Description

Technical Field

[0001] This application relates to the field of tea processing technology, specifically to a tea withering device. Background Technology

[0002] Withering is a key step in tea processing, aiming to improve tea quality through appropriate moisture evaporation and transformation of internal chemical components.

[0003] Traditional withering methods mostly involve natural spreading or simple rack withering, which suffer from low efficiency, high susceptibility to environmental conditions, and uneven turning, easily leading to inconsistent withering degrees and affecting the overall quality of the finished tea. Although some existing withering equipment has certain mechanical turning functions, it still suffers from problems such as complex structure, incomplete turning, tea accumulation, and imprecise temperature and humidity control, making it difficult to achieve efficient and uniform withering.

[0004] Therefore, there is an urgent need for a withering device that can achieve uniform spreading of tea leaves, automatic turning, and controllable temperature and humidity, in order to improve withering efficiency and tea quality. Utility Model Content

[0005] Therefore, this application provides a tea leaf withering device to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A tea leaf withering device, comprising:

[0008] A fermentation cylinder, wherein a cover is bolted to the front opening of the fermentation cylinder;

[0009] The inner wall of the fermentation tank is equipped with a heating mechanism to heat the environment inside the fermentation tank;

[0010] A first mounting box is installed at the rear end of the fermentation tank. A drive wheel is provided inside the first mounting box. A second mounting box is installed at the rear end of the first mounting box. A servo motor is installed inside the second mounting box. The output end of the servo motor is connected to the drive wheel.

[0011] A loading mechanism is installed inside the fermentation tank, and a connecting wheel is installed at the rear end of the loading mechanism. The connecting wheel is movably connected to the fermentation tank, and the connecting wheel is meshed with the drive wheel.

[0012] A vibration mechanism is also installed at the rear end of the connecting wheel, which drives the connecting wheel to move back and forth.

[0013] Optionally, a thermometer and hygrometer are also installed on the front side of the cap to monitor the temperature and humidity inside the fermentation tank.

[0014] Optionally, the loading mechanism includes a wilting trough, a first mesh plate is installed on the lower side of the wilting trough, and a second mesh plate is installed on the side of the wilting trough away from the first mesh plate by bolts.

[0015] Optionally, partition strips are installed on both the upper and lower sides of the withering trough.

[0016] Optionally, the spacing between the dividing strips on the upper and lower sides of the withering trough is not equal.

[0017] Optionally, the vibration mechanism includes a connecting rod, which is installed at the rear end of the connecting wheel. The fermentation cylinder has a hole-like structure on its inner side for the connecting wheel to move. A water droplet wheel is fitted to the rear side of the connecting rod. The water droplet wheel is connected to the output end of a second drive motor installed on the outside of the second mounting box. The connecting rod is elastically connected to the first mounting box through a spring.

[0018] Optionally, the connecting rod and the connecting wheel are rotatably connected.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. This device, by setting up a rotatable loading mechanism and its meshing connection with the drive wheel and connecting wheel, enables the tea leaves to be automatically turned at a fixed angle, avoiding one side from always contacting the withering trough, and significantly improving the uniformity of withering.

[0021] 2. The vibration mechanism, through the cooperation of the water droplet wheel and the connecting rod, drives the loading mechanism to move back and forth, so that the tea leaves are continuously spread out during the withering process, preventing accumulation and further ensuring the consistency of withering.

[0022] 3. The withering trough is equipped with partitions at unequal intervals on the upper and lower sides. During the rotation, the tea leaves are moderately agitated, which enhances ventilation and moisture evaporation, thereby improving withering efficiency. Attached Figure Description

Detailed Implementation

[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This utility model provides a tea withering device, which includes a fermentation cylinder 1. A cover 2 is bolted to the front opening of the fermentation cylinder 1. The cover 2 has a detachable structure and seals the inside of the fermentation cylinder 1 to prevent the internal environment of the fermentation cylinder 1 from contacting the external environment, thus ensuring a clean withering environment.

[0032] A heating mechanism 12 is installed on the inner wall of the fermentation tank 1 to heat the environment inside the fermentation tank 1 and provide a suitable withering environment;

[0033] A thermometer and hygrometer 13 is also installed on the front side of the cap 2 to monitor the temperature and humidity inside the fermentation tank 1;

[0034] A first mounting box 3 is installed at the rear end of the fermentation tank 1. A drive wheel 6 is provided inside the first mounting box 3. A second mounting box 4 is installed at the rear end of the first mounting box 3. A servo motor 5 is installed inside the second mounting box 4. The output end of the servo motor 5 is connected to the drive wheel 6, so that the servo motor 5 drives the drive wheel 6 to rotate.

[0035] A loading mechanism 9 is installed inside the fermentation cylinder 1. A connecting wheel 8 is installed at the rear end of the loading mechanism 9. The connecting wheel 8 is movably connected to the fermentation cylinder 1. The connecting wheel 8 is meshed with the drive wheel 6, so that the drive wheel 6 can drive the connecting wheel 8 to rotate, thereby driving the loading mechanism 9 to rotate. The fixed-angle rotation of the servo motor 5 is used to turn the tea leaves in the loading mechanism 9 180°, so as to avoid the one side of the withered tea leaves always being in contact with the inside of the loading mechanism 9, which would result in uneven withering.

[0036] The loading mechanism 9 includes a withering trough 901, a first mesh plate 902 is installed on the lower side of the withering trough 901, and a second mesh plate 903 is installed on the side of the withering trough 901 away from the first mesh plate 902 by bolts, so that both the first mesh plate 902 and the second mesh plate 903 can be breathable and facilitate the drainage of moisture.

[0037] Divider strips 904 are installed on both the upper and lower sides of the withering trough 901 to divide the plane inside the withering trough 901 into multiple troughs to prevent excessive accumulation of tea leaves.

[0038] The spacing of the dividing strips 904 on the upper and lower sides of the withering trough 901 is not equal, which allows the withering trough 901 to stir the tea leaves to a certain extent during rotation.

[0039] A vibration mechanism is also installed at the rear end of the connecting wheel 8. The vibration mechanism drives the connecting wheel 8 to move back and forth, so that the tea leaves in the loading mechanism 9 can be laid flat.

[0040] The vibration mechanism includes a connecting rod 10, which is installed at the rear end of the connecting wheel 8. The inner side of the fermentation cylinder 1 is provided with a hole-like structure for the connecting wheel 8 to move, so that the connecting wheel 8 can slide and rotate within the hole-like structure. A water droplet wheel 7 is attached to the rear side of the connecting rod 10. The water droplet wheel 7 is connected to the output end of the second drive motor 11 installed on the outside of the second mounting box 4. The connecting rod 10 is elastically connected to the first mounting box 3 through a spring, so that after the second drive motor 11 drives the water droplet wheel 7 to rotate, the water droplet-shaped cross section of the water droplet wheel 7 drives the connecting rod 10 to move back and forth, thereby driving the connecting wheel 8 to move back and forth.

[0041] The connecting rod 10 and the connecting wheel 8 are rotatably connected to prevent the rotation of the connecting wheel 8 from synchronously driving the connecting wheel 8 to rotate, thereby preventing the spring from being excessively twisted and unable to return to its original position.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
