By way of instance, tobacco stems could additionally be floor to a fantastic powder and then blended with tobacco mud, guar gum, and water to kind an aqueous slurry. This aqueous slurry could also be cast and dried to kind a reconstituted tobacco sheet. As an alternate, appropriate tobacco supplies could also be mixed in an agitated tank with water to acquire tobacco pipe a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the net. Figure 13 illustrates an apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the present invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
The yield of flat rolled stem which may be used directly as filler is elevated, and the common stem length and thus the common length of minimize filler from stem is increased. A tobacco cut filler according to any one of many previous claims having a filling energy of at least three.5 cubic centimetres per gram at a reference moisture worth Filling cut tobacco of 12.5 p.c oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco based on the reduce specification illustrated in Figure 12, wherein the cut width SCW1 is of 0.9 millimetres, the reduce size CL1 is of four.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
Conventionally, cut filler tobacco merchandise for smoking articles are formed predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf during a threshing course of. Much of the stem portion that is still after the lamina has been removed and separated isn’t used. However, it’s not uncommon to add some tobacco stems back into the cut filler along with the lamina.
In follow, one such reduce strip may be described as approximately wave-shaped or zigzag-shaped. Accordingly, geometric parameters corresponding to the height amplitude, peak-to-peak amplitude, interval of a sine wave could also be used to describe the shape of 1 such reduce strips. A tobacco minimize filler contains a primary tobacco materials reduce in accordance with a first reduce specification, whereby the first minimize specification units no much less than predetermined first minimize width and first cut size. A tobacco reduce filler in accordance with any one of the preceding claims, whereby the first tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm.
Further, the second Y-shaped construction contains a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the reduce strip includes a primary Y-shaped structure together with a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure contains a second branching node from which a third Y-shaped structure branches off.
Within a cut strip of tobacco materials, the sectional reduce width may be the considerably identical for all of the strip portions. While this may be preferable, the sectional minimize width can also vary from one strip portion to a different. Typically, prior to being reduce, a tobacco material may endure different mechanical operations, similar to rolling or extrusion.
For example, a bimodal distribution may correspond effectively to two groups of reduce strips having totally different common reduce lengths , one group being larger than the other. Preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of a minimum of about zero.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of at least about 0.1 mm.
In turn, the third Y-shaped structure contains a 3rd branching node from which a rectangular structure branches off. In the embodiments of each Figures 9 and 1 1 the sectional cut width inside all of the structures forming the reduce strips is substantially constant. By method of example, in a Y-shaped strip it’s attainable to identify a first strip portion extending along a primary direction and a second and third strip parts extending from the first strip parts alongside diverging directions, so that they type an angle.
More preferably, the primary tobacco materials is shredded into strips having a minimize width of a minimum of about zero.25 mm. Even more ideally, the primary tobacco materials is shredded into strips having a cut Fashion tobacco pipe width of no less than about zero.three mm. In addition, or instead, the primary tobacco material is preferably shredded into strips having a minimize width of less than about 1 mm.
