Abstract
Tobacco is reconstituted to provide a product of tobacco-filler size particles. Particulate tobacco, starch, 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. While in the plastic phase, the extrudate is subjected to a draw down step. The extrudate is then cut to particle size.
