In addition, a second couple of blends was used, that contained 70 % by weight of pure tobacco particles and 30 percent by weight of reconstituted tobacco particles minimize in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the cut width of a person reduce strip is taken on the level along the size of the strip that yields the biggest cross-sectional area. Further, the filling energy tobacco pipe of the shredded first tobacco material could be maximised by selecting a suitable first cut specification. This results in an improved filling power of the cut filler as a whole, significantly when the first tobacco materials is blended with at least another tobacco materials.
The yield of flat rolled stem which can be used immediately as filler is increased, and the common stem length and thus the typical size of reduce filler from stem is elevated. A tobacco reduce filler in accordance with any one of the preceding claims having a filling energy of a minimum of 3.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles had been ready from the identical sheet of reconstituted tobacco in accordance with the cut specification illustrated in Figure 12, wherein the minimize width SCW1 is of 0.9 millimetres, the minimize size CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
The time period “minimize specification” is used all through the specification to check with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco material to a chopping operation. Thus, in accordance to a given “cut specification”, a tobacco materials shall be cut or shredded into strips having a predetermined cut width, cut size, cut shape and so forth. Further, it might be desirable to offer Filling cut tobacco one such improved course of that enables for a greater control of the shape, dimension and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the same time, it will be desirable to supply one such process that doesn’t require any major modification of the conventional apparatus and services used in the main treatment of tobacco.
Further, the second Y-shaped structure comprises a second branching node from which an oblong construction branches off. In the embodiment of Figure 1 1 , the minimize strip includes a first Y-shaped structure including a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction comprises a second branching node from which a 3rd Y-shaped construction branches off.
The minimize width of one such Y-shaped strip corresponds considerably to the distance between the ends of the second and third strip portions as measured alongside a direction perpendicular to the direction defined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional reduce width of each strip portion might as an alternative be measured alongside a path substantially perpendicular to the axis of each strip portion. In some circumstances, corresponding to the place the reduce strip of tobacco materials is substantially rectangular , the sectional minimize width and the strip cut width are the identical.
Alternative methods for the manufacture of reconstituted tobacco sheets are also identified to the skilled person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with an internet, preferably with substantially uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp formed from tobacco particles by one of a number of methods known within the art. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced in the course of the manufacturing process.
Experiments had been carried out to have the ability to assess the influence of various shapes and cut specifications to key parameters of tobacco minimize filler particles, such as the filling power. 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- shaped, it’s possible to measure a wave length of the minimize strip, which substantially corresponds to the strip minimize size divided by the number of repetitions of the zigzag or wave. For occasion , within the cut strip of Figure 1 the zigzag is repeated 10 occasions. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, extra ideally from about 2 mm to about 12 mm, even more ideally from four mm to 10 mm. Preferably, the tobacco reduce filler additional comprises a second tobacco material reduce in accordance with a second minimize specification differing from the first cut specification for no much less than one of minimize length and minimize width.
