A plurality of support seats 2 are fixedly arranged at the bottom end of the outer shell 1. A control panel 3 is fixedly arranged on one side of one of the support seats 2. An air inlet hood 4 is penetrated and arranged at the bottom end of the outer shell 1. A plurality of air inlet fans 5 are fixedly arranged at the middle position inside the air inlet hood 4. An electric heating grid plate 6 is fixedly arranged at the top end inside the air inlet hood 4. An exhaust hood 7 is penetrated and arranged at the top end of the outer shell 1. A plurality of exhaust fans 8 are fixedly arranged at the middle position inside the exhaust hood 7. A dust collection cloth bag 9 is arranged at the top end of the exhaust hood 7. A mesh cylinder 10 is rotatably arranged inside the outer shell 1. The mesh cylinder 10 is connected to the outer shell 1 through two rotation drive assemblies 11 and a plurality of auxiliary support assemblies 12;
[0023] During operation, the device can be continuously fed through a conveyor belt. Tea leaves enter the interior of the mesh cylinder 10. The rotation drive assembly 11 drives the mesh cylinder 10 to rotate. The mesh cylinder 10 drives the tea leaves to tumble and move. The intake fan 5 is started, and air is introduced through the air intake hood 4. The electric heating grid plate 6 operates to heat the incoming air. The hot air can pass through the mesh cylinder 10 and heat the mesh cylinder 10 and the tea leaves. The heat radiation of the electric heating grid plate 6 can also achieve efficient heating. The hot air flows from the bottom to the top, thereby driving the wet air to be directly discharged through the exhaust hood 7 during the drying process, reducing the contact time between the wet air and the tea leaves, and thus improving the drying efficiency. During the process of discharging the wet air, fine impurities such as dust and tea hairs in the tea leaves can be carried out together, and then collected through the dust collection cloth bag 9 to prevent fine impurities such as dust and tea hairs from spreading to the working area and affecting the staff.
[0024] An air filter plate 13 is provided at the bottom end inside the air intake hood 4, which can filter the incoming air. The electric heating grid plate 6 is of an arc-shaped structure and can match the arc surface of the mesh cylinder 10.
[0025] The dust collection cloth bag 9 is of a detachable structure and can be regularly disassembled, cleaned or replaced.
[0026] End covers 14 are provided at both ends of the outer housing 1. The end covers 14 are rotatably connected to the outer housing 1 through damping hinges 15. The bottom end of the end cover 14 is of a flat mouth structure. The two ends of the outer housing 1 can be partially blocked through the end covers 14, reducing the possibility of wet air discharging from both ends of the outer housing 1. The bottom end of the end cover 14 is of a flat mouth structure, which can facilitate feeding and discharging at both ends of the outer housing 1.
[0027] The auxiliary support assembly 12 is composed of a support frame 16 and a bearing 17. The support frame 16 is fixedly connected to the inner side wall of the outer housing 1. The bearing 17 is connected between the support frame 16 and the mesh cylinder 10. The mesh cylinder 10 can be supported through the support frame 16 and the bearing 17, improving the stability and mobility of the mesh cylinder 10.
[0028] Spiral guide vanes 18 are fixedly arranged on the inner side wall of the mesh cylinder 10, which can drive the tea leaves to continuously move during the rotation of the mesh cylinder 10.
[0029] The rotation drive assembly 11 is composed of a servo motor 19, a drive gear 20 and an external gear ring 21. The servo motor 19 is fixedly connected to the outer housing 1. The drive gear 20 is fixedly connected to the output shaft of the servo motor 19. The external gear ring 21 is fixedly connected to the outer surface of the mesh cylinder 10 and meshes with the drive gear 20. A through groove 22 matching the drive gear 20 is provided on the outer housing 1.
[0030] When the rotary drive assembly 11 is working, the servo motor 19 drives the drive gear 20 to rotate, the drive gear 20 drives the outer gear ring 21 to rotate, and the outer gear ring 21 drives the mesh cylinder 10 to rotate.

During the air inlet process, the flow of air can also drive the tea leaves to tumble, improving the drying uniformity. During the rotation of the mesh cylinder, the tea leaves can be continuously driven to tumble, further improving the drying uniformity and drying efficiency. During the air outlet process, impurities such as dust and tea hairs in the tea leaves can be collected, preventing the direct discharge of dust, tea hairs and other impurities to the external working area and having an adverse impact on the staff. By providing an air filter plate, the intake air can be filtered. By providing a detachable dust collection cloth bag structure, the dust collection cloth bag can be regularly disassembled, cleaned or replaced. By providing end covers, the discharge of humid air from both ends of the outer casing can be effectively avoided. By providing an auxiliary support assembly composed of a support frame and bearings, the stability of the mesh cylinder can be improved. By providing spiral guide vanes, the tea leaves can be continuously moved during the rotation of the mesh cylinder.
