[0035] In this embodiment, the baking tray 4 is placed inside the bracket 2, with one side engaging with the fixed arc plate 81. Then, the rotating block 87 is rotated, which in turn rotates the fixing screw 83. The rotation of the fixing screw 83 causes the drive plate 84, which is rotatably connected at one end, to move. The movement of the drive plate 84 causes the slide bar 85 to move, which in turn causes the moving arc plate 86 to move, thus clamping and fixing the baking tray 4. This allows the device to easily clamp and fix the baking tray 4 during use, improving its ease of use.

[0036] In this utility model, the cooling fan 73 is a previously disclosed technology, and the selected model is GX150-3.

[0037] The structure and operating principle of the drying device body 1, bracket 2, motor 3, drying tray 4, hot air blower assembly 5, and dust cover 6 in this utility model have been disclosed in a multi-stage hot circulation drying device for black tea disclosed in Chinese patent application number 201720718468.3. Its working principle is as follows: tea leaves are placed in the drying tray 4, the drying tray 4 is placed on the bracket 2, the door is closed, and the external power supply of the motor 3 and the hot air blower is connected. The motor 3 and the hot air blower start to work. The motor 3 drives the main shaft to rotate, the main shaft drives the connecting frame to rotate, the connecting frame drives the frame to rotate, and the frame drives the drying tray 4 to rotate so that the tea leaves inside the drying tray 4 are heated evenly. The hot air blower blows hot air into the interior of the chamber, so that the tea leaves inside the chamber are dried quickly.

[0038] The working principle and usage process of this utility model: This utility model is used for drying black tea. In use, tea leaves are placed on a drying tray 4, which is then placed on a support 2. The tray 4 is clamped and fixed by a fixing component 8. The door is then closed, and the external power supply to the motor 3 and the hot air blower assembly 5 is connected. The motor 3 and the hot air blower begin to work. The motor 3 drives the main shaft to rotate, which in turn drives the main shaft support 2. The support 2 then drives the drying tray 4 to rotate, ensuring even heating of the tea leaves inside the tray 4. The hot air blower blows hot air into the interior of the chamber, rapidly drying the tea leaves. During use, a dust cover 6 protects the motor 3 and the hot air blower assembly 5. A heat dissipation component 7 facilitates ventilation and heat dissipation inside the dust cover 6. When using the heat dissipation component 7, the cooling fan 73 is activated, and air enters through the holes in the cover plate 77, is filtered by the filter cartridge 76, and then enters the interior of the dust cover 6 through the ventilation duct seat 72 for heat dissipation. Finally, air exits from one side of the dust cover 6. The filter cartridge 76 can be removed from the support base 75 by unscrewing the fixing screw 782 and then removing the cover plate 77 through the handle 783 for cleaning or replacement. The bearing cover 71 can then be removed by unscrewing the mounting screw 785, facilitating cleaning and maintenance of the motor 3 and hot air blower assembly 5 inside the dust cover 6. This improves the ventilation and heat dissipation of the dust cover 6 during use, enhancing its practicality. When using the fixing assembly 8, the drying tray 4 is placed in the bracket 2, with one side engaging with the fixing arc plate 81. Rotating the rotating block 87 causes the fixing screw 83 to rotate, which in turn moves the drive plate 84 connected to one end. The drive plate 84 then moves the sliding rod 85, which in turn moves the moving arc plate 86, clamping and fixing the drying tray 4. This improves the ease of use of the device.
