Within a cut strip of tobacco material, the sectional minimize width may be the substantially same for all the strip portions. While this can be preferable, the sectional reduce width can also differ from one strip portion to another. Typically, previous to being cut, a tobacco materials might undergo different mechanical operations, corresponding to rolling or extrusion.
Conventionally, minimize filler tobacco products for smoking articles are fashioned predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf throughout a threshing course of. Much of the stem portion that remains after the lamina has been eliminated and separated just isn’t used. However, it isn’t unusual to add some tobacco stems back into the cut filler together with the lamina.
More ideally, the primary tobacco materials is shredded into strips having a minimize width of no much less than about 0.25 mm. Even more ideally, the first tobacco materials is shredded into strips having a cut width of no much less than about 0.three mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips having a cut width of less than about 1 mm.
A tobacco reduce filler based on any one of the preceding claims, whereby the first tobacco material is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco cut filler in accordance with any one of claims 2 to four, wherein the second tobacco material is a pure tobacco leaf material. An angle of 90 degrees was thought of to be undesirable, in that it might lead basically to a form fairly much like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the method ideally comprises the step of blending the reduce first tobacco material and the reduce second tobacco materials.
A tobacco minimize filler in accordance with declare 1 or 2, whereby the first tobacco materials is a pre- processed tobacco materials. In a 3rd experiment, the reduce specification no. 10 was barely modified with a view to enhancing the resistance of the particles to the stresses concerned by the cigarette-making process. In particular, there was concern that through the cigarette-making process the tobacco particle can be exposed to excessive tensions and frictions which could trigger particles prepared in accordance with the minimize specification no. 10 to break. This could have reduced the profit coming from the V-shape and shown by the CCV measurements described above. Figure thirteen depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the present invention. Figures depict several examples of notably shapes into which tobacco material for forming a minimize filler in accordance with the present invention may be minimize.
For instance, a bimodal distribution might correspond effectively to 2 teams of minimize strips having completely different common reduce lengths , one group being larger than the other. Preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of at least about zero.05 mm. More ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness of a minimum of about 0.1 mm.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of a person minimize strip is taken on the point along the length of the strip that yields the biggest cross-sectional area. Further, the filling energy of the shredded first tobacco material may be maximised by selecting an appropriate first reduce specification. This leads to an improved filling energy of the minimize filler as a complete, significantly when the primary tobacco material is mixed with no much less than one other tobacco materials.
The shredding device is configured to chop the reconstituted tobacco in accordance to a primary minimize specification, whereby each minimize width and cut size are predetermined. The minimize strips are dropped onto a conveyor belt 38 organized beneath the shredding system 36 and defining a collection surface upon which the minimize strips fall out of the shredding device. Additional means T may be supplied for tensioning the online of reconstituted tobacco as it’s Filling cut tobacco unwound off the bobbin. Further, the apparatus 30 may comprise sensors forty for detecting the moisture content of the online of reconstituted tobacco upstream of the shredding device 36. In addition, the equipment 30 may comprise mass flow controllers 42, forty four adapted to adjust the speed at which the web of reconstituted tobacco is fed to the shredding gadget 36 and the pace of the conveyor belt 38.
By way of instance, tobacco stems may be ground to a nice powder after which blended with tobacco dust, guar gum, and water to form an aqueous slurry. This aqueous slurry may be cast and dried to kind a reconstituted tobacco sheet. As an alternate, appropriate tobacco materials may be mixed in an agitated tank with water to acquire a pulp. This net is fed onwards to a press, where the excess water is squeezed out of the web. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco minimize filler in accordance with the current invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
