[0002] After being picked, tea leaves go through a series of processes, such as drying, withering, and rolling, which may damage the structure of the tea leaves and release the oxidized cell fluid in them. If they are not dried in time, the tea leaves will continue to ferment, affecting their quality and taste. Drying can evaporate the moisture in the tea leaves, quickly stop the basic fermentation, and maintain the moisture content and shape of the tea leaves.

[0003] Therefore, tea drying is a necessary procedure in tea processing and is very critical. Currently, tea drying generally takes various forms such as drying, frying and sun drying. When hot air drying is performed by hot air drying equipment, hot air is generally directly introduced into the drying chamber to dry the tea.

[0004] However, in the above-mentioned hot air drying equipment, the hot air flow entering the drying chamber cannot stay in the drying chamber for a long time, and will flow out quickly, and the contact with the tea leaves is insufficient, and the heat utilization efficiency is low; at the same time, it is difficult to heat the tea leaves evenly, and the tea leaves are poorly heated, resulting in low drying efficiency and poor effect. Utility Model Content

When in use, hot air enters the clamping cavity 5 between the heating plates 3 through the air inlet 7, and will be diverted by the first diversion structure 6. The evenly diverted hot air flow will enter each connecting hole 10 and enter the concave cavity 8 of the support frame 4. After being evenly diverted again by the second diversion structure 9, the hot air flow will flow from the bottom of the mesh plate 12 upward through the mesh holes to evenly heat and dry the spread tea leaves quickly, with high drying efficiency. At the same time, during drying, the hot air flow from bottom to top will loosen the tea leaves, which is conducive to full contact between the hot air flow and the tea leaves, further improving the drying efficiency and drying effect.

[0025] Specifically, the heating plate 3 divides the drying chamber 2 into two symmetrical chambers, and the support frames 4 are symmetrically arranged on both sides of the heating plate 3. In this embodiment, the airflow on both sides is balanced and even, and more support frames 4 can be arranged to fully utilize the space.

[0026] Specifically, the first diversion structure 6 includes a plurality of triangular diversion blocks 13, the triangular diversion blocks 13 are evenly spaced in multiple rows from top to bottom, the triangular diversion blocks 13 in adjacent rows are staggered, and the connecting holes 10 are evenly distributed between the triangular diversion blocks 13; in the present embodiment, the hot air enters the sandwich cavity 5 between the heating plates 3 through the air inlet 7, and will be blocked by the plurality of triangular diversion blocks 13. Since the triangular diversion blocks 13 are evenly spaced in multiple rows from top to bottom, the triangular diversion blocks 13 in adjacent rows are staggered, the hot air flow will be diverted, and the connecting holes 10 are evenly distributed between the triangular diversion blocks 13, then the hot air flow after even diversion will enter each connecting hole 10 and enter the concave cavity 8 of the support frame 4.

[0027] Specifically, the second diversion structure 9 includes a plurality of triangular convex columns 14, and the triangular convex columns 14 are arranged in multiple rows from one side close to the heating plate 3 to the other side, and the triangular convex columns 14 in adjacent rows are staggered, and the connecting holes 10 corresponding to the support frame 4 are evenly spaced.

After being evenly diverted again, the hot air flow is evenly heated and dried on the spread tea leaves from the bottom of the mesh plate 12 upward through the mesh holes, and the drying efficiency is high.

[0030] Specifically, the air outlet 11 is equipped with a filter 17; in this embodiment, the hot air flow may carry tea leaves, which are filtered to prevent them from being directly discharged into the air and affecting the external working environment.

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] Working principle: when in use, hot air enters the sandwich cavity 5 between the heating plates 3 through the air inlet 7, and will be blocked by multiple triangular diverter blocks 13. Since the triangular diverter blocks 13 are evenly spaced in multiple rows from top to bottom, the triangular diverter blocks 13 in adjacent rows are staggered, the hot air flow will be diverted, and the connecting holes 10 are evenly distributed between the triangular diverter blocks 13. Then, the hot air flow after uniform diversion will enter each connecting hole 10 and enter the concave cavity 8 of the support frame 4. Since the triangular convex columns 14 are arranged in multiple rows from one side close to the heating plate 3 to the other side, the triangular convex columns 14 in adjacent rows are staggered, and the hot air flow will be blocked and diverted by three convex columns 14 after entering the concave cavity 8. After being evenly diverted again, the hot air flow is evenly heated and dried from the bottom of the mesh plate 12 upward through the mesh holes, and the drying efficiency is high. At the same time, during drying, the hot air flow from bottom to top will loosen the tea leaves, which is conducive to full contact between the hot air flow and the tea leaves, further improving the drying efficiency and drying effect.
