Abstract
The invention discloses a device for killing worms or ova in crops by electromagnetic waves, comprising a metal pipe, an insulating dielectric pipe and a plurality of microwave sources. The metal pipe is provided with a plurality of microwave filling openings where the microware sources are arranged. The insulating dielectric pipe is arranged inside the metal pipe, one end of the insulating dielectric pipe is connected with a crop feeding end and the other end is connected with a crop discharging end. Microwaves of the microwave sources are introduced into the metal pipe through the microwave filling openings and used for irradiating the insulating dielectric pipe so that the crops inside the insulating dielectric pipe are heated. Different heating effects can be achieved by utilizing different water contents of the worms or ova in the crops, furthermore, the final aim of killing the worms or ova in the crops is achieved, and the quality of the crops is maintained.
Description
Technical field
The present invention relates to a kind of electromagnetic wave and eliminate the device of interior worm of crops or worm's ovum.
Background technology
Crops such as rice, wheat must effectively be controlled the generation of worm or worm's ovum, or eliminate worm and worm's ovum fully before encapsulation or storing, and make these crops have the long pot-life, and keep good quality.General tradition is to use methods such as hot blast, electric heating, steam, and it all is to utilize principles such as heat conduction, convection current to import heat into crops inside from the outside, and the incremental crops central temperature that makes raises, and then reaches the purpose of eliminating worm and worm's ovum with high temperature.But the hot transmission method of this kind is high-energy source consumption, and the required working time is very long, and does not meet economic benefit.Moreover the mean temperature of the hot transmission method of this kind is wayward, and heat time heating time is long, therefore, reduce the moisture that retains in the crops easily, and then the destruction crops should have quality.
Summary of the invention
The present invention proposes the device that a kind of electromagnetic wave is eliminated interior worm of crops or worm's ovum, and it comprises a metal tube, an insulation dielectric pipe and a plurality of microwave source.This metal tube is provided with a plurality of microwave inlets, is the position of microwave source installing.This insulation dielectric pipe is located at this metal tube inside, and the one end connects the crops feed end, and the other end connects the crops discharge end.Microwave from microwave source imports metal tube inside through the microwave hand-hole, this insulation dielectric pipe inside is shone, and then produced the effect of Fast Heating.And when these crops were arrived at this crops discharge end, worm that these crops are contained or worm's ovum were killed by the irradiation of this microwave source.
Wherein, the diameter of this metal tube or the length of side are less than or equal to the wavelength of three times of these microwave sources.
Wherein, the caliber of this insulation dielectric pipe is less than 1/2nd of this microwave source wavelength.
Wherein, this microwave inlet is with axle or in the face of claiming that branch is arranged at this metal tube.
Wherein, the material of this insulation dielectric pipe is an ambroin.
Wherein, the material of this insulation dielectric pipe is a glass.
Wherein, the material of this insulation dielectric pipe is a pottery.
Adopt electromagnetic wave of the present invention to eliminate the device of interior worm of crops or worm's ovum, crops are via the crops feed end, enter in this insulation dielectric pipe, when passing through the insulation dielectric pipe inside of microwave irradiation fast, these crops can be by this heating using microwave to one specified temp (50 ℃～70 ℃), and then reach the final purpose that high efficiency is eliminated worm in these crops or worm's ovum.Be less than about 20% as the moisture content of crops such as rice, wheat, and the moisture content of worm or worm's ovum is usually greater than 60%, therefore, when with microwave crops being shone, worm or worm's ovum be because of heating up fast, and cause death.Since heating using microwave have speed fast, meet economic benefit, thermal efficiency advantages of higher, and control required temperature easily, usually the highest temperature is controlled at less than 70 ℃, thus can directly not exert an influence to crops, and then improve the quality of crops and prolong the pot-life.

Embodiment
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is one of apparatus of the present invention schematic diagram, and Fig. 2 is two of apparatus of the present invention schematic diagram.The present invention comprises a metal tube 10, an insulation dielectric pipe 20, a plurality of microwave source 30.Metal tube 10 is provided with a plurality of microwave inlets 11, is the position of microwave source 30 installings.Insulation dielectric pipe 20 is located at metal tube 10 inside, and the one end connects crops feed end 50, and the other end connects crops discharge end 60.
Microwave from microwave source 30 injects importing metal tube 10 inside, 11 holes through microwave, insulation dielectric pipe 20 is shone, and then produce the effect of heating.Therefore, crops 40 enter in the insulation dielectric pipe 20 via crops feed end 50, when passing through insulation dielectric pipe 20 inside of microwave irradiation fast, crops 40 can be by heating using microwave to one specified temp (50 ℃～70 ℃), when crops 40 were arrived at crops discharge end 60, contained worm or worm's ovum were caused biological tissue's function to destroy by temperature and the highfield that microwave irradiation produced in the crops 40.Be less than about 20% as the moisture content of crops such as rice, wheat, and the moisture content of worm or worm's ovum is usually greater than 60%, therefore, when with microwave crops 40 being shone, worm or worm's ovum be because of heating up fast, and cause death.
Fig. 3 A, Fig. 3 B, Fig. 3 C and Fig. 3 D are the schematic diagram of the relative position of metal tube, insulation dielectric pipe and microwave inlet.Fig. 3 A, 3B and Fig. 3 C, 3D are respectively circular and square metal tube 10, and microwave inlet 11 is arranged at metal tube 10 with axle or in the face of claiming to distribute.
Brought forward is stated, and the best design parameter through testing acquisition metal tube 10 and insulation dielectric pipe 20 is that the diameter or the length of side of metal tube 10 need be less than or equal to three times of microwave source wavelength, and insulation dielectric pipe 20 is less than 1/2nd of the microwave source wavelength.For example, when microwave source was 2.45GHZ, its wavelength was 12.24 centimeters, so the diameter of insulation dielectric pipe 20 needs little 6.1 centimeters, and the diameter of round metal tube 10 needs less than 36.7 centimeters, and again, the length of side of square metal tube 10 needs little 36.7 centimeters.Insulation dielectric pipe 20 is made by the insulation material, as plastics, glass or pottery etc.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
