Advantageously, the disc edges 104 on one side are uniformly distributed up and down, the disc edges 104 on the left side and the right side are arranged in a staggered manner, and the disc edges 104 can be switched between the left side and the right side more conveniently through the staggered arrangement.

The implementation principle is as follows: when the tea leaves are tedded, a user uniformly spreads the white tea leaves on the tray 105, at this time, the driving motors 121 on the left and right sides are started to drive the threaded rod 123 to rotate, in this process, the lifting slide blocks 143 in the lifting slide grooves 122 are restrained by the rotation of the inner wall of the lifting slide grooves 122, and then the lifting slide blocks 143 in threaded connection with the threaded rod 123 are driven to ascend (descend) when the threaded rod 123 rotates, when the lifting slide blocks 143 ascend to the maximum extent and the guide slide blocks 126 slide into the clamping grooves 132 to the maximum extent, the lower end surfaces of the lifting slide blocks 143 are flush with the lower inner wall of the switching communication groove 111, at this time, the switching motor 141 is started to drive the switching rotary block 133 to rotate through the gear 142, and further drive the lifting slide blocks 143 to slide through the switching communication groove 111 into the lifting slide grooves 122 on the other side, and the position of the threaded rod 123 on the left side and the right side is adjusted and the switching rotating block 133 is rotationally matched, so that the lifting slide block 143 on one side is in threaded connection with the threaded rod 123 on the other side, at the moment, the switching on the left side and the right side is completed, at the moment, the threaded rod 123 on the left side and the right side continuously rotates, the disc edge 104 on one side can be lifted, the disc edge 104 on the other side is lowered, and the circular coiling is carried out.

The invention has the beneficial effects that: in the embodiment, the fragrance and the taste of the tea can be improved by adding the laccase solution, and the drying uniformity of the tea distributed up and down can be greatly improved by the circulating movement of the drying rack when the tea is tedded in the sunlight of white tea, so that the water content of the Chinese cabbage is guaranteed.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
