Description

Electronic fresh-keeping machine for fruits and vegetables

The utility model belongs to preserving fruit and vegetable utilizing equipment, is used for fruit, vegetables are fresh-keeping, also can be used for material mildew-resistant such as grain, food, medicinal material, tobacco, the anti-processing of damaging by worms.

Existing fruit vegetables storing, preservation method has freezing, controlled atmosphere, chemical preservation medicament etc., there is certain shortcoming in these methods, for example: freezing and controlled atmosphere method, investment is big, the energy consumption height, the chemical preservation medicament exists the resistance to the action of a drug and residual hazard harm, local flavor is not just, the width of cloth is penetrated fresh-keeping and vacuum freshness retaining method and is had shortcomings such as radioactive pollution environment and maintenance cost height respectively, and therefore, the seventies rises utilizes ozone that atmospherical discharges produces and just, the preservation method of anion, owing to have nontoxic, free from environmental pollution, advantages such as energy savings are subjected to generally paying attention to, the relevant report of this respect has: US923505, Japan's special permission communique and 56-36912, China patent CN86101706, the patent of ion generator has the CN85201695 of China etc.In the prior art; produce ozone and just; the air discharge chamber of anion comprises air voltolising electrode and corona discharge electrode; the voltolising electrode form has plate electrode; the employing mesh electrode is also arranged; and mesh electrode is placed in the insulation tubes such as glass; this structure is more outmoded; fragile; the inconvenience transportation, and discharging efficiency is low, and turbulent condition is also not ideal; therefore; be necessary electrode structure and arc chamber structure are made improvements, in addition, the control section of existing fresh-keeping device mostly adopts mechanical type; on-load is difficult for down regulating, and does not also have safety guard and air-flow circulation discharge process function etc.

The purpose of this utility model provides a kind of component and the concentration that can regulate discharge gas under running status, and is safe and reliable, discharging generating gas productive rate height, preserving fruit and vegetable utilizing machine capacious.

The utility model adopts following version to achieve the above object: the basic structure form is two kinds: a kind of: fresh-keeping device comprises: can give and put digital Displaying timer device, the duty control circuit, blower fan, H.V. step up transformer, the high-voltage rectifying loop, the safety guarantee circuit, the combined discharge chamber, air-flow circulation annex, said combined discharge chamber comprises: square shell, the two ends of shell have air inlet pipe respectively, escape pipe, be placed with annular needle-like high-effect ionic emitter stage in the pipe of escape pipe, the inside of housing is placed with one group or two groups by multi-layer sheet, the netted voltolising electrode of alternately arranging, the mesh electrode that each plate electrode and plate electrode are adjacent all is sealed in the dielectric layer of expoxy glass silk fabric board and high-dielectric coefficient bonding filler formation, adjacent panels, be lined with medium strip at longitudinal edge between the dielectric layer of mesh electrode, in order to decision arc chamber size, constitute the cell discharge chamber, the power supply lead wire epoxy sealing.

In the another kind of version, replaced original blower fan with fan, shell has adopted circular configuration, two ends at round tube, dress fan in the pipe of one end, adorn annular needle-like high-effect ionic emitter stage in the pipe of the other end, air-flow circulation annex is not installed in this structure, remaining part is identical with first kind of structure.

First kind of structure, blast is big, second kind of structure, blast is little, can elect according to handling object.

The utility model advantage is: adopt electronic device to come adjustments of gas component and concentration, and easy to operate; Have the safety guarantee circuit, but attended operation personnel's personal safety; Electrode uses plate, netted alternately arrangement architecture, firm in structure, be convenient to use in transportation and the way, take the vertical mutually and air-flow circulation discharge in the plane of two groups of electrodes to wait measure, can enlarge the capacity of machine and the productive rate of raising discharging generating gas.
