At the same time, the hot air conveyed by the hot air inlet pipe 302 will be diverted under the action of the air collecting hopper 305, thus increasing the coverage range of the hot air. During the drying process, by holding the rotating wheel 201 and rotating it, the rotation of the rotating wheel 201 drives the connecting rod 203 to rotate. The rotation of the connecting rod 203 drives the connecting sleeve 205 to rotate. The rotation of the connecting sleeve 205 drives the turning rod 207 to rotate. And during the rotation of the turning rod 207, it drives the movable ring 208 to rotate. The rotation of the movable ring 208 drives the stirring paddle 210 to rotate, thereby turning the chitosan inside the casing 101. And during the rotation of the stirring paddle 210, it drives the movable ring 208 to rotate. The rotation of the movable ring 208 drives the stirring paddle 210 to rotate, thereby increasing the turning effect on the chitosan inside the casing 101. Finally, the dried chitosan will be discharged to the outside through the discharge port 105 after being filtered by the sieve plate 107.
