[0002] Tea withering is an important step in the tea-making process. It refers to the gradual loss of moisture from newly picked tea leaves under specific environmental conditions, and a series of physical and chemical changes that produce a specific aroma and taste. This process involves spreading the tea leaves evenly and drying them in the sun to wilt them, thereby promoting the activity of enzymes inside the tea leaves, causing moderate physical and chemical changes in the substances contained, dissipating some of the moisture, causing the stems and leaves to wilt, become dark green in color, and lose their grassy smell. The main purpose of withering is to dissipate the moisture of the tea leaves, reduce the enzyme activity in the fresh leaves, thereby stopping the enzymatic oxidation of tea polyphenols in the fresh leaves and keeping the fresh leaves green. In addition, withering also helps to remove the favor of the tea leaves, allowing the aroma and taste of the tea leaves to be formed.

[0024] Reference Figure 1-3A tea drying and withering rack capable of automatically turning over tea leaves comprises a base 1, a movable wheel 2 is arranged at the bottom of the base 1, a bottom plate 3 is arranged on the surface of the base 1, a vertical rod 5 is fixedly installed on the top of the bottom plate 3 near the side wall, a drying frame 6 is evenly fixedly installed on the surface of the vertical rod 5, a drying plate 11 is arranged inside the drying frame 6, a connecting rod 10 is slidably connected inside the vertical rod 5, a turning frame 9 is slidably connected on the surface of the connecting rod 10, a second cylinder 15 is fixedly installed on the surface of the connecting rod 10, an output port of the second cylinder 15 is fixedly connected to the turning frame 9, and a vertical rod 10 is fixedly installed on the surface of the connecting rod 10. The vibration mechanism assists in turning over the tea leaves. When in use, pour the tea leaves onto the drying board 11, and place the drying board 11 into the drying frame 6 in turn. Use the moving wheel 2 to move the whole to a suitable position. When turning over is required, start the second cylinder 15. The second cylinder 15 drives the turning frame 9 to move back and forth, thereby moving the tea leaves in the drying board 11, which helps to turn over the tea leaves. No manual turning is required, saving manpower. At the same time, with the cooperation of the vibration mechanism, the turning over of the tea leaves can be further strengthened, making the turning of the tea leaves more complete, further improving the withering effect, and facilitating practical use.
[0025] Furthermore, the vibration mechanism includes a motor 13, a groove is provided on the surface of the base 1, an eccentric wheel 12 is rotatably connected inside the groove, the motor 13 is fixedly installed on the side wall of the groove, the output port of the motor 13 is fixedly connected to the eccentric wheel 12, a limiting rod 4 is fixedly installed on the surface of the base 1, and the limiting rod 4 slides through the bottom plate 3. When the vibration mechanism is in use, the motor 13 is started, the motor 13 drives the eccentric wheel 12 to rotate, and the eccentric wheel 12 drives the bottom plate 3 to reciprocate on the surface of the limiting rod 4 in the up and down directions. The bottom plate 3 drives the vertical pole 5, the drying frame 6 and the drying board 11 to vibrate synchronously, so that the tea leaves are turned over in the drying frame 6, and no manual turning is required, so that the tea leaves are withered more evenly, thereby improving the withering effect.
[0026] Furthermore, the turning frame 9 includes a vertical rod 91, a first long rod 92 is evenly fixedly installed on the side wall of the vertical rod 91, the first long rod 92 slides through the connecting rod 10, a second long rod 93 is fixedly installed on the end of the first long rod 92, and a lever 94 is evenly fixedly installed on the bottom of the second long rod 93. The turning frame 9 is composed of the vertical rod 91, the first long rod 92, the second long rod 93, and the lever 94 to facilitate the simultaneous turning of tea leaves on multiple drying boards 11.
[0027] Furthermore, a rectangular groove is provided on the surface of the vertical rod 5, and the connecting rod 10 is slidably connected inside the rectangular groove. A first cylinder 14 is fixedly installed on the bottom wall of the rectangular groove, and the output port of the first cylinder 14 is fixedly connected to the connecting rod 10. By setting the first cylinder 14, the first cylinder 14 can mobilize the connecting rod 10 to slide up and down, and then the connecting rod 10 drives the turning rack 9 to slide up and down. When the drying board 11 needs to be placed inside the drying frame 6, the first cylinder 14 can be used to drive the entire turning rack 9 to move up, so that the shifting block is away from the drying frame 6, thereby freeing up space for placing the drying board 11. When the drying board 11 is placed, the entire turning rack 9 can be moved down so that the shifting block is located on the surface of the drying board 11, which helps the shifting block to turn the tea leaves.
[0028] Furthermore, a sun visor 7 is provided on the top of the vertical pole 5, and a plug rod 8 is fixedly installed on the bottom of the sun visor 7. A slot that matches the size of the plug rod 8 is opened on the top of the vertical pole 5. By arranging the plug rod 8 and the sun visor 7, the tea leaves in the top drying board 11 that are excessively withered due to sun exposure can be prevented. The sun visor 7 can also have the function of blocking rainwater to avoid the phenomenon that the workers cannot collect all the tea leaves in time due to heavy rain. The sun visor 7 can be disassembled to enhance the flexibility of use.
[0029] Furthermore, the drying board 11 is configured as a frame-shaped structure, and the bottom of the drying board 11 is configured as a ventilation net. By configuring the ventilation net, the withering effect of the tea leaves is better.
[0030] In summary, when in use, pour the tea leaves onto the drying board 11, put the drying board 11 into the drying frame 6 in sequence, and use the moving wheels 2 to move the whole to a suitable position. When it is necessary to turn over the tea leaves, start the second cylinder 15, and the second cylinder 15 drives the turning frame 9 to move back and forth, so as to stir the tea leaves in the drying board 11, which is helpful to turn over the tea leaves. There is no need for manual turning, which saves manpower. At the same time, with the cooperation of the vibration mechanism, the turning over of the tea leaves can be further strengthened, so that the turning of the tea leaves is more complete, and the withering effect is further improved, which is convenient for practical use. When the vibration mechanism is in use, the motor 13 is started, and the motor 13 drives the eccentric wheel 12 to rotate, and the eccentric wheel 12 drives the bottom plate 3 to reciprocate and vibrate on the surface of the limiting rod 4 in the upper and lower directions. The bottom plate 3 drives the vertical rod 5, the drying frame 6 and the drying board 11 to vibrate synchronously, so that the tea leaves are turned over in the drying frame 6, and there is no need for manual turning, so that the tea leaves are withered more evenly, and the withering effect is improved. The turning frame 9 is composed of the vertical rod 91, The first long rod 92, the second long rod 93, and the shifting rod 94 together constitute a structure that facilitates the simultaneous flipping of the tea leaves on multiple drying boards 11. By setting the first cylinder 14, the first cylinder 14 can mobilize the connecting rod 10 to slide up and down, and then the connecting rod 10 drives the flipping rack 9 to slide up and down. When it is necessary to place the drying board 11 inside the drying frame 6, the first cylinder 14 can be used to drive the entire flipping rack 9 to move up, so that the shifting block is away from the drying frame 6, thereby freeing up space for placing the drying board 11. When the drying board 11 is placed, the entire flipping rack 9 can be moved down so that the shifting block is located on the surface of the drying board 11, which helps the shifting block to flip the tea leaves. By setting the insertion rod 8 and the sunshade 7, the excessive withering of the tea leaves in the uppermost drying board 11 caused by sun exposure can be avoided. The sunshade 7 can also have the function of shielding rainwater to avoid the phenomenon that the heavy rain is too fast and the workers cannot collect all the tea leaves in time. The sunshade 7 can be disassembled to enhance the flexibility of use. By setting a ventilation net, the withering effect of the tea leaves is better.
