The heat insulation wall 2 can be a wall structure or a heat insulation plate.
Therefore, when the circulation fan 6 blows upward, each of the small dehumidification pipes 8a faces the heat exchanger 7; when the circulation fan 6 blows down, each of the small moisture removal tubes 8a faces the lower ventilation gap 12. The circulating fan 6 alternately rotates forward and reverse, so that the flow of the moisture can be changed from top to bottom and from bottom to top to alternately resurgence the tobacco leaves, thereby making resurgence more uniform. And, the steering engine 9 is connected axially to the dehumidification pipeline 8 to make the dehumidification pipeline 8 turn to according to the direction of blowing of circulating fan 6, realize the orientation of each dehumidification tubule 8a on the synchronous adjustment dehumidification pipeline 8, with the dehumidification characteristic unanimity when circulating fan 6 corotation and reversal, thereby effectively promote the efficiency of resurgence.

where dy (t) represents the water absorption at the time of tobacco leaf t, mz (t) represents the measured value at the time of weighing sensor t, mz (0) represents the measured value at the time of weighing sensor initial, and mj represents the mass of tobacco holder.
Referring to fig. 8 and 9, in step S4, the target relative humidity curve is a step curve or a linear curve with constant slope. When the humidity sensor is not high in measurement accuracy (for example, the error is higher than 3%), a step curve is adopted, and when the humidity sensor is high in measurement accuracy (for example, the error is lower than 3%), a linear curve is adopted.

In the control of the conditioning process, the control period T is kept unchanged, and the running time Tr and the stopping time Ts are adjusted according to actual needs, and the step length is adjusted to be Td.
For example, the control period t=300s, td=30s, the running time tr=90s at a certain time, the stop time ts=210 s, and if the actual humidity is high, the next control period increases the stop time, i.e., tr=60 s, and the stop time ts=240 s according to the decrease of the running time.
On the other hand, the ambient temperature and humidity are collected, and if the ambient temperature is higher than the temperature in the curing barn, the humidifier is turned off when the ambient humidity is higher than the target curing barn humidity, namely, t=ts, tr=0.
Referring to fig. 11, the circulating fan 6 and the steering engine 9 are synchronously controlled. The circulating fan 6 performs steering control, and the forward rotation and the reverse rotation run in turn, and the forward rotation time and the reverse rotation time are the same; the steering engine 9 performs angle control, and when the direction of the circulating fan 6 changes, the direction of the moisture discharging port is adjusted to be consistent with the direction of the air flow.
