Description

Electronic chemical comprehensive fresh keeping machine for fruit and vegetable

The utility model belongs to a kind of fruit freshness preserving equipment, is specially adapted to the fresh-keeping usefulness in the fruit and vegetable depots.

Existing fruit and vegetable electronic fresh-keeping equipment, or fresh chemically equipment all is single, to killing airborne germ in the fruit and vegetable storage, absorbs ethylene gas, excess carbon dioxide, and the efficient of various pernicious gases is not high.Especially adopt single fresh chemically chemical contamination serious, therefore, there are serious problems in the equipment of preservation method of the prior art.

The purpose of this utility model is to overcome problems of the prior art, the comprehensive preservation device that a kind of electronics and chemical method combine has been proposed, its air in the fruit vegetable storage of purifying waste water effectively, kill airborne various germ, absorb ethylene gas, excess carbon dioxide and various pernicious gas, solid and liquid particle, its no chemical contamination is a kind of desirable fruit and vegetable freshness preserving equipment.

The fruit and vegetable electron chemistry comprehensive preservation device that the utility model proposed adopts static, ozone negative ions, ultraviolet ray, chemical complex art, it can various solids of absorbing and filtering and liquid particle, the waste gas that absorbs can reach 98%, ethene 95%, can also kill various microorganisms, bacterium, fungi, saccharomycete, mould, aspergillus and various virus and reach 97.74%, it really can purify air in the storehouse effectively, regulates the control fruit and vegetable and breathes, consume nutrient less, prolong fresh keeping time.

Comprehensive preservation device of the present utility model comprises electronics synthesis air purification and sterilizing device, and electron chemistry comprehensively absorbs ethene sterilizer and high voltage direct current generator.The ventilation air admission hole that the embodiment of this device has two: 1, first kind of scheme of this preservation device to be used in the storehouse is introduced air, and absorbing and filtering falls various solids and liquid particle in the air, kills various microorganisms, to purify air.It comprises airstrainer, electrostatic air cleaner, ozone negative ions generator, electric fan, air filtration film, ultraviolet germicidal lamp and shell.But above various dusts and the microorganism of 1mm in the airstrainer filtering air, electrostatic air cleaner mainly is made up of the electrion copper wire of 55 0.23X200mm and the iron plate of 10 90X234X0.35mm, the 0.4X20mm nylon wire is adopted in High-Voltage Insulation, the spacing of iron plate is 20mm, the electrion copper wire is placed in the middle of the iron plate, distance between copper wire is 15mm, and distance is 10mm between copper wire and iron plate.

The operation principle of electrostatic air cleaner wherein is: have a large amount of high voltage electricities on the copper wire, charge density is bigger, makes the copper wire discharge, cause air molecule to be ionized into a large amount of negative ions, cation is attracted by different in nature electrode, and anion is subjected to the repulsion of copper wire, is attracted by the electrode with the charges of different polarity.These ions contact with all contaminations in the air in motion process, make a large amount of electric charges on the pollutant band.Because the attraction of positive and negative charge, condense upon rapidly on the iron plate of the charges of different polarity with solid, liquid, the various microorganism of the air negative ions of a large amount of electric charges, reach the purpose that purifies air.

Electric fan wherein comprises motor, fan, electric capacity 0.9uF, 400uF and support, and the cleaned air of the electric fan of 220V, 28W after with electrostatic depuration introduced ozone negative ions generator rapidly.

Ozone negative ions generator wherein comprises 10 iron plates that 170X170X2mm is thick, be drilled with the circular hole that many diameters are 10mm thereon, the anodal copper foil plate that adopts same size, be drilled with the circular hole of 8mm thereon, pin is packed on the copper foil plate, with the alignment of two plates, the centre separates with insulation column again, and spray point and iron plate distance are about 8mm.

The operation principle of ozone negative ions generator is: since pole plate major part needle point to have higher-voltage charge density very big, produce very strong electric field nearby, when electric-field intensity reaches certain value, make point discharge, cause surrounding air ion strenuous exercise, attract generation ionization to do directed movement at needle point highfield and different in nature electrode.Various solids and liquid particle during the ozone negative ions can be eliminated and in the air kill various microorganisms, make bacterium and the mould power that loses one's life.

Air filtration film wherein is made up of the 20mm sponge, is used for air filtration.

Ultraviolet germicidal lamp wherein is with 220V, 15W wavelength 2537

Ultraviolet carries out sterilization, and it is by germicidal tube, starter, and rectifier is formed.Because 2537

Ultraviolet has very strong killing and wounding and penetration capacity, makes pathogenic microorganism generation chemical reaction, and protein coagulating sex change and death can be killed various bacteriums in the air is controlled various bacteriums, mould, saccharomycetic mycelial growth spore and germinateed; Sporogenesis limits various growth of microorganism and growth.

The shell of comprehensive preservation device adopts the iron plate of 800X290X290X0.5 to make.

2, second of this preservation device kind of embodiment comprises static absorber, electric fan, ozone negative ions generator, ultraviolet germicidal lamp and shell.Static absorber wherein comprises high-field electrode discharge silk, it is the copper wire of 35 0.23X20mm, High-Voltage Insulation diameter 0.4X20mm nylon wire, its negative pole is 10 iron plates of 0.35X90X234mm specification, be arranged with the circular hole that diameter is 6mm on the every iron plate, 5 sponges or active carbon are clipped in the middle of two iron plates with holes of whenever being separated by sponges or active carbon is of a size of 190X234X20mm, as carrier, absorb ethylene gas with potassium permanganate, every sponge aligns with the iron plate front at a distance of 5mm, put an electrion copper wire in the middle of a slice iron plate, totally 11 is first row, and second puts 4 copper wires in fifth line is separated by per two iron plates, totally 6 skies are 24, add up to 35 copper wires, distance is 20mm for 15mm iron plate spacing between the copper wire, and the spacing of iron plate and copper wire is 10mm.

Contain endogenous synthesizing ethylene at various fruit and vegetable bodies, it has hormone function, makes the fruit and vegetable precocity, fruit and vegetable is at the different times of maturation, and ethene produces the content difference, and it can make fruit and vegetable be respiratory climacteric, fruit colour change, hardness descends rapidly, the acid reduction, and soluble sugar increases, chemical reaction is accelerated, because ethene makes ripe old and feeble quickening of fruit and vegetable, as untimely discharge, fruit and vegetable is rotted very soon.

The operation principle of static chemical absorbing ethene is roughly with the electronics synthesis air purifier, only by the ethylene gas of electrostatic attraction during by a large amount of circular hole above the iron plate, accompanied with sponge or the active carbon potassium permanganate by carrier and absorbed.
