Abstract
Description
Technical Field
[0001] This utility model relates to the field of black tea processing technology, specifically to a drying device for black tea processing. Background Technology
[0002] Black tea, a fully fermented tea, is the second largest tea category in China. It gets its name from the red color of its brewed tea liquor and leaves. It is made from the buds and leaves of the tea plant, refined through typical processes such as withering, rolling, fermentation, and drying. During fermentation, the chemical reactions of tea polyphenols in black tea are reduced by more than 90%, and new components such as theaflavins and thearubigins are produced. Black tea processing requires two drying processes. First, it is thinly spread and dried until the moisture content is reduced by 80%. After a second fermentation, it is then thickly spread and dried until completely dry.
[0003] Currently, in the drying process of black tea, the tea is mostly spread manually in the drying frame, and the thickness depends on the worker's experience. This method of spreading tea leaves makes it impossible to determine the thickness, and the efficiency of spreading tea leaves is also low, which affects the processing and drying efficiency of black tea.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figures 1 to 7 The drying equipment shown includes:
[0028] Drying box 1, with a door 23 hinged to the front end of drying box 1, multiple drying frames 2 inside drying box 1, an adjustment frame 3 at the top of drying frame 2, an adjustment groove 4 at the top of drying frame 2, the bottom of adjustment frame 3 extending into the adjustment groove 4, an adjustment component at the bottom of drying frame 2, the adjustment component being used to adjust the height of adjustment frame 3, and scale lines 5 being machined on adjustment frame 3.
[0029] The movable rod 6 has multiple scraping teeth 7 fixedly installed at its bottom end. A connecting block 8 is fixedly connected to both ends of the movable rod 6. The two connecting blocks 8 are respectively located on both sides of the adjustment frame 3. A limiting guide block 9 is fixedly installed on the inner side of one end of the connecting block 8. A limiting guide groove 10 is opened at the top of both sides of the adjustment frame 3. The limiting guide block 9 is located inside the limiting guide groove 10. A handle is fixedly installed on the movable rod 6.
[0030] The adjustment assembly includes two threaded rods 11 disposed inside the adjustment groove 4. The bottom end of the threaded rod 11 passes through the bottom end of the drying frame 2 and is rotatably connected to the bottom end of the drying frame 2. Two threaded grooves 12 are opened at the bottom end of the adjustment frame 3. The top end of the threaded rod 11 extends into the threaded groove 12 and is threadedly connected to the threaded groove 12. A throttle 13 is fixedly provided at the bottom end of one of the threaded rods 11. A synchronous pulley 14 is fixedly provided on the outer side of the bottom end of the threaded rod 11. The synchronous pulley 14 is disposed between the throttle 13 and the bottom end of the drying frame 2. The two synchronous pulleys 14 are connected by a synchronous belt 15.
[0031] The front end of the drying frame 2 is provided with a movable baffle 16. The bottom end of the movable baffle 16 passes through the drying frame 2 and extends to the bottom of the drying frame 2. The movable baffle 16 is provided with a limiting component, which includes a limiting rod 17 located at the front end of the drying frame 2. The front end of the movable baffle 16 is provided with multiple limiting grooves 18. One end of the limiting rod 17 passes through the front end of the drying frame 2 and extends into one of the limiting grooves 18. The other end of the limiting rod 17 is fixedly provided with a pull block 19. A spring 20 is sleeved on the outer end of the limiting rod 17. The two ends of the spring 20 are fixedly connected to the front end of the drying frame 2 and the rear end of the pull block 19, respectively.
[0032] A connecting support plate 21 is fixed on both sides of the drying frame 2. Multiple sets of limiting support plates 22 are fixed on both sides of the inner side wall of the drying box 1. Each set of limiting support plates 22 consists of two plates. The connecting support plate 21 is located between two of the limiting support plates 22.
[0033] Rotating the handle 13 causes one threaded rod 11 to rotate. This threaded rod 11, through two synchronous pulleys 14 and a synchronous belt 15, drives another threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the threaded groove 12, the adjusting frame 3 moves up and down with the rotation of the threaded rod 11, thus adjusting the height of the adjusting frame 3. During the adjustment process, observe the scale line 5 to directly determine the internal depth of the adjusting frame 3 and the drying frame 2. The required internal depth of the adjusting frame 3 and the drying frame 2 can be obtained by adding the required thickness of the tea leaves to the height of the scraping teeth 7. Pulling the pull block 19 outward causes the limit rod 17 to move outward. The spring 20 is stretched by moving to the side. When one end of the limiting rod 17 leaves the inside of a limiting groove 18, the height of the movable baffle 16 above the drying frame 2 is adjusted so that the height of the movable baffle 16 on the drying frame 2 is consistent with the thickness of the tea to be spread. The fermented tea is placed inside the drying frame 2, and the handle is held to push the movable rod 6 forward. The movable rod 6 drives multiple scraping teeth 7 to scrape the tea. At this time, the multiple scraping teeth 7 will flatten the tea, and the excess tea will be moved to the front end by the scraping teeth 7 and then fall from the top of the movable baffle 16. In this way, the tea can be quickly spread flat inside the drying frame 2 and the adjusting frame 3, and the thickness is consistent.
[0034] This invention uses a drying frame 2 and an adjustment frame 3 with adjustable overall depth to place tea leaves. The thickness of the tea leaves can be adjusted according to the required drying thickness. The position of the movable baffle 16 can also be adjusted. Then, the movable rod 6 and multiple scraping teeth 7 are used to spread the tea leaves evenly, making the thickness of the tea leaves more accurate and uniform, and the efficiency of spreading the tea leaves is also higher, resulting in higher drying efficiency for black tea. This embodiment specifically solves the problem in the prior art that when black tea is spread in the drying frame, it is mostly spread manually, and the thickness of the spread depends on the worker's experience. This method of spreading tea leaves makes it impossible to determine the thickness and has low efficiency, which affects the drying efficiency of black tea processing.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
