  • Patent number: 4867179
    Abstract: A system and method for reclaiming tobacco from rejected products and byproducts of a cigarette manufacturing operation are disclosed. The tobacco that is reclaimed from rejected cigarettes, long ends and defective packs of cigarettes is screened to separate a fraction of larger tobacco particles that can be returned directly to the cigarette manufacturing machines. The fraction of smaller tobacco particles and fines produced by the screening treatment is combined with stem material and tobacco dust recovered from the manufacturing operation to produce strands of reconstituted tobacco which are incorporated into the cut tobacco that is supplied to the cigarette manufacturing machines.

  • Patent number: 4768527
    Abstract: Co-extruded smokable material in sheet-like form has a multi-layered structure. The layers are generally parallel to the major surface of the material. The material is provided by subjecting at least two filler materials to high shear agitation and co-extruding the materials while in a semi-soft state. The multi-layered material can be sized by roll treatment in order to provide a sheet-like material having a thickness of less than about 0.008 inch. In particular, the co-extruded multi-layered smokable material is subjected to compressive treatment applied perpendicularly to the major surface of the co-extruded marterial to provide a co-extruded smokable material of reduced thickness. The material so provided can be cut into small sheets (e.g., about 4 inches by 4 inches square) or into strands and employed as cut filler in the manufacture of cigarettes.

  • Patent number: 4754767
    Abstract: Tobacco material can be processed to yield a product (e.g., sheet-like material) which can be used to yield cut filler for the manufacture of cigarettes. Tobacco material (e.g., whole leaf and/or scrap) is shear agitated in the presence of moisture of less than 30 weight percent. The shear agitation is performed in the absence of externally added binding agents. The sheared mixture is passed through a roller system in order to provide compressive treatment to the mixture. The processed mixture is further formed into the desired shape. Tobacco material can be provided using energy efficient processing steps, and without waste of tobacco material.

  • Patent number: 4674519
    Abstract: A process for making a cohesive tobacco composition in which tobacco pectins within the tobacco itself serve as the binder by contacting dry tobacco particles with a solution, which contains an agent to destroy the alkaline earth metal cross-links of the tobacco pectins, under a high shear condition. A reconstituted tobacco sheet is made by forming the resulting mixture into a sheet and drying. In one embodiment ammonia and tobacco volatiles contained in vapors from the sheet drying step are recovered and recycled into the solution.

  • Patent number: 4589428
    Abstract: A process for maximizing reduction of gas phase components during combustion of tobacco products is disclosed. The process comprises contacting tobacco material with an aqueous solution to form a tobacco extract. After separating the extract from the fibrous tobacco portion, the extract is treated to remove potassium nitrate by ion exchange, electrodialysis, crystallization techniques or the like. Thereafter, potassium ions in the form of a potassium salt other than potassium nitrate are restored to the potassium depleted tobacco and/or extract to a level approximating that originally present in the tobacco prior to extractions.

  • Patent number: 4542755
    Abstract: An improved method of making reconstituted tobacco using a dry-forming process. Fiberized tobacco stems and scrap are combined with tobacco material of a fine particle size. The resulting tobacco mixture is conveyed in an airstream and deposited on a moving foraminous surface. An adhesive is incorporated into or applied to the web bonding the tobacco particles into a coherent sheet, and the sheet is dried if necessary. The dried sheet may be divided into leaflets or shredded for further processing as reconstituted tobacco. In preferred embodiments, cellulose fibers are mixed with the tobacco particles prior to web formation to impart increased sheet strength. In a further embodiment tobacco fines are mixed with the adhesive and applied to the web in the adhesive composition. Results obtained by means of the present invention include cost savings particularly in terms of reduced capital costs.
