Circular mesh plates 24 are symmetrically welded to the inner cavities of both the drying cylinder 8 and the dehumidifying cylinder 5. A mounting bearing 23 is welded and fixed to the center of the circular mesh plate 24, and a first stirring shaft 7 and a second stirring shaft 14 are respectively installed inside the mounting bearing 23. A servo motor 22 is bolted to the center of the side wall of the drying cylinder 8, and the output end of the servo motor 22 is keyed to one end of the first stirring shaft 7. A first pulley 15 is fixedly installed to one end of the first stirring shaft 7, and a second pulley 16 is fixedly installed to one end of the second stirring shaft 14. A drive belt 17 is sleeved between the first pulley 15 and the second pulley 16. On the other hand, a first circulating air pipe 19 is connected to one side of the inner cavity of the drying cylinder 8 and the dehumidifying cylinder 5, and a second circulating air pipe 25 is connected to the other side of the inner cavity of the drying cylinder 8 and the dehumidifying cylinder 5. A mounting base 20 is bolted to the fixed base 1, and an electric hot air blower 21 is bolted to the mounting base 20. The electric hot air blower 21 is connected to the first circulating air pipe 19. In use, the worker adds an appropriate amount of tea material to be dried into the inner cavity of the drying cylinder 8 through the first feed hopper 9, and an appropriate amount of molecular sieve into the inner cavity of the dehumidifying cylinder 5 through the second feed hopper 12. Then, the electric hot air blower 21 is started through the control panel 18, allowing the drying hot air to pass through the first circulating air pipe. Pipe 19 enters the inner cavity of the drying cylinder 8. At this time, the servo motor 22 drives the first stirring shaft 7 to rotate. Several turning shovels 13 are welded and installed on both the first stirring shaft 7 and the second stirring shaft 14, which can turn and shovel the tea material, so that the tea material and the drying hot air can come into contact more quickly and evenly, improving the drying efficiency and uniformity of the tea material. The dried hot air enters the inner cavity of the dehumidification cylinder 5 through the second circulating air pipe 25. Molecular sieves are used to absorb and remove water vapor from the drying hot air. Then the dried hot air enters the first circulating air pipe 19, and after being reheated by the electric hot air blower 21, it is circulated for reuse. This achieves dehumidification and drying of the dried hot air, and further recycles the drying hot air, greatly reducing the waste of exhaust heat and making it more practical. In addition, this utility model is provided with a discharge bottom plate 6 and a receiving box 2.

A second connecting seat 30 is rotatably connected to the second hinge seat 29. The second connecting seat 30 is welded to one side of the discharge bottom plate 6.Two receiving boxes 2 are symmetrically placed on the top surface of the fixed base plate 1. After the tea material is dried, the servo motor 22 stops working, and the first stirring shaft 7 and the second stirring shaft 14 no longer rotate. At this time, the tea in the drying cylinder 8 and the molecular sieve in the dehumidifying cylinder 5 fall into the two discharge base plates 6 respectively. Then, the first electric push rod 11 drives the lifting plate 4 to descend, separating the discharge base plate 6 from the drying cylinder 8 and the dehumidifying cylinder 5. Then, the second electric push rod 28 is activated through the control panel 18 to push the discharge base plate 6 to flip, so that the dried tea and the used molecular sieve can be poured into the inner cavities of the two receiving boxes 2 respectively, thus quickly completing the discharge of the dried tea material and making it more practical.
