Description

Technical Field

[0001] This utility model relates to the field of tea drying technology, and in particular to a drying device for tea processing. Background Technology

[0002] Drying is a crucial step in tea production. For some teas that require fermentation, such as black tea and oolong tea, drying promotes the reaction between enzymes and oxygen in the tea leaves. This causes oxidation and polymerization of substances like tea polyphenols, resulting in the tea's unique aroma and color.

[0003] However, some hot air drying ovens have simple internal structures, and the tea leaves are mostly stationary during the drying process. The tea leaves are piled together, with only the surface layer receiving adequate contact with the hot air, resulting in uneven heating of the inner leaves and low drying efficiency. Furthermore, stationary tea leaves are prone to localized overheating or overdrying, which not only affects the taste but may also damage the nutritional components of the tea. At the same time, these devices lack effective mechanisms for turning or shaking the tea leaves, failing to address the drying quality problems caused by uneven moisture distribution during the drying process. Therefore, a drying device for tea processing is proposed to solve these problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-2This utility model provides an embodiment of a drying device for tea processing, including a drying chamber 1. The rear end of the drying chamber 1 is equipped with corresponding electronic control components, which are existing technologies and will not be explained in detail here. A protective door 2 is rotatably connected to the left side of the interior of the drying chamber 1. The protective door 2 can be closed. A placement box 3 is provided inside the drying chamber 1 for placing tea leaves to be dried. A shaking mechanism 4 is provided on the inner wall of the drying chamber 1. The shaking mechanism 4 allows the tea leaves to move during drying, thereby improving drying efficiency.

[0034] Reference Figures 2-4 The shaking mechanism 4 includes a rotating column 402, which is T-shaped with a larger diameter on the side closer to the placement box 3 than on the side farther away. A positioning column 407 is fixedly connected to the side of the rotating column 402 closest to the placement box 3. The positioning column 407 is also T-shaped, which facilitates overall connection. A base 403 is rotatably connected to the inner wall of the drying oven 1. Connecting plates 406 are fixedly connected to the outer arc surfaces at both ends of the base 403. The movement trajectory of the connecting plates 406 is consistent with that of the base 403. A baffle 405 is fixedly connected to the inner top of the placement box 3. The baffle 405 allows the placement box to... When the box 3 is shaken, the baffle 405 prevents the tea leaves from moving out. Multiple sets of rotating columns 402 are provided, and the multiple sets of rotating columns 402 are connected by a belt 408. The belt 408 ensures that the movement trajectory of the multiple sets of rotating columns 402 is consistent. The outer wall of the baffle 405 is provided with a stabilizing component, which improves the stability of the multiple sets of placement boxes 3 when rotating. A motor 401 is fixedly connected to the right side of the drying box 1, and the motor 401 drives the shaking mechanism 4 to move. The inner side wall of the placement box 3 is provided with a take-out mechanism 5, which allows the dried tea leaves to be taken out quickly.

[0035] Reference Figures 2-4 The stabilizing components include a connecting plate 404. Two sets of placement boxes 3 are provided, and the two sets of placement boxes 3 are rotatably connected by the connecting plate 404. The setting of the connecting plate 404 makes the rotation of multiple sets of placement boxes 3 more stable. A through groove is opened on the outer wall of the connecting plate 406. The outer arc surface of the positioning column 407 contacts the inner wall of the through groove. The movement of the positioning column 407 on the inner wall of the through groove causes the connecting plate 406 to swing. The outer arc surface of the rotating column 402 is rotatably connected to the inner wall of the drying box 1. The rotation setting avoids movement interference. The bottom end of the placement box 3 is fixedly connected to the top end of the base 403. The swing of the base 403 drives the placement box 3 to swing. The output end of the motor 401 is fixedly connected to the right end of the upper rotating column 402. The rotation of the output end of the motor 401 drives the uppermost rotating column 402 to rotate, thereby causing the belt 408 to move.

[0036] Reference Figures 4-6The removal mechanism 5 includes a movable frame 501. A fixing block 502 is fixedly connected to the front left side of the movable frame 501. A handle is provided at the front end of the movable frame 501 to facilitate removal of the movable frame 501. A positioning plate 503 is fixedly connected to the left end of the placement box 3. A friction plate 505 is rotatably connected to the right side of the positioning plate 503. A rubber ball is provided on the right side of the friction plate 505. A support block 506 is fixedly connected to the front side of the placement box 3. A limit post 507 is elastically connected to the inner wall of the support block 506 through a connecting spring 504. A slope is opened on the right side of the limit post 507, and the slope is set to face forward. The bottom hemispherical surface of the friction plate 505 contacts the left side of the limit post 507. A ball hole is opened on the left side of the limit post 507. The two contact each other to prevent the limit post 507 from moving. The right side of the limit post 507 is inserted into the inner wall of the fixing block 502. The insertion setting prevents the movable frame 501 from moving.

[0037] Reference Figures 4-6 The outer wall of the movable frame 501 is slidably connected to the inner side wall of the placement box 3. The bottom of the movable frame 501 is hollowed out. When the movable frame 501 moves forward, all the dried tea leaves can be removed, making it convenient to collect the dried tea leaves. One end of the connecting spring 504 is fixedly connected to the inner wall of the support block 506, and the other end of the connecting spring 504 is fixedly connected to the outer arc surface of the limiting post 507. The outer wall of the limiting post 507 is slidably connected to the inner wall of the support block 506. The elasticity of the connecting spring 504 enables the limiting post 507 to have the functions of reset and limiting.

[0038] Working Principle: The operator opens the protective door 2, which is rotatably connected to the left side of the drying chamber 1, and places the tea leaves to be dried into the placement box 3 inside the drying chamber 1. After placing the tea leaves, the protective door 2 is closed, and the motor 401, which is fixedly connected to the right side of the drying chamber 1, is started. The output end of the motor 401 drives the uppermost rotating column 402, which is fixedly connected to it, to rotate. Since multiple rotating columns 402 are connected by a belt 408, the rotation of the uppermost rotating column 402 will drive the belt 408 to move, thereby causing the other rotating columns 402 to rotate synchronously. As the rotating column 402 rotates, it moves along the inner wall of the through groove opened on the outer wall of the connecting plate 406. The movement of the positioning column 407 in the through groove causes the connecting plate 406 to swing. Since the connecting plate 406 is fixedly connected to the base 403 and their movement trajectories are consistent, the swing of the connecting plate 406 will cause the base 403 to swing as well. Because the bottom end of the placement box 3 is fixedly connected to the top end of the base 403, the swing of the base 403 drives the placement box 3 to swing. The two sets of placement boxes 3 are rotatably connected by a connecting plate 404. The connecting plate 404 improves the stability of the multiple sets of placement boxes 3 when rotating, allowing the tea leaves to move during the drying process, thereby improving the drying efficiency. The baffle 405 fixedly connected to the inner side of the top of the placement box 3 can prevent the tea leaves from moving out during subsequent shaking.

[0039] After the tea leaves are dried, open the protective door 2 and place the collection box in front of the drying chamber 1. The operator holds the handle at the front end of the moving frame 501 and rotates the friction plate 505 upwards, causing the rubber ball of the friction plate 505 to disengage from the left side of the limiting post 507. Then, move the limiting post 507 to the left, and the moving frame 501 can be pulled forward. When the moving frame 501 moves forward, all the dried tea leaves can be moved out of the placement box 3 and fall onto the inner wall of the collection box for easy collection. After collection, move the moving frame 501 backwards, so that the moving frame 501 and its fixing block 502 press against the limiting post 507. When the moving frame 501 is fully reset, the connecting spring 504 restores its elastic deformation, pushes the limiting post 507 to reset, and then inserts into the fixing block 502. Then, rotate the friction plate 505 downwards so that the rubber ball contacts the limiting post 507.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
