By way of instance, tobacco stems may be floor to a fantastic powder and then blended with tobacco mud, guar gum, and water to form an aqueous slurry. This aqueous slurry may be forged and dried to type a reconstituted tobacco sheet. As another, suitable tobacco materials could also be mixed in an agitated tank with water to acquire Fashion tobacco pipe a pulp. This internet is fed onwards to a press, the place the excess water is squeezed out of the web. Figure thirteen illustrates an equipment 30 for the manufacture of a tobacco reduce filler in accordance with the current invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding system 36.
Because of the decreased tobacco fibre size inside the reconstituted tobacco material, exposure to the identical remedies as tobacco lamina might degrade, to some extent, the reconstituted tobacco. By way of instance, during drying, the moisture content of reconstituted tobacco is significantly reduced, leading to shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the chopping methods typically employed to transform the tobacco material mix into filler may end in some lamination and compression of the reconstituted tobacco material. All this causes a discount in the filling power of the treated reconstituted tobacco and, accordingly, of the tobacco minimize filler as a whole. A mode of a discrete likelihood distribution, as is the case with the minimize size distribution among the many reduce strips of the primary tobacco materials is a value at which the likelihood mass perform takes a most value. Thus, in a unimodal distribution, the chance mass perform only has one most worth, and that corresponds to the most probably worth of cut size .
In the embodiment of Figure 10, the two straight parts are substantially perpendicular. The minimize strip of Figure 12 could also be thought to be comprising three V-shaped structures of the sort illustrated in Figure 1 , whereby adjoining V-shaped constructions are linked by the ends of respective straight elements. In the embodiments of each Figures 10 and 12 the sectional minimize width inside all the buildings forming the minimize strips is substantially fixed. A tobacco reduce filler based on any one of the preceding claims, wherein the minimize length distribution among the many minimize strips of the primary tobacco material is ideally unimodal. By means of instance, the cut strip of Figure 9 contains a primary Y-shaped structure together with a first branching node from which a second Y-shaped construction branches off.
More preferably, the first tobacco materials is shredded into strips having a cut width of a minimum of about zero.25 mm. Even more preferably, the primary tobacco materials is shredded into strips having a cut width of no much less than about zero.3 mm. In addition, or as an alternative, the first tobacco material is preferably shredded into strips having a reduce width of lower than about 1 mm.
In turn, the third Y-shaped construction comprises a 3rd branching node from which an oblong structure branches off. In the embodiments of each Figures 9 and 1 1 the sectional minimize width within all the structures forming the cut strips is considerably fixed. By method of example Filling cut tobacco, in a Y-shaped strip it’s potential to determine a first strip portion extending alongside a first course and a second and third strip parts extending from the primary strip parts alongside diverging directions, so that they form an angle.
