Abstract
A gas regulated refrigerator using membrane separaor of gas features that a membrane separator for nitrogen and oxygen gases is arranged on the top of refrigerator, and the gas and air in the storage of refrigerator are separated into nitrogen-enriched and oxygen-enriched gases by the membrane separator. The nitrogen-enriched gas is filled into the storage of refrigerator for making food fresh. Its advantages include simple, high reliability and no environmental pollution.
Description
The present invention relates to a kind of technology of controlled atmosphere refrigerator/refrigerator-freezer of gas film separation.It belongs to the atmosphere control technology of food fresh-keeping.
General refrigerator/refrigerator-freezer system suppresses to cause food spoilage and corrupt microbial action and enzyme effect by the environment temperature that reduces food preservation, and limits effects such as oxidation, breathing, growth and moisture distribute to a certain extent, thus the food and extend storage time.Yet along with the raising constantly of people's standard of living, also more and more higher to the quality of food requirement, not only require the food of storage not putrid and deteriorated, nutritional labeling when also requiring to keep fresh and color etc.Refrigerator/the refrigerator-freezer that like this, only has simple refrigerating function can not satisfy people's demand.For this reason, now occurred or proposed multiple fresh-keeping refrigerator/refrigerator-freezer scheme.Their way is respectively: keep suitable humidity in refrigerator/refrigerator-freezer 1.; 2. foul smell in catalytic elimination refrigerator/refrigerator-freezer; 3. the ethene that has dematuration in refrigerator/refrigerator-freezer is removed in absorption; 4. employing carbon-dioxide generator consumes oxygen in refrigerator/refrigerator-freezer and fills with carbon dioxide; 5. adopt absorption method to isolate airborne oxygen, make to be rich blanket of nitrogen state in refrigerator/refrigerator-freezer.
Purpose of the present invention is to provide the technology of controlled atmosphere refrigerator/refrigerator-freezer that a kind of gas film separates.Technology is applied to refrigerator/refrigerator-freezer according to this, refrigeration, frozen food is under the rich blanket of nitrogen state realize fresh-keeping.
In order to achieve the above object, the present invention is realized by following technical proposals.On common refrigerator/refrigerator-freezer. configuration one cover nitrogen-carrier of oxygen membrane separation device, realize being the work of rich blanket of nitrogen state in refrigerator/refrigerator-freezer storeroom, it is characterized in that, membrane separation device is by small-sized gas compressor, gas sensor, gas separation membrane assembly and valve constitute, its technical process is, the gas inlet port of compressor is by valve and refrigerator/refrigerator-freezer storeroom and outside atmosphere and logical in succession, the gas vent of compressor is connected with the membrane module lower end, the rich nitrogen outlet in membrane module upper end is communicated with refrigerator/refrigerator-freezer storeroom, the straight-through atmosphere of oxygen rich air outlet on it, gas sensor and compressor switch constitute control loop; For guaranteeing that above-mentioned membrane module has good nitrogen one oxygen stalling characteristic, membrane module can adopt the doughnut pattern, or is the sheet frame pattern, or is the coiling pattern.
Accompanying drawing is the technology of the present invention embodiment schematic diagram.Wherein 1 is storeroom, and 2 is storeroom and compressor connector, and 3 is valve, and 4 is gas compressor, and 5 is the gas film assembly, and 6 are the oxygen rich air outlet, and 7 is rich nitrogen and storeroom connected entrance, and 8 is gas sensor.
Below in conjunction with accompanying drawing the present invention is described in detail.Effect by gas sensor (8), can determine whether be in rich blanket of nitrogen state in the storeroom, if at non-rich blanket of nitrogen state, gas compressor (4) will start, gas and extraneous air in the inspiration storeroom are compressedly entered in the membrane module by compressor outlet, and the gas tunicle is separated into two strands of air-flows of rich nitrogen and oxygen enrichment, nitrogen-rich gas exports the storeroom that enters refrigerator/refrigerator-freezer from the membrane module upper end, and oxygen rich gas enters atmosphere by membrane module another outlet of upper end.Because nitrogen-rich gas constantly charges in the storeroom of refrigerator/refrigerator-freezer, the nitrogen gas concn in it constantly raises, after concentration reaches requirement, and close compressor under the effect of gas sensor, the storeroom of refrigerator/refrigerator-freezer is in the work of nitrogen-rich gas atmosphere state.Prolongation along with the working time, or the unlatching of storeroom door, after nitrogen-rich gas concentration is reduced to certain value, under the effect of gas sensor, gas compressor starts again, finishes the nitrogen process of filling of a new round, and nitrogen is filled in such circulation like this, can make refrigerator/refrigerator-freezer storeroom remain at work under the rich blanket of nitrogen state, reach the purpose of food fresh-keeping.
The invention has the advantages that: 1. device is simple, compact, reliable, economical; 2. can not contain because of fresh-keeping increasing on the food Harmful chemical; 3. harmless, free from environmental pollution.
Claims (2)
1. technology that adopts controlled atmosphere refrigerator/refrigerator-freezer that gas film separates, it is on common refrigerator/refrigerator-freezer, configuration one cover nitrogen-carrier of oxygen membrane separation device, be the work of rich blanket of nitrogen state in the storeroom of realization refrigerator/refrigerator-freezer, it is characterized in that, membrane separation device is mainly by small-sized gas compressor, gas sensor and gas separation membrane assembly and valve constitute, its technical process is, the gas inlet port of compressor is by valve and refrigerator/refrigerator-freezer storeroom and outside atmosphere and logical in succession, the gas vent of compressor and membrane module lower end join, the rich nitrogen outlet in membrane module upper end is communicated with refrigerator/refrigerator-freezer storeroom, the straight-through atmosphere of oxygen rich air outlet on it, gas sensor and compressor switch constitute control loop.
2. press the technology of the controlled atmosphere refrigerator/refrigerator-freezer of the said employing gas film separation of claim 1, it is characterized in that the membrane module in the membrane separation device can adopt the doughnut pattern, or be the sheet frame pattern, or be the coiling pattern.
