The shell 200 is in a way of being higher on the left and lower on the right and is fixed to the top of the outer wall of the main body base 100 through a pad. The transmission component is arranged at a high position of the shell 200;
[0021] The transmission component includes a reducer 110, the bottom end of the outer wall of the reducer 110 is fixed to one side of the top of the outer wall of the main engine base 100 through a support, the top input shaft of the reducer 110 is installed with a motor 130, and the outer wall of the reducer 110 and the side away from the shell 200 are installed with a protective cover 120. The motor 130 can drive the reducer 110 to rotate after power is turned on, and the reducer 110 can reduce the speed output by the motor 130 and increase the torque, and then drive the stirring component to rotate through the output shaft and the coupling 140. The stirring component includes a stirring shaft 230, both ends of the stirring shaft 230 are rotatably connected to both sides of the inner wall of the end cover 210, the side output end of the reducer 110 is fixed with a coupling 140, and the end cover 210 close to the coupling 140 is installed with a bearing seat 150, and the end of the coupling 140 away from the reducer 110 is connected to the side end of the stirring shaft 230 through the bearing seat 150, and the outer wall of the stirring shaft 230 is fixed There are paddles 240, and multiple paddles 240 are evenly arranged in a circular array. The stirring shaft 230 and the paddles 240 are connected. The stirring shaft 230 is set to drive the paddles 240 to rotate so that the paddles 240 can stir the granular material, and to transport the heat medium into the paddles 240 so that the paddles 240 can heat the granular material through the side end surface. Both sides of the outer wall of the paddle 240 are inclined toward the end away from the stirring shaft 230. The outer wall of the paddle 240 and the end away from the stirring shaft 230 are fixed with scrapers 241, and the outer walls of the scrapers 241 are in contact with the inner wall of the shell 200. The paddle 240 is in the shape of a wedge-shaped hollow semicircle, through which the heat medium can be passed. In addition to stirring, it is also a heat transfer body. The two main heat transfer side surfaces of the paddle 240 are inclined, so when the material contacts the inclined surface, as the blade rotates, the particles quickly slide away from the inclined surface, so that the heat transfer surface is continuously updated, thereby enhancing the heat transfer. A scraper 241 is arranged on the outside of the paddle 240 to scrape up the material deposited on the bottom of the shell to prevent dead corners. A feed port 220 is connected to the top of the outer wall of the shell 200 and the side located at a high position.

[0024] At the same time, due to the special structure of the paddle 240, the granular material is alternately squeezed and relaxed during the drying process, which strengthens the drying. The filling rate of the material in the shell 200 is very high, which can reach 80%-90%. The residence time of the material can be adjusted from a few minutes to a few hours by adjusting parameters such as the feeding speed, the rotation speed of the stirring shaft 230, and the material filling degree. In addition, the movement of the material from the feed port 220 to the discharge port 260 in the shell 200 is basically a piston motion, and the residence time distribution is narrow, so the moisture content of the product is uniform. The paddle 240 has a certain axial angle on the stirring shaft 230, so the material can be dried continuously.

Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
