Method and device for removing foreign bodies from a first tobacco stream that is conveyed via an air flow in a region of a first foreign body detection device. Method includes detecting, with a first foreign body detection device, the foreign bodies in the first tobacco stream based on at least one property, and removing, with a jet of compressed air, the foreign bodies from the first tobacco stream. In this manner, a foreign body freed tobacco stream and a second tobacco stream including tobacco particles and the foreign bodies entrained by the jet of compressed air are formed. Method also includes at least one of: accelerating the second stream at a distance from the first tobacco stream; and detecting, with a second foreign body detector, foreign bodies in the second stream based on at least one property and removing the detected foreign bodies with a second jet of compressed air.
