By way of example, tobacco stems could also be floor to a nice powder and then combined with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could additionally be cast and dried to type a reconstituted tobacco sheet. As an alternate, suitable tobacco supplies may be blended in an agitated tank with water to acquire Fashion tobacco pipe a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the online. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the present invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
For instance, a bimodal distribution could correspond successfully to two groups of minimize strips having different average minimize lengths , one group being larger than the other. Preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness of a minimal of about zero.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of a minimal of about 0.1 mm.
In preferred embodiments, the first tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about 0.3 mm, most ideally from a sheet materials having a thickness of about 0.2 mm. A tobacco minimize filler according to any one of claims 1 to 9, wherein the primary tobacco material is shredded into strips each comprising no much less than a primary strip construction comprising a branching node from which an additional strip construction branches off, forming an angle with the primary strip construction. Figures 10 and 12 present two examples of reduce strips including one or more V-shaped structure. Each V construction includes two substantially straight parts forming an angle.
Conventionally, reduce 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 during a threshing course of. Much of the stem portion that is still after the lamina has been removed and separated is not used. However, it is not unusual to add some tobacco stems again into the reduce filler along with the lamina.
In addition, a second couple of blends was used, that contained 70 percent by weight of pure tobacco particles and 30 percent by weight of reconstituted tobacco particles reduce in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the cut width of a person reduce strip is taken on the point alongside the length of the strip that yields the most important cross-sectional area. Further, the filling energy Filling cut tobacco of the shredded first tobacco material could be maximised by deciding on an appropriate first minimize specification. This ends in an improved filling power of the cut filler as a complete, notably when the first tobacco materials is mixed with at least one other tobacco material.
Suitable natural tobacco leaf supplies include tobacco lamina, tobacco stem material and tobacco stalk material. The natural tobacco leaf materials used as the second tobacco material may include any type of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco cut filler according to the current invention includes a primary tobacco material cut in accordance with a primary cut specification, wherein the primary cut specification sets no much less than predetermined first minimize width and first minimize length. The time period “filling energy” is used to explain the volume of space taken up by a given weight or mass of a tobacco material. The greater the filling energy of a tobacco material, the decrease the weight of the material required to fill a tobacco rod of standard dimensions.
The yield of flat rolled stem which can be used directly as filler is increased, and the common stem length and thus the average size of minimize filler from stem is elevated. A tobacco minimize filler in accordance with any one of the preceding claims having a filling power of at least three.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. Accordingly, tobacco particles had been ready from the identical sheet of reconstituted tobacco according to the reduce specification illustrated in Figure 12, whereby the cut width SCW1 is of 0.9 millimetres, the cut length CL1 is of four.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
