[0026] Combination Figure 1-6 As shown, a tea fermentation device comprises:

[0027] The box body 1 is a cylindrical structure, with a top cover 11 on the top, a through hole at the center of the top cover 11, and the top cover 11 and the top of the box body 1 are movably assembled by a threaded structure, mainly to facilitate the staff to disassemble the structure, and a box door 12 is also provided on the front of the box body 1, and a transparent window 13 for observing the interior is provided on the box door 12;

[0028] The rotating seat 2 is arranged on the inner bottom surface of the box body 1 and is rotatably connected to the box body 1 through a bearing structure. A rotating shaft 21 is vertically arranged at the center of the top surface thereof. The top end of the rotating shaft 21 faces upward and is just inserted into the through hole on the top cover 11, so that the top end thereof is connected with the external water pump;

[0029] The trays 3 are provided in plurality and are arranged on the rotating shaft 21 at intervals in the upper and lower directions;

[0030] The spray assembly 4 is disposed on the tray 3, and part of it is located at the connection between the tray 3 and the rotating shaft 21, so that the spray assembly 4 and the rotating shaft 21 are connected to each other for water supply, and at the same time, it plays a certain supporting and fixing effect;

[0031] The heating assembly 5 is a heating tube disposed around the inner wall of the box body 1 .

[0032] Specifically; inside the box body 1, the rotating shaft 21 is a base support for driving all the trays 3 to rotate. Therefore, a driving motor 6 for driving the rotating seat 2 and the rotating shaft 21 to rotate should be provided at the bottom of the box body 1. The driving motor 6 is fixedly installed at the center of the top surface of the box body 1 through the motor seat, so that its output end is arranged vertically upward and fixedly connected to the center of the bottom surface of the rotating seat 2.

[0033] While the rotating shaft 21 is rotating, it also needs to be supplied with water. Therefore, a clamping and fixing structure that can be expanded or closed should be provided at the center of the top surface of the top cover 11. Its purpose is to cooperate with the rotating seat 2 at the bottom to provide auxiliary support for the rotating shaft 21. In addition, in this structure, the interior thereof adopts a bearing structure to contact the outer wall of the rotating shaft 21 to ensure that the rotating shaft 21 can rotate flexibly.

[0034] A ball bearing seat is also provided on the inner wall of the top end of the rotating shaft 21 . The water pipe on the water pump is vertically inserted into the ball bearing seat and sealed on both sides by a sealing gasket so that the rotating shaft 21 can be rotated without affecting its operation.

[0035] The tray 3 is configured as two concentrically arranged annular plates, and the two annular plates are connected and fixed by a cross-shaped supporting rib 31, and a metal mesh is arranged on the surface. The side wall of the central hole of the tray 3 is just in contact with the outer wall of the rotating shaft 21. In order to further improve the convenience of sliding up and down, a plurality of guide grooves can be vertically arranged on the outer wall of the rotating shaft 21. At the same time, guard plates are arranged on the edge of the outer wall and the edge of the inner ring of the tray 3. The guard plate located at the inner ring partially extends toward the center direction, so that it can be slidably inserted into the guide groove, so that the up and down sliding operation of the entire structure is more convenient.

[0036] The spray assembly 4 includes an atomizing nozzle 43, a branch pipe 42 and a joint 41, wherein the atomizing assembly is divided into two groups, one of which is arranged on the top surface of the guard plate at the outer edge of the tray 3, and its nozzle is arranged tilted toward the center of the tray 3, the purpose of which is to completely cover all the tea leaves on the surface of the tray 3 through multiple nozzles, to ensure the uniformity of the humidity of the tea leaves during the humidification process;

[0037] The other group is located on the bottom surface of the supporting rib 31 and arranged vertically downward. The nozzles should be arranged obliquely upward to atomize and humidify from the bottom upward to avoid excessive accumulation of tea leaves, which will cause the tea leaves at the bottom to be unable to absorb moisture, thereby further improving the uniformity of humidification.

[0038] In addition, in order to facilitate water supply to the atomizing nozzles 43, the interior of the tray 3 should be set to be hollow, and the branch pipe 42 is installed inside the tray 3, and each branch joint 41 is connected to each atomizing nozzle 43;

[0039] A pin hole is provided on the guard plate on the inner edge of the tray 3, and the joint 41 is movably installed inside the pin hole. An adjustment cap is provided at one end, and a limit block is provided at the other end. Both structures are used to prevent the joint 41 from falling out. The joint 41 is also provided with a socket on the side wall surface inside the tray 3, and one of the branch pipes on the branch pipeline 42 is connected to the interior of the joint 41 through the socket.

[0040] Combined with the above-mentioned structure of the spray assembly 4, in this embodiment, in order for the spray assembly 4 to have both a supporting effect and a water delivery function, a plurality of water outlets 22 may be correspondingly arranged on the outer wall of the rotating shaft 21. To ensure the tight connection and sealing effect between the water outlet 22 and the joint 41, the two should be assembled and combined using a threaded structure, and the joint 41 and the water outlet 22 are both arranged in at least 3 groups. The staff only needs to twist the adjusting cap on the joint 41 to drive the joint 41 to screw into the water outlet 22 to complete the connection and fixation.

[0041] Since the branch pipe 42 connected to the joint 41 will also rotate during the rotation process, a sealing sleeve should be provided on the middle part of the joint 41. The sealing sleeve and the main body of the joint 41 are movably installed and a certain distance is retained. The two ends are sealed with sealing gaskets. A hole is provided on the side wall of the main body of the joint 41. The water transported from the outside will penetrate into the branch pipe 42 through the hole, so that the rotation effect is not affected and the connection structure is maintained. The specific structure can be referred to Figure 5 and Figure 6 shown.

[0042] Furthermore, in the above structure, the branch pipeline 42 should adopt a silicone hose to ensure that it can supply water normally even after being wrapped around the outer wall of the connection.

[0043] A pair of ventilation holes are also provided on the outer wall of the box body 1, one of which is provided with a fan to speed up air circulation, which is conducive to the reproduction of microorganisms and accelerates the aging of tea leaves; the other ventilation hole is provided with a filter to prevent external dust from entering the interior of the box body 1 and causing pollution; a drain pipe is also provided at the bottom of the box body 1 to discharge excess water from the interior of the box body 1.
