A foreign object removal device is provided in the first cavity 11 and is used to remove foreign objects in the tobacco leaves. A large amount of particulate dust will be generated during the process of removing foreign objects from the tobacco leaves. If not removed, it will affect the quality of the tobacco leaves and be harmful to physical health.

[0080] Based on this, negative pressure is provided through the air duct 3, so that the airflow in the first cavity 11 carries dust and enters the second cavity 12 through the air outlet 21, and is discharged through the air duct 3. Since the flow area of the air outlet 21 is adjustable, therefore, the airflow passing through amount from the first cavity 11 into the second cavity 12 can be adjusted, achieving the effect of adjusting the wind pressure, thereby effectively removing dust particles in the tobacco leaves, reducing the diffusion of dust particles, and reducing the harm to the human body, etc.

[0081] In some embodiments, the magnitude of the first wind pressure at the air outlet 21 is detected by the first sensor 71, and the magnitude of the second wind pressure in the air duct 3 is detected by the second sensor 72.
