Description
Technical field
The present invention relates to a kind of multifunction air-conditioning refrigeration freshness retaining system of air refrigeration, belong to the controlled atmosphere cold storage preservation technique.
Background technology
People will eat food earning a bare living every day, these food sources, and summarizing to get up is exactly five cereals, fish, meat, fowl, egg, milk, oil, salt, sauce, vinegar, tea etc.These foods must be consumed to people's dining table on the ability through links such as production, storage, processing, transportation, sale.In for a long time storage, processing, transportation, sales process, unavoidably can go bad, spoiled, variable color, even rottenly rot, can not eat fully.According to incompletely statistics, the whole nation is annual to account for more than 20% of output because of about 8,000 ten thousand tons of the rotten fruits and vegetables that rot, and can eat 1 year for 200,000,000 people, and its economic loss is more than 7,500 hundred million yuan.Also more than tens million of tons, its loss is surprising to the annual grain that decreases because of ageing, storehouse in the whole nation.
Therefore, people are in order to reduce or to save its loss, and it is fresh-keeping also to have taked thousand and one way.Wherein using the most general preservation method has following several: as freeze preservation, ozone sterilization is fresh-keeping, the deoxygenation controlled atmosphere, and inflated with nitrogen is transferred fresh-keeping, the filling CO 2 controlled atmosphere, deepfreeze is fresh-keeping, and it is fresh-keeping to add anticorrisive agent, vacuum freshness retaining, it is cured fresh-keeping to salt down, or the like.These are the preservation method of usefulness, has obtained certain effect, reduces and has saved partial loss, still, all has its weak point to be:
(1) freeze preservation.The history that its method is used is the longest, remains one of important preservation method now.Its weak point is: the one, and the energy consumption height.The temperature design of the general storehouse of freezer should remain on about-15 ℃ between-25 ℃～-30 ℃, and relative humidity is between 95～98%.In freezing process, whenever freeze one ton of meat, need power consumption 60～80 degree, the storehouse temperature is low more, and energy consumption is big more, and fresh-keeping cost is high more.The 2nd, fresh-keeping of poor quality.Owing to freeze, the water in the biological cell is frozen into ice, makes membranolysis, though can preserve without putrefaction for a long time, meat is rotten, variable color, spoiled, has reduced edibility.So frozen meat, frozen fish, the price of freezing fowl etc. are more cheap than fresh, producer's loss is big, is not subjected to consumer's welcome again.Owing to freeze, food dries out, and is easily shrivelled, weight saving, and the storehouse is decreased big.The 3rd, microorganism, bacterium are not freezed to death, and are temporary transient dormancy, treat temperature raise thaw after, they can be come back to life again, the harm people's is healthy.Also have, build the freezer investment greatly, in freezer huge evaporation tubes will be installed, only this will increase a lot of investments.Though it is fresh-keeping that freezer also can be used for deepfreeze, because the storehouse temperature is inhomogeneous, temperature is controlled and " is frozen fruits and vegetables ripe " easily when bad, and when freezing the fruits and vegetables outbound ripe, it is very fresh that appearance seems, but spoiled when edible, outbound is just turned black soon, and mashed sooner.
(2) ozone sterilization is fresh-keeping.Because fresh-keeping cost is low, use also very generally, but weak point is: owing to ozone-air diffuses flow in the storehouse is very slow, ozone concentration is inhomogeneous, and sterilization is prone to " dead angle ", also can cause damage.
(3) coke molecule sieve series nitrogen is transferred fresh-keeping device (or oxygen permeable membrane nitrogen making machine).Nitrogen charges in the storehouse, certain preservation is also arranged, but weak point is: can not reduce the storehouse temperature, grain easily goes mouldy.Mainly be owing to contain moisture in the grain, the south of the lower reaches of the Yangtze River particularly, the grain of the intermittent drizzles in the rainy season summer harvest in season because moisture is arranged, makes the grain fermentation, storehouse temperature rise, the quickening of going mouldy.Though falling the storehouse teds and also can alleviate grain and go mouldy, and needs to drop into great amount of manpower and broad place is provided.And time one is long, and grain also can generate heat and go mouldy, and turns over the storehouse again and falls the storehouse and dry.Though the large granary that has is furnished with the window air conditioner cooling, the big grain depot for more than one hundred million jin still can not tackle the problem at its root.
(4) there is not the deepfreeze fresh-keeping warehouse of ozone sterilization.Also very general in the use, but weak point is: only be that deepfreeze is fresh-keeping, still can't resolve and go mouldy.Facts have proved that in the low temperature environment about 5 ℃, mold propagates is also very fast.The easy moldy metamorphism of cold compartment of refrigerator is exactly this reason.
(5) adding anticorrisive agent in the food, also is to use more preservation method, though also can temporarily reach fresh-keeping purpose, weak point is: no matter use which type of chemical addition agent, all unavoidably produce secondary pollution.Because chemical substance is present in the food, can slow poisoning after people are edible.The additive that has also can cause the people in desperately as formaldehyde (being commonly called as sodium formaldehyde sulfoxylate).
(6) use the oxygen scavenger controlled atmosphere.Also widely use, but weak point is: the dried food and nuts for inner wrapping still has effect as mushroom, auricularia auriculajudae etc., but is not suitable for the fresh-keeping of large-scale provision store.
(7) vacuum freshness retaining.Also be to use more method, for not producing the food of gas after the packing, a spot of inner wrapping still has fresh-keeping effect, but weak point is: for the food that can produce gas after the packing, just can not use this method, because it can destroy vacuum the packing back.The fresh-keeping of large food just can't be used.
