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.
[0019] Reference Figures 1-3 A drying device for tea processing includes a housing 1, a heating base 101 fixedly connected to the bottom of the housing 1, an air inlet at the bottom of the housing 1, and further includes:
[0020] A drying drum 2 is rotatably connected to the inner wall of the box 1. The surface of the drying drum 2 is provided with filter holes. A connecting frame 201 is fixedly connected to the side wall of the box 1. A servo motor 202 is fixedly connected to the side wall of the connecting frame 201. A rotating shaft 203 is fixedly connected to the output end of the servo motor 202, and the rotating shaft 203 extends into the inner cavity of the drying drum 2. Multiple sets of rotating plates 204 are fixedly connected to the side wall of the rotating shaft 203. A scraper 205 is fixedly connected to the end of the rotating plate 204, and the scraper 205 is in contact with the inner wall of the drying drum 2.
[0021] The scraper 205 has multiple sets of holes 206 on its side wall, and the top of the box 1 is fixedly connected to the air outlet pipe 207.
[0022] It should be noted that: when tea leaves are placed in the inner cavity of the drying drum 2, the servo motor 202 is driven. The servo motor 202 drives the rotating plate 204 and scraper 205 to rotate through the rotating shaft 203, which can fully stir and disperse the tea leaves, making it easier for the tea leaves to dry. The rotating drying drum 2 can prevent the tea leaves from sticking to the surface of the drying drum 2 for a long time, causing the tea leaves to stick to the inner wall of the drying drum 2. The air inlet at the bottom of the box 1 and the filter holes on the surface of the drying drum 2 can fully mix the hot air emitted by the heating base 101 in the box 1 and the inner cavity of the drying drum 2. The filter holes on the surface of the drying drum 2 can also filter the debris in the tea leaves to the bottom wall of the box 1. The air outlet 207 can discharge the water vapor generated during the drying of the tea leaves.
[0023] Reference Figures 1-3 A connecting plate 3 is fixedly connected to the top of the box 1, and a rotating column 301 is rotatably connected to the side wall of the connecting plate 3;
[0024] Both the rotating column 301 and the side wall of the rotating shaft 203 are fixedly connected to pulleys, and the pulleys are rotatably connected by a belt 302.
[0025] A toothed ring 303 is fixedly connected to the side wall of the drying drum 2, and a gear 304 is fixedly connected to the side wall of the rotating column 301, and the gear 304 and the toothed ring 303 are meshed.
[0026] It should be noted that the rotating shaft 203 drives the rotating column 301 to rotate in the same direction through the pulley and belt 302. Since the gear 304 on the side wall of the rotating column 301 and the toothed ring 303 on the side wall of the drying barrel 2 are meshed, the rotating column 301 can drive the drying barrel 2 to rotate in the opposite direction. That is, the rotating shaft 203 and the drying barrel 2 rotate in opposite directions, which makes it easier to stir the tea leaves so that they can be spread out and fully dried.
[0027] Reference Figures 1-3 A sealing plug 4 is snapped into the side wall of the box 1. The sealing plug 4 is used to seal the box 1 and the drying drum 2.
[0028] It should be noted that by pulling out the sealing plug 4, the tea leaves can be placed inside the drying barrel 2. After drying, the dried tea leaves and the sifted tea leaves can be removed.
[0029] Operation method: Place the tea leaves in the inner cavity of the drying barrel 2, drive the servo motor 202, the servo motor 202 rotates through the rotating shaft 203, the rotating shaft 203 drives the rotating column 301 to rotate in the same direction through the pulley and belt 302. Since the gear 304 on the side wall of the rotating column 301 is meshed with the toothed ring 303 on the side wall of the drying barrel 2, the rotating column 301 can drive the drying barrel 2 to rotate in the opposite direction.
[0030] The rotating shaft 203 drives the rotating plate 204 and scraper 205 to rotate, which, combined with the counter-rotating drying barrel 2, can fully stir and disperse the tea leaves, making it easier to dry. At the same time, the rotating drying barrel 2 can prevent the tea leaves from sticking to the surface of the drying barrel 2 for a long time, causing the tea leaves to stick to the inner wall of the drying barrel 2. The air inlet at the bottom of the box 1 and the filter holes on the surface of the drying barrel 2 can fully mix the hot air emitted by the heating base 101 in the box 1 and the inner cavity of the drying barrel 2. The filter holes on the surface of the drying barrel 2 can also filter the tea leaves into the inner bottom wall of the box 1. The air outlet pipe 207 can discharge the water vapor generated during the drying of the tea leaves.
