Specific embodiment
The refrigerating device for possessing hyperoxia storage meat function of the embodiment of the present invention uses oxygen-enriched membrane component while being fruits and vegetables
Fresh-keeping the first closed storing subspace and realize that the second closed storing subspace of hyperoxia storage meat function provides atmosphere.
The operation principle of wherein oxygen-enriched membrane component is that infiltration rate when oxygen permeable membrane is passed through using each component in air is different, in pressure differential
Under driving, preferentially by oxygen permeable membrane, in the prior art, oxygen permeable membrane is generally used for preparing oxygen oxygen in making air, so that
The field application such as medical treatment, fermentation, burning.In embodiments of the present invention, refrigerating device then discharges oxygen using oxygen permeable membrane,
So that the oxygen concentration of the first closed storing subspace declines, the atmosphere preserved beneficial to fruits and vegetables is realized, while using discharge
Oxygen realize beneficial to hyperoxia store up meat atmosphere.
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 field,
The fresh-keeping gas atmosphere of rich nitrogen oxygen deprivation is generally obtained by the way of reducing oxygen content using nitrogen-rich gas are filled with to closing space
Enclose.Those skilled in the art will be appreciated that nitrogen-rich gas refer to the gas that nitrogen content exceedes nitrogen content in above-mentioned normal air
Body, 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 atmosphere of nitrogen content, oxygen content less than oxygen content in above-mentioned normal air in above-mentioned normal air.
Although there is also controlled atmosphere technology in the prior art, its history can trace back to German biologist's hair in 1821
Existing fruit and vegetable can reduce metabolism in low oxygen level and start.But up to this point, protected due to being conventionally used to controlled atmosphere
The fresh equipment of making nitrogen is bulky, with high costs, causes the technology substantially also to be limited to use in various large-scale specialties
On storage (typically at least more than 30 tons of storage capacity).Therefore in the prior art one in the small-sized refrigerating equipment such as refrigerator
As still use vacuum freshness retaining technology.
In the present embodiment, by above-mentioned oxygen-enriched membrane component economically by Air-conditioning system miniaturization, mute, so as to be applicable
In the small-sized refrigerating equipment such as refrigerator, while preserving fruit and vegetable utilizing atmosphere is formed, the oxygen shape of discharge is made full use of
Into hyperoxia atmosphere.
Can greatly improve the fresh keeping property of storing using air conditioning technology in refrigerating equipment, but different food
Corresponding optimal gas composition is that different, such as fresh water fruits and vegetables need relatively low oxygen concentration to suppress aerobic
Breathing, reduces consumption of the respiration to idiotrophic material；And for fresh beef, mutton and pork etc., it is referred to as red meat
Then need higher than the oxygen concentration (being referred to as hyperoxia in the present embodiment) in air, in food packaging industry live fresh pork packaging
Gaseous state is oxygen-enriched state, and its oxygen concentration is generally 25%-70%, higher than the oxygen content in normal air, therefore
Can the long period holding meat be in cerise.
Color in red meat comes from the myoglobins in these animal flesh, and myoglobins is that a kind of being played to oxygen transmits work
Protein, if oxygen content is too low during storage, can lack oxygen in muscle, cause myoglobins and oxygen knot
The position of conjunction is replaced by water, and muscle is in kermesinus or purple；Conversely, improving the concentration of oxygen, red meat can be made to keep for a long time
Red shade, keeps its outward appearance.The atmosphere beneficial to hyperoxia storage meat mentioned in the present embodiment refers to oxygen content 25%
To 75% gaseous environment.
Fig. 1 shows the comparison diagram of the fresh-keeping effect of cold fresh meat under different oxygen concentrations.Abscissa is represented and put in figure
Enter the time in oxygen environment, the time is day；Ordinate represents the juice loss rate of cold fresh meat；Three curves in figure are -2
Under conditions of DEG C, after 20%, 45%, 70% oxygen concentration storage sirloin is respectively adopted, test is warmed up to ox after normal temperature
The juice loss rate of lean pork taken under the spinal column of a hog.Wherein curve 1 represents the test result (oxygen concentration close in air) of 20% oxygen concentration；
Curve 2 represents the test result of 45% oxygen concentration；Curve 3 represents the test result of 70% oxygen concentration.Can from figure
Go out oxygen concentration and be respectively 45% and 70% juice loss rate and increase with the time to keep rule substantially close, 70% juice loss
It is less slightly.But 20% concentration is compared with other two curves.Other two articles of curves were just significantly larger than since the 4th day, can be seen
Go out oxygen condition high compared with normal air state, have significant effect to the fresh-keeping of red meat.
