Abstract
Tobacco is reconstituted to provide a product of tobacco-filler size particles. Particulate tobacco, from 5 to 10 weight percent of starch, up to 10 weight percent binder and water are fed to an extruder, the operating conditions being such that in the sheet form extrudate water flashes off to steam, thus to expand the extrudate. Further, the cross-section of the extrudate when exiting the orifice of the extruder expands to a cross-section greater than that of the orifice of the extruder. After being cooled, the extrudate is cut to particle size. The particles, each of which comprises a cellular interior and a skin at two opposite sides, can be used as or in cigarette filler.
