It should be further noted that as shown in fig. 7 and 16, after the vegetable leaves 4 are integrally arranged on the plurality of sets of rotating rollers b3241, the rotating shaft 315 is disengaged from the limiting plate 318, then the gear b3232 passes through the rack set 3244, and the gear b3232 rotates forward and backward, so as to drive the rotating rollers b3241 to rotate forward and backward, so that the vegetable leaves 4 move back and forth, and the overall drying effect of the vegetable leaves 4 is improved.

It should be further noted that in the process that the material receiving assembly 32 moves to cooperate with the gear set 3244, when the gear b3232 cooperates with the first rack d32441, the rotating roller b3241 drives the vegetable leaves 4 to move in a direction away from the heat insulation box 321, and the vegetable leaves 4 do not enter the heat insulation box 321 again.
