Method of making a tobacco substitute material
Abstract
Abstract A tobacco substitute is prepared by dry-grinding pieces of nonwoody or low-wood plants to a particle size below 150 microns, thereafter wet-milling the powder to produce a slurry with a particle size of the powder below 50 microns, adding a binder such as sodium carboxymethyl cellulose to the mixture together with a plasticizer and, possibly, mineral fibers and burning controllers. The slurry is cast into a film and dried, preferably with after-moisturization to a final moisture content of the foil between 1 and 15 percent by weight. Any toxic substances contained in the botanicals are removed by steam distillation or solvent extraction prior to forming the composition into a dried film.
