Alternative strategies for the manufacture of reconstituted tobacco sheets are also identified to the skilled particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with a web, preferably with substantially uniform thickness, which could be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by considered one of a quantity of strategies recognized in the artwork. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced during the manufacturing process.
A tobacco reduce filler in accordance with claim 1 or 2, wherein the primary tobacco materials is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was slightly modified with a view to enhancing the resistance of the particles to the stresses involved by the cigarette-making process. In particular, there was concern that in the course of the cigarette-making process the tobacco particle can be uncovered to high tensions and frictions which might trigger tobacco pipe particles prepared in accordance with the minimize specification no. 10 to break. This could have decreased the benefit coming from the V-shape and proven by the CCV measurements described above. Figure thirteen depicts a schematic view of an apparatus for forming a tobacco minimize filler in accordance with the present invention. Figures depict several examples of significantly shapes into which tobacco material for forming a reduce filler in accordance with the current invention could additionally be minimize.
The expressions “final cut width” and “ultimate reduce size” are used herein to describe the reduce width and minimize length of a tobacco material as found in a tobacco cut filler used in a tobacco product. The methodology may further comprise a step of conditioning the primary tobacco materials prior to cutting the first tobacco materials. Further, the strategy may comprise a step of controlling the moisture content material of the reduce filler by adjusting the moisture content material of the primary tobacco materials.
In some embodiments, tobacco reduce filler based on the invention may be used in the tobacco rod of a flamable smoking article, corresponding to a filter cigarette, cigarillo or cigar. Alternatively, the reduce filler could also be used to offer the tobacco aerosol generating substrate in a distillation based mostly smoking article, or an electrically heated smoking system. Alternatively, the reduce filler may be used as a roll-your-own or make-your-own product, or unfastened tobacco product for use in a pipe.
Reconstituted tobacco is shaped from tobacco material similar to tobacco stems, tobacco stalks, leaf scraps and tobacco mud, that are produced in the course of the manufacturing processes of tobacco merchandise. Such tobacco material might, for example, be floor to a fantastic powder and then blended with water and usually with a binder, such as guar gum, to kind a slurry. This slurry is then cast onto a supportive floor, such as a belt conveyor, and dried to type a sheet (so called ‘forged leaf) that can be removed from the supportive surface and wound into bobbins.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 percent by weight of reconstituted tobacco particles minimize in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the minimize width of a person minimize strip is taken on the level alongside the length of the strip that yields the largest cross-sectional space. Further, the filling power of the shredded first tobacco materials can be maximised by deciding on an acceptable first reduce specification. This results in an improved filling power of the reduce filler as an entire, significantly when the primary tobacco material is mixed with a minimum of another tobacco materials.
Experiments were carried out so as to assess the impact of different shapes and minimize specs to key parameters of tobacco cut filler particles, such because the filling energy. In more element, Figure 1 exhibits a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- formed, it is possible to measure a wave length of the minimize strip, which considerably corresponds to the strip reduce length divided by the variety of repetitions of the zigzag or wave. For occasion, within the cut strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave length of the sinusoidal shape is from about 1 mm to about 15 mm, extra ideally from about 2 mm to about 12 mm, even more preferably from 4 mm to 10 mm. Preferably, the tobacco cut filler further includes a second tobacco materials minimize in accordance with a second cut specification differing from the primary minimize specification for at least one of minimize length and reduce width.
