Description
Technical field
The present invention relates to a kind of dry materials equipment, particularly microwave dryer.It is applicable to the material heat drying processing of industries such as food, daily use chemicals, medicine, agricultural and processing of farm products.
Background technology
Micro-wave drying is to utilize microwave to interact with material molecule in fast-changing electromagnetic field of high frequency, is absorbed and produces fuel factor, and the inner heat that produces of material, heat drying is rapid.Therefore, more and more get more and more people's extensive concerning, and the microwave dryer of different dried materials is satisfied in exploitation.
Made in the world first micro-wave oven that be used for food heating by American's Marvin's Bake according to the heating effect of microwave as far back as nineteen forty-seven.Through after the exploration of more than ten years, successfully develop first 915MHz/50Kw tunnel type micro wave firing equipment in the world by U.S. CryodeyComporatio company in nineteen sixty-five.Subsequently, developed countries such as the U.S., Japan, Canada and Europe utilize all that the microwave energy technology solves heating in the food industry, bakes, sterilization, urge the problem of aspect such as old, and have obtained success in succession.
China is since the development seventies in 20th century, popularization microwave technology and equipment.In recent years, Application of Microwave is very rapid in the development of aspects such as food industry, chemical industry and processing of farm products.Heating using microwave, sterilization technology and equipment become better and approaching perfection day by day, and various uses, the heating using microwave of specification, the disinfection equipment of power from several Kw to hundreds of Kw emerges in an endless stream.Along with applying of microwave dryer, people are more and more higher to the performance requirement of its equipment, particularly heating uniformity, the versatility person of being to use question of common concern.
Summary of the invention
The object of the present invention is to provide a kind of microwave dryer, it can guarantee the uniformity that heats and highly versatile effectively; Simultaneously, its compact conformation, floor space is few, and material handling is convenient, is convenient to continuous production.
The present invention designs according to the principle of heating using microwave and in conjunction with the optical reflection principle.Its solution is: a kind of microwave dryer, frame is provided with the annular casing, be in it in annular cavity of more than half fan fixed head is arranged, fixed head is provided with at least 9 cover microwave waveguide device and microwave generator assemblies, the microwave waveguide device is uniform and interlace and be arranged on the fixed head, the fixed head below is the microwave drying chamber, the below in microwave drying chamber is provided with the heating whirligig, it is made up of variable-frequency motor and Heating rotary-disc, be provided with hydrofuge mechanism at the middle part of annular casing, be provided with left microwave TVS in the annular cavity of smaller part fan and in the annular casing, be, right microwave TVS and loading and unloading material district.
The microwave waveguide device is paraboloidal, Metal Ball and at least one conically shaped by paraboloidal reflector and interior setting thereof constitute, the central lines of the center line of all conically shapeds and paraboloidal reflector, Metal Ball is positioned on the center line of paraboloidal reflector, and the microwave generator in the microwave generator assembly is positioned on the focus of paraboloidal reflector.
Two described conically shapeds that vary in size are arranged in the paraboloidal reflector.
The present invention mainly is that frame is provided with the annular casing, be provided with microwave generator assembly and microwave waveguide device in this casing, they are the annular shape of fan and arrange, uniform and interlace and be arranged on the fixed head, and the heating whirligig is arranged on the below in microwave drying chamber, also is provided with left and right microwave TVS and loading and unloading material district in the annular casing.Because the overall structure of this equipment is annular, compact conformation not only, floor space is little, and material handling is convenient, is convenient to continuous production.Because the heating whirligig is driven by variable-frequency motor, its rotating speed can be adjusted arbitrarily as required to satisfy the dry needs of different material.Because the coupling aperture of microwave waveguide device is uniform and interlace and be arranged on the fixed head, and the coupling in the microwave drying chamber is in the feeble field district of pattern high electric area that need excite and the spurious mode that may exist, form annular complement mode, make standing-wave ratio numerical value little, can guarantee the microwave generator working stability, and can make the microwave drying chamber that more pattern is arranged, the coupling aperture and the electromagnetic field that help microwave drying chamber internal schema are evenly distributed, to guarantee the uniformity of microwave.Moreover, the design of paraboloidal reflector because of the microwave waveguide device that is paraboloidal, be not only according to the optical reflection principle, effect by speculum accumulates in the luminous flux of spot light radiation in the limited solid angle, and producing very high luminous intensity, the paraboloid of revolution through speculum is reflected into spot light the light shape with definite shape and intensity again.Adopt compound parabolic concentrator (CPC), CPC is a kind of non-imaging type solar concentrator, and it is based on a kind of concentrator of edge optical principle design, to the ripple of oblique incidence also can be parallel reflection.People such as Winston, Rabl has studied the optical property of the CPC with ideal mirror reflecting surface, people such as Bassett, Derrick and Georlette have analyzed the heat collector that difform perfect reflecting diffuser and desirable reflection-absorption body constitute from probability statistics.Therefore, paraboloidal microwave waveguide device can not only reflect the microwave of straight incident, can also carry out reflected in parallel to the microwave of oblique incidence, thereby microwave is as much as possible evenly distributed, and improves the uniformity of heating effectively.Owing in the paraboloidal reflector, be provided with conically shaped and Metal Ball, can carry out diffuse reflection to the microwave that arrives on it, thereby it is more even that microwave is distributed, and can prevent that microwave reflection from damaging the microwave source place, thereby can guarantee the service life of microwave generator, and highly versatile.
