrigerating and freezing device more conveniently.
The storage container 100 of the present embodiment includes: electrolytic oxygen scavenging assembly 200. The electrolytic oxygen removal assembly 200 is used to consume oxygen from the air in the storage space to obtain a nitrogen-rich and oxygen-lean atmosphere in the space that is conducive to preserving food. The gas atmosphere reduces the oxygen breathing intensity of food (especially fruits and vegetables) by reducing the content of oxygen in the storage space, ensures the basic respiration effect, prevents the food from anaerobic respiration, and achieves the purpose of keeping the food fresh for a long time.
