Abstract: 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.

Abstract: The application relates to a conveying arrangement for a machine in the tobacco-processing industry having a conveying apparatus which has a plurality of conveying elements moving in a conveying direction for conveying and/or separating a fibrous product and is characterised in that in the region of the conveying elements the conveying arrangement comprises at least one fixed nozzle for blowing in a medium in a direction counter to the conveying direction.

Abstract: The application relates to an apparatus for conditioning a tobacco product having a transport pipe through which a process gas flows and which has a feed section having a feed opening for feeding in the product and a following drying section, characterised in that the transport pipe has dividing means for dividing, before the feed opening, the stream of process gas into a substream picking up the product and a substream which is substantially product-free and for bringing the substreams together at the beginning of the drying section so that the product is introduced into the drying section in the inner region of the transport pipe.

Abstract: A shower of tobacco particles is admitted into the inlet at the top of and descends by gravity and/or under the action of a driven cell wheel in a generally upright duct. The particles are moisturized prior to admission into the duct or due to contact with droplets of water in the inlet, and are thereupon caused to traverse an orbiting shower of steam, water and/or another conditioning medium in an intermediate portion of their path in the duct. Such treatment entails a swelling and thus increases the volume of the particles. The conditioning medium is discharged via orifices radially outwardly from at least one substantially horizontal conduit which is rotated about its axis and can be provided with external pins or analogous mechanical impellers serving to cause the particles of tobacco to orbit about the conduit prior to descending into the range of a dryer at a level below the intermediate portion of the path, e.g., at the outlet of the duct.
