The yield of flat rolled stem which can be used directly as filler is increased, and the common stem length and thus the common size of minimize filler from stem is increased. A tobacco cut filler based on any one of many preceding claims having a filling energy of at least 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. Accordingly, tobacco particles had been prepared from the identical sheet of reconstituted tobacco based on the minimize specification illustrated in Figure 12, wherein the cut width SCW1 is of 0.9 millimetres, the reduce size CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
In preferred embodiments, the first tobacco material is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even extra preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness from about 0.1 mm to about 0.three mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco reduce filler according to any one of claims 1 to 9, whereby the primary tobacco materials is shredded into strips each comprising no much less than a primary strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of cut strips together with one or more V-shaped structure. Each V structure includes two considerably straight elements forming an angle.
In addition, a second couple of blends was used, that contained 70 percent by weight of natural tobacco particles and 30 p.c by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the reduce width of an individual reduce strip is taken on the level alongside the length of the strip that yields the biggest cross-sectional area. Further, the filling power of the shredded first tobacco material can be maximised by selecting an appropriate first minimize specification. This ends in an improved filling energy of the cut filler as an entire, notably when the primary tobacco materials is blended with a minimum of one other tobacco material.
By means of example, tobacco stems could also be ground to a fantastic powder after which combined with tobacco mud, guar gum, and water to form an aqueous slurry. This aqueous slurry could also be forged and dried to form a reconstituted tobacco sheet. As an alternate, appropriate tobacco materials could additionally be blended in an agitated tank with water to obtain Fashion tobacco pipe a pulp. This net is fed onwards to a press, where the excess water is squeezed out of the online. Figure 13 illustrates an apparatus 30 for the manufacture of a tobacco minimize 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 gadget 36.
More ideally, the first tobacco material is shredded into strips having a cut width of a minimum of about zero.25 mm. Even more ideally, the primary tobacco material is shredded into strips having a minimize width of a minimum of about 0.three mm. In addition, or in its place, the first tobacco material is ideally shredded into strips having a minimize width of less than about 1 mm.
A tobacco minimize filler based on claim 1 or 2, whereby the primary tobacco material is a pre- processed tobacco material. In a third experiment, the cut specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses involved by the cigarette-making course of. In specific, there was concern that in the course of the cigarette-making process the tobacco particle can be exposed to excessive tensions and frictions which could trigger particles ready in accordance with the minimize specification no. 10 to interrupt. This might have reduced the benefit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco cut filler in accordance with the present invention. Figures depict a quantity of examples of particularly shapes into which tobacco materials for forming a cut filler in accordance with the present invention could also be cut.
Even extra preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about 0.2 mm. In addition, or in its place, the first tobacco material is ideally shredded into strips from a sheet material having a thickness of less than about 1 mm. More ideally, the primary tobacco material is shredded into strips from a sheet material having a thickness of less than about zero.95 mm. Even more ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness of less than about zero.eighty five mm.
The expressions “final reduce width” and “ultimate cut length” are used herein to describe the reduce width and reduce length of a tobacco material as present in a tobacco cut filler utilized in a tobacco product. The method might further comprise a step of conditioning the first tobacco materials previous to cutting the first tobacco materials. Further, the strategy could comprise a step of controlling the moisture content of the minimize filler by adjusting the moisture content material of the primary tobacco material.
More preferably, the first tobacco material is shredded into strips having a reduce width of lower than about 0.ninety five mm. Even more preferably, the first tobacco material is shredded into strips having a minimize width of less tobacco pipe than about 0.9 mm. In most popular embodiments, the first tobacco material is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf material.
Suitable pure tobacco leaf materials embrace tobacco lamina, tobacco stem materials and tobacco stalk materials. The pure tobacco leaf material used as the second tobacco materials might embrace any kind of tobacco leaf, together with for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mix thereof. A tobacco minimize filler according to the current invention comprises a primary tobacco materials reduce in accordance with a first reduce specification, whereby the primary minimize specification sets a minimal of predetermined first reduce width and first cut size. The term “filling energy” is used to explain the quantity of house taken up by a given weight or mass of a tobacco materials. The greater the filling power of a tobacco material, the lower the load of the fabric required to fill a tobacco rod of standard dimensions.
