  • Patent number: 7934511
    Abstract: The invention relates to a method of processing tobacco fines, whereby the tobacco preparation for producing smoking articles from an initial material to be processed, which contains tobacco fines and tobacco material, is subjected to an increased mechanical pressure in order to bind the tobacco fines permanently to the tobacco material, and no extra or external binding agents are added the material to be processed in order to bind the tobacco fines to the tobacco material. It further relates to smoking articles containing smoking material produced on the basis of one of the methods proposed by the invention.

  • Patent number: 7900639
    Abstract: A reconstituted tobacco material incorporates an exogenous tocopherol or derivative thereof, such as in the amount of at least about 0.1 weight percent. A tobacco blend can be formed by combining reconstituted tobacco material incorporating such an additive with one or more additional tobacco materials, such as burley tobacco, Oriental tobacco, and flue-cured tobacco. A smoking article, such as a cigarette, contains such a reconstituted tobacco, as part of the smokable material, as part of tobacco paper wrapping material, or as part of a reconstituted tobacco-containing filter element. The invention also provides a method of forming reconstituted tobacco material wherein a tocopherol or derivative thereof is added to the tobacco material, either by adding the tocopherol to an aqueous extract or water insoluble pulp formed during the reconstituted tobacco process or by adding the tocopherol to the solid reconstituted tobacco sheet after the aqueous extract and pulp are recombined.

  • Patent number: 6807969
    Abstract: A method of processing reconstituted tobacco which reduces the attrition of reconstituted tobacco and increases the capacity of a primary processing facility by bypassing several conventional primary processing steps. This improved process allows reconstituted tobacco to bypass the primary processing steps up through final cut tobacco drying by separately cutting conventional reconstituted tobacco using a tobacco cutting machine. The method also includes the steps of drying reconstituted tobacco in a pre-dryer, forming sheets of reconstituted tobacco, cutting the sheets to a pre-selected width, transferring the sheets of pre-selected width to a primary processing facility, feeding the sheets of pre-selected width to a tobacco cutting machine, the sheets being cut to a pre-selected size, and blending the pre-selected size cut reconstituted tobacco with conventional cut tobacco.

  • Publication number: 20040177857
    Abstract: Sheet tobacco according to the present invention includes a carrier sheet made of nonwoven plant fibers, and a tobacco powder layer formed on the carrier sheet and containing a powder mixture of tobacco lamina powder and binder powder. In a sheet tobacco manufacturing process according to the present invention, a carrier sheet of plant fibers is formed by a nonwoven fabric production process, a tobacco powder layer is formed by spreading the powder mixture on the carrier sheet, and a cover sheet of plant fibers is optionally formed on the tobacco powder layer. Subsequently, the carrier sheet, the tobacco powder layer and the optical cover sheet are all together subjected to heating and pressing, thereby producing sheet tobacco with a two- or three-layer structure. The present invention also provides a manufacturing system for carrying out the sheet tobacco manufacturing process.

  • Patent number: 6679270
    Abstract: A method for reducing the content of nitrosamines (e.g., N′-Nitrosonornicotine, 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone, N′-Nitrosoanatabine, and N′-Nitrosoanabasine) in tobacco is provided. In one embodiment, the method includes combining tobacco with a solvent (e.g., water and/or other compounds) to form a soluble portion. The soluble portion contains an initial total level of tobacco-specific nitrosamines per gram of the soluble portion. The soluble portion is contacted with a nitrosamine-reducing material such that the resulting weight percentage of the tobacco-specific nitrosamines per gram of said soluble portion is at least about 20% less than the initial total level of the tobacco-specific nitrosamines per gram of the soluble portion.
