Material) putrid and deteriorated physiological and biochemical procedure and microorganism activity.Especially, in this application, the controlled atmosphere for being discussed will
Specifically designed in the controlled atmosphere technology being adjusted to gas component ratio.
Those skilled in the art know that normal air constituent includes (pressing volume percentage, hereafter together)：About 78%
Nitrogen, about 21% oxygen, about 0.939% rare gas (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, with
And 0.03% other gases and impurity (for example, ozone, nitric oxide, nitrogen dioxide, vapor etc.).In controlled atmosphere neck
Domain, generally obtains the fresh-keeping gas of rich nitrogen oxygen deprivation using nitrogen-rich gas are filled with to closing space by the way of reducing oxygen content
Atmosphere.Here, those skilled in the art know that nitrogen-rich gas refer to that nitrogen content exceedes nitrogen content in above-mentioned normal air
Gas, such as nitrogen content therein can be 95%~99%, even more high；And the fresh-keeping atmosphere of rich nitrogen oxygen deprivation refers to
Nitrogen content is more than the gas atmosphere of nitrogen content, oxygen content less than oxygen content in above-mentioned normal air in above-mentioned normal air
Enclose.
Sealing space often is set used as fresh-keeping chamber, but different types of food pair in storage space in the prior art
The requirement of nitrogen gas concn also and is differed, under sealing space identical nitrogen gas concn, it is impossible to meet different types of food
Fresh-keeping demand, may influence the storage effect of some food, and then reduce the experience of user.

Carrier of oxygen collecting chamber is connected, and specifically, can be connected with aspirating hole 324.Aspiration pump 41 is configured to outwards be taken out by aspirating hole 324
Gas, so that pressure of the pressure of oxygen rich gas collecting chamber less than fresh-keeping space.That is, aspiration pump 41 is in outwards pumping,
Air in fresh-keeping space can flow to oxygen-enriched membrane component, and make in the presence of oxygen-enriched membrane component in fresh-keeping space in air
Part or all of oxygen enters oxygen rich gas collecting chamber, and fresh-keeping space is discharged by by pipeline 50 and aspiration pump 41, so as to protect
The atmosphere that rich nitrogen oxygen deprivation is beneficial to food fresh-keeping is obtained in fresh space.
Oxygen-enriched membrane component is different using the infiltration rate in air during each component gas permeation oxygen permeable membrane, is driven in pressure differential
Under, oxygen preferentially obtains oxygen by oxygen permeable membrane in making air.In some other embodiment, controlled atmosphere film can also be hollow
Tunica fibrosa, controlled atmosphere membrane module is hollow fiber film assembly, and hollow fiber film assembly is hollow using each component gas permeation in air
The transmitance of tunica fibrosa is different, and because oxygen molecule is less than nitrogen molecular, oxygen molecule can preferentially obtain oxygen through hollow-fibre membrane.
