Description

Comprehension preservation machine for fruit or vegetables with electronic and chemical method

This utility model belongs to a kind of fruit freshness preserving equipment, particularly in the electron chemistry comprehensive preservation equipment of fruit and vegetable.

Existing fruit and vegetable electronic fresh-keeping equipment, or Chemical Preservative Method of Fruits is single fresh-keeping mode, to killing airborne pathogenic bacteria in the fruit and vegetable storage, absorbs ethylene gas, excess carbon dioxide, and the efficient of various harmful gass is not high.It is fresh-keeping particularly to adopt simple chemical method that fruit and vegetable is carried out, and chemical contamination is serious, and therefore, above-mentioned fresh-keeping effect is extremely undesirable.

The purpose of this utility model is exactly to have proposed a kind of fruit and vegetable electron chemistry comprehensive preservation equipment at the shortcoming that exists in the prior art, its air in the fruit vegetable storage of purifying waste water effectively, kill airborne various pathogenic bacteria, absorb ethylene gas, excess carbon dioxide, and all kinds of harmful gass, solid and liquid particle, and its no chemical contamination, very easily promote the use of a kind of really quite desirable, high-efficiency reliable fruit and vegetable freshness preserving equipment.

In order to realize the purpose of this utility model, the electron chemistry comprehensive preservation machine that is proposed comprises a hard plastic shell, static chemical absorbing device, electric fan, ozone negative ions generator, ultraviolet sterilization apparatus, the chemical molecular filter membrane is formed, air in the fruit and vegetable storage, introduced the electrochemistry absorption plant by electric fan, this device comprises iron plate or other sheet metal that the 8-10 sheet 0.35mm left and right sides is thick, be drilled with a large amount of diameters thereon and be the circular hole about 2.5mm, accompanying in the middle of the circular hole about the thick 20mm of 3-8 sheet by activated carbon is carrier, be mixed with potassium permanganate and be processed into flaky Solid-state Chemistry absorbing film, by sheet metal, the chemical absorbing film is a discharge electrode, be arranged with a large amount of diameters and be the copper wire about 0.35mm in the middle of two iron plates, wherein corona wire is anodal for discharge.Because the discharge copper wire has high direct voltage positive electricity, iron plate, during chemical absorbing film band high direct voltage negative electricity, the voltage height, electric field intensity makes the copper wire discharge of band high direct voltage positive electricity, cause near the air of copper wire to be ionized, produce the directed ion wind that flows to negative pole by positive pole, cation moves to negative pole rapidly, make pathogenic bacteria in the air, ethylene gas, excess carbon dioxide, various harmful gass, solid and liquid particle are by static chemical absorbing device, cation is bumped against to be ionized, they are become positively charged, rapidly by the iron plate circular hole, attached being bonded on the chemical absorbing film of condensing, and by on the film with negative electricity neutralized, become neutral gas and particle.Because activated carbon adsorption power is strong, potassium permanganate absorbs ethylene, and they combine and can kill various pathogenic bacterias effectively, absorbs ethylene gas, and excess carbon dioxide and harmful gas, solid and liquid particle are to reach the effect fresh-keeping to various fruit and vegetables.

Embodiment to comprehensive preservation equipment of the present utility model is further described below with reference to accompanying drawings, and its accompanying drawing has:

Fig. 1 is the longitudinal sectional drawing of comprehensive preservation equipment of the present utility model;

Fig. 2 is the front section view of the static chemical absorbing device in the equipment shown in Fig. 1.

In Fig. 1,1 has mechanical strength, a moisture-proof, antiseptical shell for making with the thick duroplasts of 3mm; 2 is the electrion copper wire, be installed in the middle of two iron plates 4, distance between iron plate 4 and the copper wire 2 is roughly 10mm, discharge copper wire 2 has 6 groups of (see figure 2)s, but also can increase and reduce, and every group is generally 8, totally 48, connect with lead, adopt the high-voltage power supply line to be connected with ozone negative ions generator 9 positive poles, by diameter be about 8mm, the ceramic insulating tube 8 that is about 25mm passes body fuselage 1 and a direct current 12KV high-voltage power cathode is connected.Discharge copper wire 2 is separately fixed at up and down on the ceramic insulation thing 3, and this insulant is that long approximately 20mm is separately fixed at casing 1 inboard (see figure 2) about diameter 5mm.Totally 10 of iron plates about the thick 0.35mm shown in Fig. 2, being drilled with a large amount of diameters on every iron plate is the circular hole 5 of 2.5mm, is beneficial to air and passes through.Distance between the iron plate 4 is 20mm, two ends are separately fixed at casing 1 inboard, accompanying 5 20 millimeters thick every the centre of two iron plates 4 is that carrier is mixed with potassium permanganate and is processed into flaky Solid-state Chemistry absorbing film 6 by activated carbon, the electric wire that iron plate 4 adopts diameter to be about 0.5mm is connected with the negative pole of ozone negative ions generator 9, footpath ceramic insulating tube 12 passes shell 1, this insulation tube is about 25mm, diameter is about 8mm, be connected with a DC high-voltage power supply negative pole, electric fan 7 is installed in static chemical absorbing device back, be fixed on shell 1 inboard, the electric fan running voltage is the 220V alternating current, power is 35W(watt), be used for air in the storage is introduced in the fruit and vegetable fresh-keeping device.

Ozone negative ions generator 9 is installed in the back of electric fan 7, is fixed on casing 1 inboard.The ozone negative ions can neutralization of ethylene gas, have the function of killing pathogenic bacteria, ultraviolet sterilization apparatus 10 comprises Burdick lamp 10, it is installed in ozone negative ions generator 9 back, and is fixed on casing 1 inboard.The running voltage of ultraviolet germicidal lamp 10 is the 220V alternating current, and power is 30W, wavelength 2537
