Abstract
The invention belongs to food storage field is biochemical field, adopts deoxygenation in the food ambient air, reaches the purpose of food fresh-keeping.Add temperature control part to divide simultaneously and the adjustable high-temperature antistaling cabinet of development, be used with refrigerator, the food hot/cold antistaling cabinet that utilizes condenser part heat to constitute, opened up the field of food high temperature fresh-keeping, overcome the shortcoming of refrigerator-freezer, for food transportation, storage, sale provide effective new mode, bring great convenience to the human lives.Deoxidation method has many kinds, and the present invention chooses the ethanol oxygen removal by combustion, and reaction equation is a following formula.
Description
(1) the present invention is food fresh-keeping new mode and the adjustable high-temperature antistaling cabinet that adopts the method development, also can be used in combination with refrigerator, utilizes condenser for refrigerator part heat to constitute the food hot/cold antistaling cabinet.
(2) this invention belongs to food storage field and biochemical field.
(3) in the human lives, the food storage is a good problem to study always, once adopts with the salt storage the earliest, has occurred the vacuum storage afterwards, is difficult to use because of its cost is high.Because the refrigerator-freezer storage is adopted in the continuous development of Refrigeration Technique, suppresses the breeding of bacterium, but can not preserve by high temperature, has occurred the microwave insulation afterwards again.Because of its power consumption is big, and the food of being preserved is not suitable for and not seen widespread use human body, and the present invention takes to destroy one of food spoilage condition-airborne oxygen, makes oxygen become stable material.The realization means have many kinds, have chosen ethanol among the present invention as reactant, generate carbon dioxide and aqueous vapor.For preventing that ethanol from evaporating contaminated food and being provided with regenerative apparatus, food is safe from harm.Owing to destroyed the food spoilage condition, food is at high temperature preserved, opened up the frontier that high temperature is preserved food.
(4) the present invention seeks to transport a kind of efficient ways that provides for the food storage.And food is at high temperature preserved, overcome and preserved the necessary freezing shortcoming of food.The adjustable high-temperature antistaling cabinet that adopts the inventive method to develop, the food hot/cold antistaling cabinet can be provided convenience for the human lives.
(5) chosen ethanol among the present invention as reactant, the high temperature heating part adopts the electron type automatic temperature-control, with regard to chemical aspect, electric aspect, high temperature fresh-keeping cabinet, be used in combination, utilize condenser for refrigerator part heat to constitute food hot/cold antistaling cabinet principle and illustrate respectively below with refrigerator.
1, chemical aspect:
This method adopts ethanol and oxygen reaction, and it installs as accompanying drawing 1.In the container ethanol resistor wire light down with air in oxygen reaction and derive by conduit, the while, conduit was also as airborne oxygen access passage.For preventing that the ethanol volatilization from entering food, consider to be provided with cold finger, and it is led in the cabinet outer air, utilize the natural cooling of cabinet outer air that volatilization alcohol vapour device is reclaimed, be unlikely volatilization and enter in the cabinet contaminated food.Pressure is too big when preventing to burn, and the bore of conduit is bigger.Preserve as food high temperature, require the cabinet good leak tightness, prevent air admission, prevent the water vapour evaporation simultaneously.Reaction equation is
2, electric aspect
This temperature control apparatus adopts electron type, schematic diagram as shown in Figure 2, alternating current 220V is after the voltage transformer transformation, by D1, the D2 biphase rectification becomes 14 volts power supplys of direct current, as ethanol synthesis with thermal source with drive heating plate relay usefulness; Through C1, C2 becomes 7 volts of power supplys of direct current behind R3 and the Dw filtering voltage regulation again, and supplying temperature detects and amplifies power supply.Temperature detection adopts the thermally dependent resistor with negative temperature coefficient, adopts adjustable resistance to regulate temperature, R1, and R2, Rx, Rt constitutes bridge structure, controls the conducting of aerotron Q1 and end after amplifying, and reaches the purpose of A.T.C.
3, cabinet body structure:
Structure as shown in Figure 3.Adopt vertical opening door, carbon dioxide is overflowed and air admission when opening the door for minimizing, adopt the depth type, heating plate and chemical reaction regenerative apparatus are placed in the inside, the outside is provided with separate layer and is convenient to store food, and the moving door switch of the cabinet couplet on the door is with the reaction of control ethanol, and temperature control turn-knob places cabinet inside door next door, power supply, control part are put in bottom, the cabinet back side, and cold finger places the cabinet back side.
4, food hot/cold antistaling cabinet principle:
As accompanying drawing 4.Compressor is compressed into high pressure high temperature vapor through piston motion and enters high-pressure pipe after sucking the evaporator low temperature and low pressure steam.The part high-pressure pipe enters in the hot cabinet, the compressor outlet design temperature is 105 degree, steam is sent in the condenser then, the back segment of its temperature is reduced to about 55 degree, and warm highly pressurised liquid in becoming, and becomes low-temp low-pressure liquid through the capillary tub step-down again, enter evaporator absorption heat again and become the low-temp low-pressure steam, sucked by compressor once more, go round and begin again like this and finish refrigerating cycle, the utilization again of part heat.
This device only utilizes compressor outlet high pressure high temperature vapor part heat on the refrigerator basis, high-pressure pipe suitably extends, and hot cabinet mesohigh length of tube is to be advisable when not extra heating remains on 50 degree, and the refrigerator parameter is constant substantially.Hot cabinet is the same substantially with the adjustable high-temperature antistaling cabinet.Using this device to be stored in food as required is higher or lower than in the ambient temperature.
(6) evident characteristic of the present invention is directly to utilize food surrounding air, making becomes the material that food spoilage there is not influence, avoid adopting the trouble that unreactable gas brings and the difficulty of expense height and vacuum storage, and can add the temperature control part branch thus, food is stored in the high temperature, overcome the shortcoming of refrigerator-freezer, thereby the high temperature fresh-keeping cabinet of development, the food hot/cold antistaling cabinet, make food consumption convenient, really keep taste of food, be unlikely the off-flavor that food is reheated after cold, and the saving energy has practicality widely in social life.

It is less to advance to leak gas when (eight) the most handy structure of jumping of high temperature fresh-keeping cabinet total, purpose are unlatching.Its shell adopts interlayer, and the centre adds the heat-insulation and heat-preservation material, and cabinet is divided into two parts (first, second part) with separate mesh, puts heating plate in first, chemical reaction structure and regenerative apparatus.Interlayer in second is so that deposit food.Power supply, cold finger, wiring and temperature control partly are put in cabinet back (with respect to the cabinet door).Chemical composition ethanol synthesis device need be convenient to pick and place, in order to changing medicine.The cabinet door is provided with travel switch, cuts off the resistor wire of the ethanol synthesis that ignites when opening the cabinet door.
