[0020] This application provides a composite device for withering and fermenting white tea, effectively solving the technical problem that existing white tea withering and drying equipment often has a fixed angle. When the angle or height of the sun changes, the fixed angle drying may lead to uneven drying of white tea, or insufficient sunlight, resulting in delayed fermentation or mold growth, thus affecting the quality and efficiency of white tea withering. This device is equipped with a drying plate 3 that can be rotated and its angle adjusted. During the withering of white tea, the angle of the drying plate 3 can be adjusted by rotating it, so that it dynamically adapts to the sun's drying angle, allowing the tea leaves to receive sunlight evenly and avoiding localized over-withering or under-withering.
[0021] Example
[0022] The technical solution in this application embodiment is to effectively solve the technical problem that in the existing white tea withering and drying process, the angle of the drying equipment is mostly fixed. When the angle or height of the sun changes, the fixed angle drying may lead to uneven drying of white tea, or insufficient light exposure may lead to delayed fermentation or mold, affecting the quality and efficiency of white tea withering. The overall idea is as follows: A composite device for white tea withering and fermentation includes a fixed base 1. The fixed base 1 is provided with an adjustment mechanism to facilitate the withering of white tea. The adjustment mechanism includes a C-shaped frame 2, a drying plate 3 and a disc 4. The C-shaped frame 2 is located at the upper end of the fixed base 1. The drying plate 3 is rotatably installed on the C-shaped frame 2, which can evenly spread the tea leaves on the drying plate 3.
[0023] A rotating shaft 31 is fixedly installed on both sides of the drying board 3. The disc 4 is located on the side of the rotating shaft 31. A rotating shaft 23 is fixedly installed on the lower end of the C-shaped frame 2. The rotating shaft 23 is rotatably installed on the fixed base 1. A damping ring 11 is fixedly installed on the upper end of the fixed base 1. The damping ring 11 is located at the circumferential end of the rotating shaft 23. After the tea leaves are laid flat, the user can rotate the C-shaped frame 2 according to the position of the sun to drive the rotating shaft 23 to rotate. The rotating shaft 23 rotates on the fixed base 1. The damping ring 11 will provide a certain friction force when the rotating shaft 23 rotates.
[0024] Both ends of the C-shaped frame 2 are provided with mounting grooves 21. At least two limiting grooves 22 are also provided on the side ends of the C-shaped frame 2. A pull plate 32 is fixedly installed on the side end of the rotating shaft 31. A slot 33 is provided on the side end of the pull plate 32. The user can rotate the pull plate 32 to drive the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the drying board 3 to rotate. After the drying board 3 is adjusted to a suitable angle, the user can re-insert the limiting rod 42 into the corresponding limiting groove 22 to limit the drying board 3, and then continue the withering process of the white tea.
[0025] A limiting rod 42 is fixedly installed on the side end of the disc 4. The limiting rod 42 is installed through the inner wall of the slot 33. The end of the limiting rod 42 is located in the limiting groove 22. Two springs 41 are fixedly installed between the disc 4 and the pull plate 32. The user can adjust the angle of the drying plate 3 so that the white tea in the drying plate 3 can wither better. The user can pull the disc 4 to move the limiting rod 42. When the limiting rod 42 moves, it will leave the inner wall of the limiting groove 22, and the spring 41 will be stretched.
[0026] To address the problems existing in the prior art, this utility model provides a composite device for withering and fermenting white tea. This device is equipped with a drying plate 3 that can be rotated and its angle adjusted. When the white tea is withering, the angle of the drying plate 3 can be adjusted by rotating it, so that it can dynamically adapt to the angle of sun drying, so that the tea leaves can be evenly exposed to sunlight and avoid local over-withering or under-withering.
[0027] Fixed base 1: As the basic support structure of the equipment, it supports components such as C-shaped frame 2 and drying board 3, providing a stable working platform for the withering process of white tea.
[0028] Damping ring 11: Located at the circumferential end of the rotating shaft 23, it provides friction when the rotating shaft 23 rotates, preventing the C-shaped frame 2 and the drying board 3 from rotating accidentally due to accidental contact, and at the same time making the adjustment process more precise and controllable.
[0029] C-shaped frame 2: It is installed on the fixed base 1 via a rotating shaft 23 and can rotate around the rotating shaft 23. It is used to support the drying board 3 and drive it to adjust its direction according to the position of the sun, so as to achieve all-round sunlight exposure for white tea.
[0030] Installation groove 21: It is opened at both ends of the C-shaped frame 2 and is used to install the rotating shaft 31 of the drying board 3, so that the drying board 3 can rotate on the C-shaped frame 2 to achieve angle adjustment.
[0031] Limiting groove 22: The groove is arranged on the side end of the C-shaped frame 2 and cooperates with the limiting rod 42 to fix the angle of the drying board 3 and ensure that the drying board 3 remains stable during the withering process of white tea.
[0032] Rotating shaft 23: It is fixedly installed at the lower end of the C-shaped frame 2 and rotatably installed on the fixed base 1. It serves as the axis of rotation of the C-shaped frame 2, so that the C-shaped frame 2 can adjust its direction according to the position of the sun.
[0033] Drying board 3: It is rotatably mounted on the C-shaped frame 2 via the pivot 31. It is used to lay white tea leaves flat. The angle can be adjusted by rotating it so that the tea leaves can be evenly exposed to sunlight, thus promoting the withering process.
[0034] Rotating shaft 31: It is fixedly installed on both ends of the drying board 3 and rotatably installed in the mounting groove 21 of the C-shaped frame 2. It serves as the axis of rotation of the drying board 3 to realize the angle adjustment of the drying board 3.
[0035] Pull plate 32: Fixedly installed on the side end of the rotating shaft 31, used for manually rotating the drying board 3. By pulling the pull plate 32, the rotating shaft 31 can be rotated, thereby adjusting the angle of the drying board 3.
[0036] Slot 33: Through the side end of the pull plate 32, it is used to install the limiting rod 42, so that the limiting rod 42 can slide in the slot 33 to lock and unlock the angle of the drying board 3.
[0037] Disc 4: Located at the side end of the rotating shaft 31, it is connected to the pull plate 32 by a spring 41 and is used to control the movement of the limit rod 42. By pulling the disc 4, the limit rod 42 can be disengaged from the limit groove 22, thus releasing the lock on the drying board 3.
[0038] Spring 41: Connects the disc 4 and the pull plate 32. After the disc 4 is pulled, it provides a restoring force so that the limit rod 42 can automatically insert into the limit groove 22 when the disc 4 is released, thereby achieving rapid locking of the angle of the drying board 3.
[0039] Limiting rod 42: Fixedly installed on the side end of disc 4, passing through slot 33 and inserted into limiting groove 22, used to fix the angle of drying board 3 and ensure that drying board 3 remains stable during the withering process of white tea.
[0040] Working principle:
[0041] In the processing of white tea, withering can effectively enhance the aroma. Outdoor withering and fermentation are typically carried out by placing the white tea under the sun. When withering the white tea, the user can evenly spread the tea leaves on the drying board 3. After spreading the tea leaves, the user can rotate the C-shaped frame 2 according to the sun's position, causing the rotating shaft 23 to rotate. The rotating shaft 23 rotates on the fixed base 1. The damping ring 11 provides a certain friction force when the rotating shaft 23 rotates, preventing accidental rotation caused by contact with the C-shaped frame 2 or the drying board 3, and allowing for more accurate adjustment. The angle of the sun varies at different times of day, and the user can adjust the angle of the drying board 3 to ensure better withering of the white tea within it. The user can pull the disc 4 to move the limiting rod 42. The moving limiting rod 42 will move away from the inner wall of the limiting groove 22, stretching the spring 41. At this time, the user can rotate the pull plate 32 to rotate the rotating shaft 31, which in turn rotates the drying board 3. After the drying plate 3 is adjusted to a suitable angle, the user can re-insert the limiting rod 42 into the corresponding limiting groove 22 to limit the drying plate 3, and then continue the withering process of white tea. In the existing white tea withering and drying, the angle of the drying equipment is mostly fixed. When the angle or height of the sun changes, the fixed angle of drying may lead to uneven drying of white tea, or insufficient light exposure, resulting in delayed fermentation or mold, affecting the quality and efficiency of white tea withering. This device is equipped with a drying plate 3 that can be rotated and its angle adjusted. When the white tea is withering, the angle of the drying plate 3 can be adjusted by adjusting its rotation, so that it dynamically adapts to the sun's drying angle, allowing the tea leaves to receive sunlight evenly and avoiding local over-withering or under-withering. In addition, this device, through the cooperation of the damping ring 11, the disc 4 and the limiting rod 42, can make the drying plate 3 stably limited after rotation and adjustment, ensuring the stability of the tea leaves during the withering process. It is convenient to adjust and quick to use.
[0042] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
