Description
The present invention relates to a kind of food freshness-keeping box.Particularly relate to food freshness-keeping box a kind of not power consumption, deoxygenation chemically.
Refrigerator or the freezer that extensively adopts is to adopt refrigerating plant that refrigerator or refrigeration storehouse temperature are descended now, makes food freezing, prevents that it from rotting, and reaches the purpose of longer-term preservation.This just needs consumed power, not only need spend the electricity charge in use, and can't use at the wide geographic area of short of electricity.Because food through freezing, can form the cell liquid ice crystal in it, thereby change the food freshness, also is a big shortcoming.
Task of the present invention is to provide a kind of food freshness-keeping box, and it does not need electric consumption, and food need not again to prevent to rot and can reach through freezing, also keeps the purpose of original delicate flavour.
For realizing the foregoing invention task, food freshness-keeping box of the present invention includes casing, chamber door and is fixed in the interior grid food-shelf of described casing etc., its characteristics are to be unworthy of preparing device for cooling, and generation with chemical method remove in the casing in the air oxygenous chemical processing device.Because anoxic in the casing makes food be in anticorrosion safe condition, can not become morally degenerate, and be reached the purpose of longer-term preservation by bacterium.
The chemical method of known deoxygenation is a lot, in order to reduce the cost of use of antistaling box as much as possible, can adopt the method for burning earlier, remove exhausted most oxygen in the casing, and then play oxidation with the iron end and eliminate remaining minor amounts of oxygen, being used in combination of these two kinds of methods just can drop to the air oxygen content in the casing required utmost point low degree.
Below in conjunction with accompanying drawing embodiment of the present invention and basic principle are described in further detail.
Fig. 1 is the front view of the present invention's's " food freshness-keeping box " preferred plan.
Fig. 2 is the oxygen removal by combustion schematic diagram of device of the present invention's " food freshness-keeping box " preferred plan.
Fig. 3 is the schematic diagram of timer used in the oxygen removal by combustion device.
Referring to Fig. 1 and Fig. 2, food freshness-keeping box of the present invention comprises a casing (1), chamber door (2), grid food-shelf (3), oxygen removal by combustion device (4) and iron end oxidation deaerating plant (5).Described oxygen removal by combustion device (4) can be placed in the casing, also can settle casing outer (this diagram is placed in the outer rear of casing), it comprises a storage fuel (light oil that is easy to light, alcohol preferably) fuel tank (6), combustion chamber (7), be placed in the efficent electronic lighter ignition tip (9) (can buy on the market) of interior fuel nozzle (8) in described combustion chamber (7) and close nozzle, fuel is transported to the fuel-supply pipe (10) of fuel nozzle (8) from fuel tank (6), be placed in the fuel cock (11) in the fuel-supply pipe (10) and (7) outlet passes to casing (1) top from the combustion chamber pulls out airduct (12), the bottom of casing (1) is connected in the import of combustion chamber (7).Refractory brick combustion chamber (13) is housed in combustion chamber (7), and fuel-supply pipe (10) earlier passes to fuel nozzle (8) in refractory brick combustion chamber (13) inside turn after a few, in refractory brick combustion chamber exit flame stabilization piece (14) is housed.Outside pulling out airduct (12), be with cooling water pipe (15), water in the cooling water pipe.Like this, fuel comes out to be lighted by igniter to the fuel nozzle ejection through fuel-supply pipe from fuel tank, spiral and pre-heating fuel in combustion chamber owing to fuel-supply pipe later on, make it vaporization, and burn away, the air in the casing constantly is drawn into the combustion chamber by the bottom aspirating hole and participates in burning, and burning is after pull out the top that enters casing after airduct is cooled, so continuous circulation, and burn the oxygen of the overwhelming majority (about 90%) in the case.Because the gas after the burning is through cooling, temperature rise is no more than 5 ℃ in the casing.
In order to guarantee that the fuel in the fuel tank can supply fuel from the trend nozzle effectively, on fuel tank (6), pressue device is housed, this pressue device comprises a pressurized cylinder (16), place the piston (17) in the pressurized cylinder (16), be placed in the one-way cock (18) in pressurized cylinder (16) exit, pass to the appendix (19) of fuel tank (6) from the pressurized cylinder outlet, be connected in pushing away gas handle (20) and being placed in the spring (21) that pushes away under the gas handle (20) of piston (17), pushing away the lever (22) that the arrangement of gas handle outer end a distance affects fuel cock (11), the port of export in pressurized cylinder (16) is equipped with timer (23), and what control efficent electronic lighter ignition tip (9) was housed in the end by pushing away gas handle (20) of pressurized cylinder (16) often drives electric shock switch (24).Like this, when chamber door (2) when shutting, the handle of chamber door (30) pushes away gas handle (20) fuel tank (6) is inflated, and simultaneously closes and often drives electric shock switch (24), ignition tip (9) igniting by pushing away the gas handle, take fire, handle (30) half-twist, release pushes away gas handle (20), and then it is under the rebound effect of spring (21), make piston (17) return movement, its movement velocity is controlled by timer (23).The structural principle of timer as shown in Figure 3.Chamber door (2) is shut each time, and the inflate quantity and the supplied fuel of pressurized cylinder adapt, the just in time flammable oxygen of burning the overwhelming majority (about 90%) in the casing, after supplying fuel to stop, burning finishes automatically, and system returns to original state, waits for that chamber door is closed Shi Zaihang work for the second time.
Because all oxygen in the casing can not be all removed in burning, so in casing, settle iron end oxidation deaerating plant (5).Referring to Fig. 1, iron end oxidation deaerating plant (5) comprises a water pond (25) of containing water storage, cover sponge (26) on the water pond (25), cover the brown paper (27) on the sponge (26) and be dispersed in iron end (28) on the brown paper (27).This iron end oxidation deaerating plant is fixed in the inner chamber top of casing (1) by back-up block (29), and an iron end oxidation deaerating plant (5) also respectively is housed under each grid food-shelf (3).Like this, the oxidation owing to the iron end absorbs remaining oxygen in the casing.Owing to need moisture content in the oxidizing process of iron end,, by the sponge support so the iron end is placed in the water pond of water.In order to quicken iron end oxidizing process, iron adds carbon dust in the end, and the effect of carbon dust is: 1. iron carbon electrification number of pole-pairs is increased; 2. prevent that iron oxide from hardening; 3. water guide effect allows reaction that enough moisture content is arranged, because the chemistry of iron is active, can make the oxygen content in the casing reduce to utmost point low degree very soon, makes food be in safe anticorrosion state.Water in the water pond should add a small amount of villaumite, as salt, and keeps water level.
Can also be with other chemical method deoxygenations, as absorbing oxygen with sulfite solution and hydroxide ferrous solution.Though these methods are also simple, price is more expensive.
In addition, cooling water pipe (15) planted agent adds the water of capacity, at severe cold season, should add impurity such as salt, forms anti-icing solution.Can hang some activated carbon or stem tea bag (33) at the case internal upper part, gas humidity in smell that absorbing food product evaporates and the reduction case.The caulking gum (34) that should settle sealing gland to use on the contacted frame of casing and chamber door, casing top air inlet (31) and bottom bleeding point (32) all should be adorned filter screen.
The volume of antistaling box can be designed to any size on demand, also can be designed to fresh-keeping warehouse.According to experiment, by 150 liter volume calculations, each unpacking consumes alcohol 10～15 grams, about 50 grams in iron end.Eliminate the time of residual oxygen and the quality and the area at iron end and be directly proportional about about one hour.
After deoxygenation was handled, gas mainly was nitrogen, carbon dioxide, small amounts of inert gas and steam in the case, energy suppression microbicide and mushroom, and also do not have the pernicious gas contaminated food.
With after the iron end, be oxidized to iron oxide Fe
2O
3(XH
2O), should be by usefulness again after producer's recycling of producing antistaling box, its processing method is as follows: with the iron oxide oven dry, heating feeds carbon monoxide in sealed furnace more earlier, and making iron oxide reduction is iron, emits carbon dioxide.Its temperature should be controlled at below 500 ℃, unlikely generation cementite.
