In addition, the formation of tobacco mud is reduced compared with traditional manufacturing methods. Accordingly, the necessity to collect and re-process tobacco dust is significantly lowered and the general effectivity of the manufacturing process is thus advantageously increased. A tobacco minimize filler in accordance with any one of many previous claims, wherein the primary tobacco material is shredded into strips having a sinusoidal form, whereby a wave length of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco cut filler in accordance with any one of the previous claims, whereby the first tobacco materials is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Table 2 below lists the values of CCV measured at a reference moisture worth of 12.5 percent oven volatiles for each sample.
In turn, the third Y-shaped structure includes a third branching node from which a rectangular construction branches off. In the embodiments of both Figures 9 and 1 1 the sectional minimize width inside all of the constructions forming the minimize strips is considerably constant. By way of instance, in a Y-shaped strip it is possible to determine a primary strip portion extending along a first path and a second and third strip parts extending from the first strip parts alongside diverging instructions, in order that they type an angle.
Preferably, the first tobacco material is shredded into strips wherein the minimize size is larger than the cut width. Further, when reconstituted tobacco undergoes the same treatments as tobacco lamina, a major quantity of tobacco dust is formed. Besides, in the interest of process economic system, it is fascinating that the tobacco dust be reprocessed in some type or other to extend the overall effectivity.
Where OV is the actual % oven volatiles of the sample of tobacco minimize filler and f is a correction issue (0.four for the take a look at indicated). In RYO, the stem can either be separated from the lamina by hand (for hand-stripped tobacco) or the stem and lamina are not separated at all (loose-leaf tobacco) – this type is used for Scandinavian Tobacco Group’s Norwegian RYO brand Tiedemanns. A method based on any certainly one of claims 15 to twenty, additional comprising adjusting the moisture content of the second tobacco material. A fishbone-shaped strip is proven in Figure 6, whereas Figures 7 and 8 show two embodiments of rectangular strips. Abstract The quantity of tobacco which is critical for the correct filling of a cigarette depends on various factors and significantly on the filling weight of tobacco rag at a given pressure. Some years in the past the ”Centre d’Essais” of the SEITA developed an apparatus by which the filling weight being associated to the filling capacity could be measured.
In the embodiment of Figure 10, the 2 straight elements are considerably perpendicular. The reduce strip of Figure 12 could additionally be thought to be comprising three V-shaped structures of the sort illustrated in Figure 1 , wherein adjoining V-shaped constructions are connected by the ends of respective straight components. In the embodiments of both Figures 10 and 12 the sectional reduce width inside all of the constructions forming the minimize strips is considerably constant. A tobacco reduce filler according to any one of the previous claims, wherein the minimize size distribution among the minimize strips of the primary tobacco materials is preferably unimodal. By way of example, the cut strip of Figure 9 comprises a primary Y-shaped structure together with a first branching node from which a second Y-shaped structure branches off.
Within a cut strip of tobacco materials, the sectional cut width could be the considerably identical for all of the strip portions. While this can be preferable, the sectional reduce width may also tobacco pipe vary from one strip portion to another. Typically, previous to being cut, a tobacco material might bear different mechanical operations, similar to rolling or extrusion.
More ideally, the primary tobacco materials is shredded into strips having a reduce width of at least about 0.25 mm. Even more preferably, the first tobacco materials is shredded into strips having a reduce Fashion tobacco pipe width of at least about 0.3 mm. In addition, or instead, the primary tobacco materials is ideally shredded into strips having a minimize width of lower than about 1 mm.
Conventionally, reduce filler tobacco products for smoking articles are formed predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing process. Much of the stem portion that is still after the lamina has been eliminated and separated is not used. However, it isn’t uncommon to add some tobacco stems again into the reduce filler along with the lamina.
By means of instance, tobacco stems may be floor to a nice powder after which blended with tobacco mud, guar gum, and water to form an aqueous slurry. This aqueous slurry could also be cast and dried to form a reconstituted tobacco sheet. As an alternative, appropriate tobacco supplies could additionally be blended in an agitated tank with water to obtain a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the online. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco cut filler in accordance with the current invention. A internet 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
