Description
Technical field
The present invention relates to gas separation technique field, more particularly to a kind of air-separating plant and the cold preservation with it are cold
Freeze device.
Background technology
Refrigerator is to maintain a kind of refrigeration plant of constant low temperature, is also that one kind makes food or other articles keep constant low temperature
The product for civilian use of cold conditions.With the raising of quality of the life, consumer to storing the fresh-keeping requirement of food also more and more higher, especially
It is the requirement also more and more higher of the color and luster to food, mouthfeel etc..Therefore, the food of storage should also be as ensureing during storing, to eat
Color and luster, mouthfeel, freshness of thing etc. keep as far as possible constant.
In the preservation technique of refrigerator, the Oxidation of food, Repiration are all closely related in oxygen and refrigerator.Food
Breathing is slower, and the Oxidation of food is lower, and fresh keeping time is also longer.The oxygen content in air is reduced, to food fresh keeping
With significantly effect.
At present, in order to reduce refrigerator in oxygen content, generally using vacuum freshness retaining or extra arrange in prior art
It is fresh-keeping that device for deoxidizing carries out hypoxia.However, the operation of vacuum freshness retaining is typically more loaded down with trivial details, using being inconvenient；And device for deoxidizing
Generally deoxygenation is carried out using electrolyte etc., device is complex and deaerating effect is not obvious.
Controlled atmosphere technology refers in general manner the atmosphere (gas componant by adjusting closing space residing for storage thing
Ratio or gas pressure) mode come extending the technology of shelf life of food products, its ultimate principle is：In certain closing space
It is interior, obtain being different from the atmosphere of normal air constituent by various regulative modes, to suppress to cause storage thing (usually to be eaten
Material) putrid and deteriorated physiological and biochemical procedure and microorganism activity.Especially, in this application, the controlled atmosphere for being discussed will
It is 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 by the way of nitrogen-rich gas are filled with to closing space to reduce oxygen content the fresh-keeping gas of rich nitrogen oxygen deprivation is obtained
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 is referred to
Nitrogen content exceedes the gas atmosphere of nitrogen content, oxygen content less than oxygen content in above-mentioned normal air in above-mentioned normal air
Enclose.
Find fruit and vegetable in hypoxia water although the history of controlled atmosphere technology can trace back to German biologist in 1821
Metabolism can be reduced at ordinary times to start.But up to this point, because the equipment of making nitrogen volume for being conventionally used to controlled atmosphere is huge
Greatly, it is with high costs, cause the technology to be substantially also limited to using (the storage capacity one on various large-scale professional storages
As at least more than 30 tons).It can be said that being only possible to controlled atmosphere economically using which kind of appropriate gas regulation technology and related device
System compact, mute so as to suitable for family or personal user, are that controlled atmosphere art personnel thirst for solving always
But the technical barrier of the solution that fails all the time.
