Suitable natural tobacco leaf materials embody tobacco lamina, tobacco stem material and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco material could embody any kind of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco reduce filler according to the current invention includes a first tobacco materials reduce in accordance with a first tobacco pipe minimize specification, wherein the primary cut specification sets no much less than predetermined first reduce width and first minimize size. The term “filling energy” is used to explain the quantity of space taken up by a given weight or mass of a tobacco material. The higher the filling energy of a tobacco materials, the lower the weight of the fabric required to fill a tobacco rod of ordinary dimensions.
More preferably, the reduce filler has a filling energy of lower than about 7 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In some particularly preferred embodiments, the minimize filler has a filling power of from about 3.5 cubic centimetres per gram to about eight cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Preferably, the first tobacco material is shredded into strips having a cut length of no less than about 5 mm. More ideally, the primary tobacco materials is shredded into strips having a reduce size of no less than about 10 mm.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing parts of the particles would still be effectively V-shaped. The highest CCV values have been obtained for minimize specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was found that when particles had been produced from the same sheet of reconstituted tobacco in accordance with minimize specification no. three are produced, a major fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed in the Fashion tobacco pipe following Table 3 were measured. Tobacco reduce fillers in accordance with the present invention may be ready by a technique comprising offering a primary tobacco material and chopping the first tobacco material in accordance with a primary reduce specification setting a minimal of predetermined first cut width and first cut length. Tobacco cut filler in accordance with the current invention may be included into quite a lot of smoking articles.
In follow, one such reduce strip could also be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters comparable to the peak amplitude, peak-to-peak amplitude, interval of a sine wave may be used to explain the shape of 1 such cut strips. A tobacco cut filler includes a primary tobacco materials cut in accordance with a primary minimize specification, wherein the first cut specification units no less than predetermined first minimize width and first minimize length. A tobacco reduce filler according to any one of the previous claims, wherein the first tobacco material is shredded into strips having a reduce width from about 0.2 mm to about 1 mm.
Where OV is the actual p.c oven volatiles of the pattern of tobacco reduce 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 usually are not separated at all (loose-leaf tobacco) – this form is used for Scandinavian Tobacco Group’s Norwegian RYO model Tiedemanns. A method in accordance with any considered one of claims 15 to twenty, additional comprising adjusting the moisture content material of the second tobacco material. A fishbone-shaped strip is shown in Figure 6, whereas Figures 7 and eight present two embodiments of rectangular strips. Abstract The amount of tobacco which is necessary for the correct filling of a cigarette depends on different factors and particularly on the filling weight of tobacco rag at a given stress. Some years ago the ”Centre d’Essais” of the SEITA developed an equipment by which the filling weight being associated to the filling capability could be measured.
In turn, the third Y-shaped structure includes a 3rd branching node from which an oblong structure branches off. In the embodiments of each Figures 9 and 1 1 the sectional reduce width inside all of the constructions forming the reduce strips is considerably constant. By means of instance, in a Y-shaped strip it’s potential to identify a primary strip portion extending along a primary course and a second and third strip parts extending from the primary strip portions along diverging directions, so that they kind an angle.
More ideally, the primary tobacco materials is shredded into strips having a cut width of less than about 0.95 mm. Even more ideally, the first tobacco materials is shredded into strips having a reduce width of less Filling cut tobacco than about 0.9 mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
As the name implies, it’s merely a mix of completely different tobacco types, cuts and flavors. They are simple to fill and smoke, and have higher robustness and style variety than loose cut tobacco by itself. The first tobacco materials may be minimize into strips having any suitable shape, including rectangular, trapezoidal, sinusoidal, Y-shaped, X-shaped and V-shaped.
By method of instance, tobacco stems could also be floor to a fantastic powder and then blended with tobacco mud, guar gum, and water to form an aqueous slurry. This aqueous slurry could additionally be cast and dried to kind a reconstituted tobacco sheet. As an alternative, suitable tobacco supplies could also be combined in an agitated tank with water to obtain 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 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 system 36.
