Note that, as shown in fig. 14, the rotation of the rotating roller a3231 can be used for feeding the heat insulating box 321.

When the heat insulation box 321 moves with the vegetable leaves 4, the leaf stalks 42 are in a naturally drooping state.

It should be noted that, as shown in fig. 11 and 14, after the blade 41 enters the heat insulation box 321, the conveying assembly b22 conveys the heat insulation box 321 and the vegetable leaves 4 to the preheating zone 11 for preheating, and then when the heat insulation box 321 and the vegetable leaves 4 enter the drying zone a12 for drying, the gear a316 is engaged with the rack a317, so as to drive the heat insulation box 321 and the drying table 322 to rotate, so as to drive the blade handle 42 to rotate for drying, and the blade handle 42 is heated more uniformly, so as to achieve a better drying effect.

It should be noted that, as shown in fig. 15, after the heat insulation box 321 and the vegetable leaves 4 leave the drying zone a12 along with the conveying of the conveying assembly b22, the drying platform 322 rotates upward, and the leaf stalks 42 fall onto the drying platform 322.
