In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0038] In the specific use process of this embodiment, when it is necessary to cool the tea leaves, the motor 73 is first started by the external PLC, and the output shaft of the motor 73 rotates to drive the rotating shaft 74 coaxially connected thereto to rotate, and the rotating shaft 74 rotates to drive the coaxially fixed gear 72 on the same side to rotate, and the gear 72 rotates to drive another gear 72 meshing therewith to rotate, and the other gear 72 rotates to drive the rotating rod 71 coaxially fixed thereto to rotate, and the rotating rod 71 rotates to drive the coaxially fixed rotating column 4 on the same side to rotate, and the rotating column 4 rotates to drive the cooling cylinder 3 coaxially fixed thereto to rotate, and the rotation of the cooling cylinder 3 can drive the cover plate 5 fixed thereto to move, and when the cover plate 5 moves to a suitable position, the motor 73 is turned off by the external PLC, and then several screws between the cooling cylinder 3 and the cover plate 5 are unscrewed, and then the cover plate 5 can be disassembled by two handles 8 and two guide blocks 9, and then a proper amount of tea leaves are added to the cooling cylinder 3 through the feeding groove on the outer wall of the cooling cylinder 3, and according to the above, the cover plate 5 can be installed otherwise;

[0039] Then, the motor 73 and several semiconductor refrigeration rods 6 are started by the external PLC. According to the above, after the motor 73 is started, it indirectly drives the cooling cylinder 3 to rotate. The rotation of the cooling cylinder 3 can drive the tea leaves inside it to rotate and turn over. At the same time, several semiconductor refrigeration rods 6 are started to cool, so that they can exchange heat with the tea leaves. During the rotation and turning process, the contact area between the tea leaves and the several semiconductor refrigeration rods 6 is larger, thereby efficiently cooling the tea leaves. After cooling for a period of time, when the cover plate 5 and the discharge trough on the top surface of the working plate 1 are in a suitable relative position, the several semiconductor refrigeration rods 6 and the motor 73 are closed by the external PLC, and then the external collection box is placed on the ground at a position corresponding to the position of the discharge trough on the top surface of the working plate 1. According to the above, the cover plate 5 can be disassembled. After the cover plate 5 is disassembled, the tea leaves cooled in the cooling cylinder 3 can be discharged.
