Description

Technical Field

[0001] The present application relates to the technical field of tea processing, and more specifically, to a tea withering device. Background Art

[0002] Withering is a very important technological step in the production and preparation of tea. The withering of fresh tea mainly aims to allow the moisture in the tea to naturally evaporate, make the tea softer, not easy to break during fixation, and disperse the grassy smell.

[0003] After retrieval, in the existing publicly disclosed technology, the application number is: CN202323405822.1, a tea withering device, which realizes the unfolding of the screen through the setting of iron rings, thus facilitating the dust prevention of the containing part and reducing the influence of dust on tea. Under the magnetic attraction between the magnetic ring and the iron ring, the screen can be stored, which is beneficial to the collection and storage of tea and improves the practicability of the equipment; through the threaded connection between the lead screw and the nut sleeve, the height and spacing of the bearing plate can be adjusted, thereby improving the practicability of the equipment.

[0004] However, the above patent still has certain disadvantages in use: multiple bearing plates are stacked on top of each other for use, which causes the tea below to be blocked by the upper bearing plate, resulting in the tea not being fully exposed to sunlight, reducing the tea withering effect. Moreover, when turning the tea during withering, manual operation is adopted and it can only be turned once at intervals. At the same time, the movement of the scraper can only flatten the tea and cannot turn the tea over, resulting in poor drying of the back of the tea, a long withering time, limited production efficiency, and an overall unsatisfactory use effect.

[0005] In order to solve the above problems, the present application provides a tea withering device. Utility Model Content

[0006] The tea withering device provided by the present application adopts the following technical solutions:

[0007] A tea withering device includes a base and lockable movable wheels. A support rod is welded at the middle position of the top of the base. Several groups of adjusting seats are rotatably connected to the surface of the support rod. A withering plate is welded at one end of the adjusting seat. A driving shaft is installed at the middle position inside the withering plate. One end of the driving shaft penetrates through one side of the withering plate and is connected to a motor, and the motor is fixed to the bottom of the withering plate through a bracket. Several groups of connecting plates are circumferentially installed on the surface of the driving shaft. A scraper is installed at the bottom of the connecting plate. Several groups of air supply holes are circumferentially formed on the inner surface of the withering plate.

[0008] Through the above technical solution, the air supply holes are provided to accelerate the flow rate of the internal and external gases by the blowing of the gas, so as to speed up the drying effect of the tea leaves. At the same time, the tea leaves can be turned over by blowing, so that different surfaces of the tea leaves can be exposed to sunlight, improving the drying uniformity and drying effect.

[0009] Further, a blower is installed at one side of the top of the base. One end of the blower is connected to the support rod through an air delivery pipe. Air outlet holes for gas flow are provided at the internal position of the support rod, the contact position between the support rod and the adjustment seat, the internal position of the adjustment seat, and the internal position of the drying tray. A number of threaded holes are symmetrically provided at both ends of the air outlet holes on the surface of the support rod.

[0010] Through the above technical solution, the setting of the air outlet holes facilitates the flow of the gas introduced by the blower.

[0011] Further, the adjustment seat is fixed to the support rod by a fastening bolt.

[0012] Through the above technical solution, the fastening screw is provided to fix the adjustment seat after adjustment, avoiding rotation during use, which may cause occlusion between the drying trays, and further preventing the tea leaves below from being fully exposed to sunlight for drying operations.

[0013] Further, a number of lockable mobile wheels are evenly installed around the bottom of the base.

[0014] Through the above technical solution, the setting of the lockable mobile wheels facilitates the movement of the device, and thus facilitates its use at different positions.

[0017] Further, a groove for the rotation of the adjustment seat is provided on the surface of the support rod.

[0018] Through the above technical solution, the setting of the groove facilitates the installation of the adjustment seat, and thus prevents the adjustment seat from detaching, ensuring the adjustment track.

[0019] Further, the scraper is made of silica gel material.

[0020] Through the above technical solution, the selection of the silica gel material is to reduce the pushing damage of the scraper to the tea leaves and ensure the integrity of the tea leaves.

[0021] In summary, the present application includes the following beneficial technical effects:

[0022] During the airing operation of the present application, the position between multiple drying trays can be adjusted by rotating the adjusting seat, avoiding occlusion between the drying trays, so as to ensure that sunlight can evenly irradiate the surfaces of the drying trays at different positions. As a result, the tea leaves on its surface can be fully aired. Then, during subsequent airing, the operation of the motor can drive the scraper to rotate continuously. Through the rotation of the scraper, the tea leaves can be spread out flat, and at the same time, the tea leaves can be turned over by friction, enabling different surfaces of the tea leaves to fully contact sunlight. Moreover, the gas ejected from the air supply holes can also assist in turning over the tea leaves, reducing the difficulty of turning over. Consequently, the uniformity of tea leaf airing can be improved, thereby enhancing the overall airing effect. It has the advantages of uniform airing, less occlusion during airing, and easy turning over of tea leaves. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment:

[0033] The embodiment of the present application discloses a tea leaf airing device. Please refer to Figures 1-4 , including a base 1 and lockable mobile wheels 16. A support rod 3 is welded at the middle position on the top of the base 1. Several groups of adjusting seats 4 are rotatably connected to the surface of the support rod 3. A drying tray 5 is welded at one end of the adjusting seat 4. A driving shaft 7 is installed at the middle position inside the drying tray 5. One end of the driving shaft 7 penetrates through one side of the drying tray 5 and is connected to a motor 8, and the motor 8 is fixed to the bottom position of the drying tray 5 through a bracket. Several groups of connecting plates 6 are installed around the surface of the driving shaft 7. A scraping plate 9 is installed at the bottom position of the connecting plate 6. Several groups of air supply holes 14 are formed around the inner surface of the drying tray 5. The air supply holes 14 are provided to accelerate the flow rate of internal and external gases by the blowing of the gas, so as to speed up the drying effect of the tea leaves. At the same time, the tea leaves can be turned over by the blowing, so that different surfaces of the tea leaves can be exposed to the sun, improving the drying uniformity and drying effect.

[0034] Please refer to Figure 1 , a blower 15 is installed at one side position on the top of the base 1. One end of the blower 15 is connected to the support rod 3 through an air delivery pipe 2. Air outlet holes 17 for gas flow are formed at the position inside the support rod 3, at the contact position between the support rod 3 and the adjusting seat 4, inside the adjusting seat 4, and inside the drying tray 5. A plurality of groups of threaded holes 18 are symmetrically formed on the surface of the support rod 3 at both ends of the air outlet hole 17. The air outlet holes 17 facilitate the flow of the gas introduced by the blower 15.

[0035] Please refer to Figure 1 andFigure 4 The adjusting seat 4 is fixed to the support rod 3 through the fastening bolt 11. The fastening screw rod is provided to fix the adjusting seat 4 after adjustment, so as to prevent rotation during use, which may cause occlusion between the drying trays 5, resulting in insufficient sunlight exposure for the tea leaves below for drying operation.

[0036] Please refer to Figure 1 A number of groups of lockable moving wheels 16 are evenly installed around the bottom of the base 1. The setting of the lockable moving wheels 16 facilitates the movement of the device, thus facilitating its use in different positions.

[0037] Please refer to Figure 1 and Figure 2 One side of the top of the drying tray 5 is rotatably connected to a shielding tray 12. Lower air exchange holes 10 and upper air exchange holes 13 are respectively formed on the surface of the drying tray 5 and the surface of the shielding tray 12. The shielding tray 12 is provided to shield the top of the drying tray 5 to prevent foreign objects (such as leaves, branches, etc.) from falling into the drying tray and contaminating the tea leaves.

[0038] Please refer to Figure 1 and Figure 3 A groove for the rotation of the adjusting seat 4 is formed on the surface of the support rod 3. The setting of the groove facilitates the installation of the adjusting seat 4, thus preventing the adjusting seat 4 from detaching and ensuring the adjustment track.

[0039] Please refer to Figure 1 The scraper 9 is made of silicone material. The choice of silicone material is to reduce the pushing damage of the scraper 9 to the tea leaves and ensure the integrity of the tea leaves.

[0040] The implementation principle of this embodiment is as follows: During use, the operator can rotate multiple adjusting seats 4 to ensure that there is no mutual occlusion between the adjusting seats 4, so as to ensure that sunlight can evenly irradiate the surfaces of different drying trays 5, thereby improving the overall drying effect. During drying, the operation of the motor 8 can drive the scraper 9 to rotate continuously. The rotation of the scraper 9 can push the tea leaves to flatten them, and the tea leaves can also be turned over by friction during rotation, so that different surfaces of the tea leaves can be dried, thereby improving the overall drying effect and drying uniformity. When the scraper 9 moves, the gas ejected from the side air supply holes 14 can also blow the tea leaves, making it easier to turn the tea leaves over. At the same time, a shielding tray 12 is provided at the top of the drying tray 5, so that the tea leaves can be prevented from being blown out, avoiding waste of tea leaves. The device as a whole has the advantages of uniform drying, less drying occlusion, and tea leaf turnover.

[0041] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
