Example Embodiment
[0033] Example 1
[0034] like figure 1 As shown, an internal flow tobacco dryer described in this embodiment includes a cylinder body 2, a feed end 1 and a discharge end 4, and the cylinder body 2 is rotatably arranged at the feed end 1 and the discharge end between 4. The tobacco material enters the cylinder 2 from the feed end 1, and flows out from the discharge end 4 after being dried. Inside the cylinder 2 is a central pipe 5 for drying the tobacco. The central pipe 5 runs through the cylinder 2 and its two ends are fixedly installed on the feeding end 1 and the discharging end 4 respectively. The discharge end 4 is provided with a drying gas inlet, and the drying gas enters the central pipe 5 through the drying gas inlet. The lower part of the central pipe 5 is evenly distributed with which the drying gas can be discharged and act on the tobacco material which is always at the bottom of the cylinder body 2 .

Example Embodiment
[0039] Embodiment 2
[0040] like figure 1 As shown in the figure, an internal flow tobacco dryer described in this embodiment is mainly composed of a cylinder body 2, a feeding end 1, a discharging end 4, a central pipe 5, a branch pipe 7, a moisture removal device 3, and a management and control system. 12. The drive device 11, the heat exchanger 10, the fan 9 and the supporting legs 8 are composed. Wherein, the cylinder 2 is located between the feeding end 1 and the discharging end 4 and rotates under the driving of the driving device 11 , and the central pipe 5 and the branch pipes 7 do not rotate with the cylinder 2 . The rotation of the cylinder body 2 enables the tobacco material at the bottom of the cylinder body 2 to fully contact the drying gas discharged from the branch pipe 7, thereby achieving the purpose of more adequate drying.
[0041] In this embodiment, the central pipe 5 runs through the interior of the cylinder body 2 and includes a first central pipe 51 ...
