When the cylinder 205 rotates, it drives the multiple sets of rod bodies 210 therein to move, so that the multiple sets of rod bodies 210 between the cylinder 205 and the second tank 201 cooperate to crush the corn cobs. The crushed corn cobs fall downward and mix with the crushed raw materials, and then the corn cobs are crushed again by the rolling device, so as to improve the size consistency of different raw materials and improve the uniform drying effect of different raw materials. The cut, crushed and crushed different raw materials fall to the top of the second screen plate 305, and the support shaft 301 is driven to rotate by the driving device, so that the support shaft 301 drives the kit 302 to rotate, so that the multiple groups of rollers 303 move circumferentially, and at the same time the power device drives the second screen plate 305 to rotate, so that the rollers 303 and the second screen plate 305 cooperate to crush the corn cobs again, and the crushed corn cobs and other raw materials fall downward, so as to improve the uniform crushing size effect of different raw materials and improve the crushing efficiency of raw materials. When the multiple groups of rollers 303 pass through the top of the multiple groups of protrusions 306, the multiple groups of protrusions 306 drive the second screen plate 305 to vibrate up and down, so that the second screen plate 305 vibrates and screens the raw materials, reduces the deposition of the crushed raw materials on the top of the second screen plate 305, and improves the crushing efficiency of the raw materials.

[0045] like Figures 1 to 12 As shown, a raw material drying processor for furfural production of the present invention, when working, puts agricultural waste materials such as rice husks, corn cobs, wheat bran, etc. into a crushing device, and the crushing device crushes the raw materials of different sizes into a uniform size. At the same time, the crushing device preheats the raw materials during the crushing process, and then the crushed raw materials are lifted and transported to the inside of the first tank body 101 by the auger 106. The raw materials entering the first tank body 101 fall to the top of the filter screen 103. After the raw materials enter the first tank body 101, the closing valve 107 is closed and the filter device is opened. By turning on the hot air blower 105, hot air is blown into the air inlet hood 104, so that the hot air passes through the filter screen 103 and blows toward the surface of the raw materials, so that the raw materials are constantly up and down under the action of wind force, reducing the adhesion between the raw materials that affects the drying uniformity, and the hot air dries the raw materials, and then they are discharged by passing through the filter device.

[0046] The main functions achieved by the present invention are: by making the raw materials fluctuate continuously under the action of wind force, the adhesion between the raw materials is reduced to affect the drying uniformity;

[0047] By crushing raw materials of different sizes into a uniform size, the drying uniformity of various raw materials is improved, and the quality of subsequent furfural production is improved.

[0048] The hot air blower 105, auger 106, electric heating plate 402, first motor 403, reducer 503, second motor 504, cylinder 704, third motor 801 and agitator 1001 of a raw material drying processor for furfural production of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
