Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. As shown in FIG. 1 , the drying machine of the present invention has a drying box 30 for placing an object to be dried 34 , and a hot water circulation heating system is provided therein. The drying box 30 is connected with a condensation trapping device and a vacuum system.

[0013] The hot water circulation heating system includes a multi-layer heat-conducting aluminum plate 25 arranged in the drying box 30. The heat-conducting aluminum plate 25 is a hollow aluminum plate. 27. The eighteenth valve 18 is connected to the cooling water tank 22 and the hot water boiler 23. The heat-conducting aluminum plate 25 is insulated from the box body 30; The valve 17 is connected with the hot water boiler 23 . The cooling water tank 22 is connected with the hot water boiler 23 through the nineteenth valve 19 .

Abstract

The invention relates to a drier, for improving the drying speed and reducing crank and deformation, wherein it comprises drying bank with hot water cycle heating system; the drying bank is connected to vacuum system and condense water catcher; the drying bank contains anode and cathode for outputting electromagnetic wave power. Compared with present technique, when drying matter, the aluminum plate hot water inner circuit transmits heat to the matter, while part of its vaporized steam via vacuum pump is discharged outside the tank, and another part via condensing water catcher is discharged, then to be heated via high-frequency electromagnetic wave, to polarize the inner water molecule of matter, to quickly dry without damage.

Description

technical field [0001] The invention relates to a drying device, in particular to a dehumidifying and drying device for non-conductive objects such as bamboo, wood, agricultural by-products, paper and leather. Background technique [0002] The drying equipment in the prior art uses steam supplied by boilers, resistance heating, quartz tube heat sources, heat pumps, or direct burning of wood, coal and other heat sources to act on the object to be dried, and the heat energy reaches the inside of the object through heat transfer, and gradually transfers the moisture of the entire object to Evaporate outside. The above methods are to transfer or conduct heat from the outside of the object to the inside of the object after being heated. Often, the water on the surface of the object will evaporate first, which will cause the surface to shrink, deform and crack, especially for wood objects. For this reason, some equipment has added a regular water vapor spraying device to humidify...
