[0025] Material drying principle and process:

[0026] The material enters the spreading machine 3 through the feed port, and is evenly spread on the upper conveyor belt by the spreading machine 3; the conveyor belt moves to the right, and the material is quickly heated by the heater, and the moisture begins to evaporate, and then falls onto the middle conveyor belt. The falling process causes the material to tumble, and the middle heater continues to heat the material on the middle conveyor belt, and the moisture continues to evaporate, and then continues to fall onto the lower conveyor belt. The upper heat exchange fan 11 then blows the upper hot air through the air duct to the material on the lower conveyor belt, so that the moisture on the material continues to evaporate, and the moisture content requirement of the material is met. When the material is passed out of the box, it is cooled by the fan and then transferred to the next process.

[0027] The material enters the paving plate 15 from the cat litter feed port 2, and the paving plate 15 reciprocates on the support frame 14 through rollers to disperse the material along the left and right sides, so as to achieve the purpose of even paving. The infrared heater 8 is not set on the lower conveyor belt 7. The hot air of the lower conveyor belt 7 is partly used for drying the material. It is transmitted from the upper conveyor belt through the heat exchange duct 9, and then rises naturally according to the principle that hot air floats, thereby realizing hot air circulation, reducing the setting of the infrared heater 8, and reducing power consumption and cost.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
