Abstract
The invention relates to the method for expelling the tobacco leaf entomogenous fungi by using high-tension pulse electric field, wherein a low frequency impact with pulse amplitude of 10-15Kv/cm is applied to the tobacco leaves arranged between the electrodes, no matter unidirectional positive pulse or unidirectional negative pulse or two way pulse. Tests have shown that the invention can realize the eradication of fentomogenous fungi on the tobacco leaves.
Description
(affiliated technical field)
The invention belongs to the tobacco leaf store method, particularly high-pressure pulse electric is used to eliminate the method for tobacco leaf entomogenous fungi.
(background technology)
Tobacco is in ageing process, the time of especially natural ageing is about 3-5, because temperature, humidity adapt to bacterium and fungus breeding causes the tobacco germ to breed in a large number, the annual bag that all will turn over is removed the rotten tobacco leaf that goes rotten, and the tobacco leaf loss that causes through natural ageing on average is about 1/3rd.In order to reduce the loss, generally adopt chemical agent to come Pesticidal and sterilizing, for example, with the technology of aluminum phosphide fumigation desinsection, aluminum phosphate is met water and is generated phosphine, and phosphine has very strong Pesticidal and sterilizing ability.The shortcoming of this method is the pollution that chemical agent causes, operating personnel is taken place easily poison, and causes more harm to the smoker inevitably simultaneously.Except, the safety coefficient of aluminum phosphate itself is low, runs into air too when humidity or condensing water droplet, and the phosphine of generation also may spontaneously lead to the tobacco leaf fire.Yet, the relevant report of using the inventive method is not arranged at present as yet.
(goal of the invention)
Purpose of the present invention is intended to use the method for physics, promptly uses high-pressure pulse electric to eliminate bacterium and the fungi that tobacco leaf is had adverse effect.
(summary of the invention)
Technical method of the present invention is characterized in that tobacco leaf is placed between the electrode of electric field, and electrode is the low frequency shock pulse of 10～15Kv/cm by impulse amplitude, and the time that tobacco leaf rests between the electrode can be 25sec～3.2min.
This method can be used pulse width≤300ns, the pulse of rising edge of a pulse time≤50ns.
The selectable pulse frequency of this method is 80～160Hz.
The pulse of this method can be unidirectional positive pulse or unidirectional negative pulse, also can be bidirectional pulse.
Any object that is in the electric field all will be subjected to the effect of electric field force, and bacterium and fungi on the tobacco leaf are no exception.Bacterium and fungi sharply change with the frequency of impulse electric field along the direction of electric field force under the effect of impulse electric field power, and the result of variation is that deformation takes place for bacterium and fungi, and electric field force exceedes greatly, and deformation also exceedes severity.Reaching resonance when the frequency of the frequency of impulse electric field and bacterium and fungi itself is consistent will break up bacterium and fungi.
Calculate according to inventor's theory: square being directly proportional of electric field force and impulse electric field strength is directly proportional with the dimension size of object.Resonant frequency is the core of present technique, and it has formed the selection character of object to electric field frequency.Because different objects resonant frequency difference, so resonant frequency is difficult to seek, the present invention has selected 80～160Hz low frequency and narrow pulse, and energy frequency spectrum is comparatively even, experimental results show that to remove resmethrin.
(invention effect)
The present invention adopts physical method, pollution-free and secondary pollution, and sterilizing power is strong, and is simple to operate, safe and reliable, and power consumption is low, and power consumption 0.012 degree per ton is tested in waste water treatment, is easy to suitability for industrialized production and uses.The tobacco leaf experiment analysis results that Yunnan Inst. of Tobacco Sciences is provided illustrates: method of the present invention can be eliminated bacterium and the fungi on the tobacco leaf within a short period of time up hill and dale, and selected impulse electric field is stronger, and it is shorter that tobacco leaf is applied the time.
