20080245379Method and Equipment for Adding Tobacco Dust into Papermaking Tobacco Sheet - This invention discloses a method for adding tobacco dust in production process of the papermaking tobacco sheet and its equipment. The tobacco dust is added in 5-30% weight at four process points such as the pipeline from the slurry stabilization box to the slurry flow box, the long-net of the papermaking machine, the position from the vacuum couch to the first press, and the coating position on the papermaking machine. This invention adopts a method for adding the tobacco dust in production process of papermaking tobacco sheet, which has well improved its physical performances including the filling capacity of the papermaking tobacco sheet and solved smoking problems of the papermaking tobacco sheet, such as worse inherent quality, heavy stemy note, insipid tobacco aroma and etc. In addition, this method has also offered a good way to well utilize tobacco dust resource in sizes of 2 mm-100 mesh, which is abnegated in cigarette production, to save resource and to reduce the cigarette cost.10-09-2008
20080216854Methods of making reconstituted tobacco sheets - A reconstituted tobacco sheet having a high content of aerosol former therein is manufactured by preparing an aqueous slurry containing a tobacco material which is formed into a sheet. The moisture content of the sheet can be reduced to less than about 50% by weight before incorporating an aerosol former such as glycerin, which can be at a temperature below about 40° C., followed by drying the sheet. The sheet can be trashed, blended with natural tobacco strips, and shredded into a cut filler of a smoking article.09-11-2008

20110214681PROCESS FOR PREPARING SNUFF COMPOSITION - A method for the preparation of a nicotine-cellulose combination, the method comprising simultaneous loading of the nicotine on the cellulose and agglomeration of the particles so as to obtain a suitably loaded combination with a mean particle size that is suitable for use e.g. in snuff compositions packed in pouches of gauze or other materials with opening. The invention further relates to the use of such a nicotine-cellulose combination for the preparation of a snuff composition for achievement of a fast onset of action of nicotine after application of the snuff composition to the oral cavity of a subject, wherein the composition has a high release rate so that when subjected to an in vitro dissolution test about 45% or more of the total content of nicotine is released within 30 minutes. Moreover, the invention relates to an improved snuff composition for application to the oral cavity.09-08-2011
