4944316	Process for treating tobacco and similar organic materials In order to effect expansion of a shredded material, said material is impregnated with an inert organic liquid, which is subsequently vaporized. The major portion of the impregnation agent is removed by separation. In order to eliminate the residual amoun...	07/31/1990
4766912	Method and apparatus for puffing tobacco Fragments of tobacco ribs are puffed in an elongated tunnel which is vibrated to advance the particles from the inlet toward the outlet. The particles in the tunnel are contacted by streamlets of supersaturated or superheated steam at such temperature and...	08/30/1988
4574819	Process for increasing the filling power of tobacco Cut tobacco is treated with a supersaturated aqueous solution of calcium citrate and excess moisture is removed. The result is a significant increase in the filling power of the cut tobacco....	03/11/1986
4532945	Process for increasing and maintaining the filling power of tobacco A process for increasing and maintaining the filling power of tobacco, in which an effective amount of at least one cross-linking agent is applied to the tobacco and reacted with various components therein. The cross-linking agent may be applied directly ...	08/06/1985
4497330	Process for increasing the filling power of tobacco The present invention relates to a process for increasing the filling power of tobacco which comprises heating the tobacco at elevated temperature while maintaining the OV and SV values of the tobacco substantially constant. Preferably, the tobacco is hea...	02/05/1985
4485829	Process for increasing the filling power of tobacco A process is disclosed for increasing the filling power of tobacco by contacting the tobacco, preferably by dry blending, with at least one basic calcium compound in an amount such that the treated tobacco has a pH of at least about 8, and heating the tob...	12/04/1984
4388932	Process for improving filling power of expanded tobacco Tobacco which has been increased in filling power by a conventional tobacco expansion process can be further increased in filling power by a post expansion heat treatment. The post expansion heat treatment comprises contacting the expanded tobacco produce...	06/21/1983
4388933	Tobacco stem treatment and expanded tobacco product An improved process for expanding tobacco is disclosed wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution and thereafter dried and roasted to produce an expanded tobacco material highly su...	06/21/1983
4366824	Process for expanding tobacco An improved process for expanding tobacco is disclosed wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution to effect expansion, washed and then dried and/or roasted to produce an expanded t...	01/04/1983
4366823	Process for expanding tobacco An improved process for expanding tobacco wherein tobacco components such as stems, midribs and veins are contacted with an alkaline-hydrogen peroxide solution to effect expansion, washed and then dried and/or roasted to produce an expanded tobacco materi...	01/04/1983
4333482	Process for increasing filling power of reconstituted tobacco A method for increasing the filling power of sheet or shredded reconstituted tobacco which is normally not susceptible to conventional expansion techniques is provided. In the practice of the method reconstituted tobacco having a uniform moisture content ...	06/08/1982
4274427	Method of increasing filling power of tobacco products Through interaction with the pectinaceous materials of tobacco smoking products, increased filling power of tobacco constituents is accomplished, in accordance with the present invention, by means of maintaining the tobacco, usually in shredded form, in a...	06/23/1981
4202357	Reordering expanded tobacco by water mist A process for rapidly and uniformly reordering tobacco material which has been subjected to an expansion treatment is disclosed. The process comprises spraying the tobacco material with a fine water mist characterized by an average droplet size of between...	05/13/1980
4195647	Method and apparatus for increasing the volume of tobacco or the like Shreds of tobacco are conveyed across a rising stream of saturated steam and in a shower of hot water droplets so that the temperature and moisture content of shreds increase to a value at which the shreds are pliable. The shreds are thereupon introduced ...	04/01/1980
4167191	Tobacco drying process The disclosure is of a process for reducing the moisture content of expanded tobacco while minimizing yield losses and reducing particle lamination while maintaining filling power. The process comprises drying the expanded tobacco at a temperature within ...	09/11/1979
4161953	Method of puffing tobacco tissue Tobacco tissue is puffed by admixing with it hot water, preferably in the form of droplets, in amounts which are substantially completely absorbed by the tobacco in five minutes or less and thus cause puffing of the tobacco cell walls, and freeze drying t...	07/24/1979
4072155	Stiffening of tobacco with dialdehyde The stiffness of tobacco is increased by treating tobacco with a dialdehyde. The treatment is carried out in the presence of a suitable catalyst.
