Specific embodiment

The refrigerating device for possessing hyperoxia storage meat function of the utility model embodiment is closed first using controlled atmosphere film The atmosphere for meeting article storing is formed in storing subspace, for example, takes oxygen permeable membrane to form the atmosphere of oxygen-enriched poor nitrogen. The operation principle of wherein oxygen permeable membrane is that infiltration rate when oxygen permeable membrane is passed through using each component in air is different, is driven in pressure differential Under, preferentially by oxygen permeable membrane, in the prior art, oxygen permeable membrane is generally used for preparing oxygen to make oxygen in air, so as to medical treatment, The field application such as fermentation, burning.In the utility model embodiment, the refrigerating device for possessing hyperoxia storage meat function is then utilized Oxygen permeable membrane discharges oxygen so that the oxygen concentration of the first closed storing subspace declines, and realizes the gas preserved beneficial to food Atmosphere.

In the present embodiment, controlled atmosphere technology stores the atmosphere (gas componant of closing space residing for thing by adjusting Ratio or gas pressure) mode extend the technology of shelf life of food products, its general principle is：In certain closing space In (the first closed storing subspace 271), obtain being different from the atmosphere of normal air constituent by various regulative modes, with Suppression causes to store the activity of thing (usually food) putrid and deteriorated physiological and biochemical procedure and microorganism.Especially, in this reality Apply in example, the controlled atmosphere for being discussed is by 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 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 the fresh-keeping atmosphere of hyperoxia.The fruits and vegetables of storage are needed to be typically greater than red meat additionally, due to the first closed storing subspace, therefore Multiple first closed components can be configured to one or more the second closed component supply oxygen.

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 The atmosphere of meat is stored up into hyperoxia.

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.
