Abstract A method is provided for producing shaped tobacco products. Comminuted tobacco material, having an average grain size of up to about 100 Mu is mixed with an aqueous solution having a pH of about 6 to about 10 and containing, in an amount up to about 15 percent by weight of the tobacco material, a substance selected from the group consisting of inorganic base, organic base, alkali metal and ammonium salts and mixtures thereof to form an aqueous slurry. The slurry is subjected to a temperature of not greater than about 100* C. for a period of up to about 45 minutes to form a pulp. To the resulting pulp is added from about 0.5 to about 3 percent by weight based on the weight of the tobacco of a binding agent. Products are shaped from the resulting pulp and the shaped products are dried at a temperature of from about 60* to about 100* C.
substantially dry comminuted tobacco material having an average grain size of up to about 100 Mu , B. subjecting the slurry to a temperature of not greater than 100* C. for a period of about 15 to about 45 minutes to form a pulp, C. adding to the resulting pulp from about 0.5 to about 3 percent by weight based upon the weight of the tobacco of carboxymethyl cellulose or sodium carboxymethyl cellulose, D. forming a shaped product from the resultant pulp by applying said pulp to a substrate, E. drying the resultant shaped product of from about 60* to about 100* C., and F. removing the dried product from the substrate.
