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.

Claims

2. A method as in claim 1 wherein the tobacco material is selected from the group consisting of cured and partially cured tobacco.

3. A method as in claim 1 wherein tobacco waste arising in the tobacco industry is utilized.

4. A method as in claim 1 wherein the shaped product is a sheet.

5. A method as in claim 4 wherein, prior to removal of the dry sheet from the substrate, said sheet is sprayed with an aqueous softener solution.

6. A method as in claim 5 wherein the softener is an aqueous solution of a member of the group consisting of glycerol, sorbite, and diethylene glycol and mixtures thereof.

7. A method as in claim 4 wherein the pulp sheet has a thickness of about 0.5 mm.

8. A product produced in accordance with the method of claim 1.
