Storage device

Abstract

The invention provides a storage device. The storage device comprises a tank body, a gas separator and an air extractor, wherein the tank body is internally provided with at least one modified atmosphere fresh-keeping space; the gas separator is provided with a modified atmosphere film and is arranged in the mode that the gas separator sucks part of air of the external environment of the gas separator into the gas separator, separates at least part of oxygen in the air out under the action of the modified atmosphere film, and then fills the modified atmosphere fresh-keeping space with the rest of air of the part of air, entering the gas separator, except of the air with the at least part of oxygen is removed; and the air extractor communicates with the gas separator. Through the storage device, nitrogen-rich and oxygen poor gas atmosphere facilitating food freshness keeping can be formed in the modified atmosphere fresh-keeping spaces, the aerobic respiration strength of fruits and vegetables is lowered by lowering the oxygen content in the fruit and vegetable storage spaces through the gas atmosphere, meanwhile, the basic respiration is ensured, and the fruits and the vegetables are prevented from anaerobic respiration, so that the purpose of fruit and vegetable long-term freshness keeping is achieved.

Description

technical field [0001] The invention relates to the technical field of article storage, in particular to a storage device. Background technique [0002] With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored food should also ensure that the color, taste, and freshness of the food remain unchanged as much as possible during the storage period. At present, in order to better store food in the market, there is only one kind of vacuum preservation. Vacuum fresh-keeping methods that are often used are vacuum bag fresh-keeping and vacuum storage compartment fresh-keeping. [0003] Using vacuum bags to keep fresh, consumers need to vacuumize every time they store food, which is cumbersome to operate and not popular with consumers. [0004] Vacuum storage compartments are used to keep fresh. Since the box body is a rigid structure, it is neces...

AI Technical Summary

Problems solved by technology

[0004] Vacuum storage compartments are used to keep fresh. Since the box body is a rigid structure, it is necessary to maintain a vacuum state. The requirements for the vacuum system are very high, and the sealing performance of the storage compartment is very high. Every time an item is taken and placed, the surge More fresh air is taken in, which consumes a lot of energy

In addition, due to the vacuum environment, it takes a lot of effort for the user to open the door of the storage room every time, which causes inconvenience to the user.

Although some storage rooms can be ventilated to the vacuum storage room through the vacuum pumping system, this will cause the user to wait for a long time, and the timeliness is poor

A longer vacuum time will also cause serious deformation of the storage compartment box, that is, the existing storage compartment with a vacuum pumping s
