Abstract (en)
[origin: US5060670A] The present invention describes a method and an apparatus for blowing cut tobacco material, wherein a stream of a carrier gas and entrained tobacco ribs is surrounded in a flow channel section at least at one point by a hot gas stream separately introduced and accelerating the afore-mentioned mixed stream. The acceleration is preferably effected at several successive points. The cover stream is introduced through annular jets, the cross-section of the flow channel remaining constant along the entire extent of the flow channel section.
