Suitable pure tobacco leaf materials include tobacco lamina, tobacco stem materials and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco materials could include any kind of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mix thereof. A tobacco cut filler based on the present invention includes a first tobacco materials reduce in accordance with a primary minimize specification, whereby the first reduce specification units at least predetermined first cut width and first reduce size. The time period “filling energy” is used to describe the amount of area taken up by a given weight or mass of a tobacco material. The higher the filling power of a tobacco material, the decrease the weight of the fabric required to fill a tobacco rod of ordinary dimensions.
The time period “reduce specification” is used throughout the specification to discuss with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco material to a slicing operation. Thus, in accordance to a given “cut specification”, a tobacco materials shall be minimize or shredded into strips having a predetermined reduce width, minimize size, reduce shape and so forth. Further, it will be fascinating to provide one such improved course of that allows for a greater management of the shape, measurement and properties of the reconstituted tobacco matter forming a part of the minimize filler. At the same time, it might be fascinating to offer one such course of that does not require any major modification of the standard apparatus and services used within the primary remedy of tobacco.
A tobacco minimize filler according to any one of the previous claims, wherein the primary tobacco material is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling energy of at least about 3.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. More ideally, the cut Filling cut tobacco filler has a filling energy of a minimal of about 4 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. In addition, or in its place, the reduce filler preferably has a filling energy of less than about eight cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles.
Even more preferably, first tobacco materials is shredded into strips having a cut size of at least about 15 mm. In addition, or in its place, the first tobacco material is preferably shredded into strips having a reduce size of lower than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a cut length of less than about 50 mm. Even extra ideally, the first tobacco materials is shredded into strips having a reduce size of less than about forty mm. In most well-liked embodiments, the first tobacco materials is shredded into strips having a reduce size from about 5 mm to about 60 mm. The time period “sectional minimize width” is used within the present specification to explain the side- to-side width of one such portion of a cut strip of tobacco materials.
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 cut strip contains a first Y-shaped structure together tobacco pipe with a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure includes a second branching node from which a third Y-shaped structure branches off.
More preferably, the primary tobacco materials is shredded into strips having a cut width of no much less than about zero.25 mm. Even extra ideally, the first tobacco material is shredded into strips having a minimize width of at least about 0.three mm. In addition, or as an alternative, the first tobacco materials is preferably shredded into strips having a cut width of less than about 1 mm.
Experiments had been carried out to have the ability to assess the impact of various shapes and minimize specifications to key parameters of tobacco reduce filler particles, such as the filling energy. In more detail, Figure 1 reveals a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- formed, it’s attainable to measure a wave length of the reduce strip, which substantially corresponds to the strip cut length divided by the number of repetitions of the zigzag or wave. For instance, within the cut strip of Figure 1 the zigzag is repeated 10 occasions. Preferably, a wave size of the sinusoidal form is from about 1 mm to about 15 mm, extra preferably from about 2 mm to about 12 mm, even more ideally from 4 mm to 10 mm. Preferably, the tobacco reduce filler additional includes a second tobacco materials reduce in accordance with a second cut specification differing from the first cut specification for no much less than considered one of minimize size and minimize width.
Even extra preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.2 mm. In addition, or instead, the primary tobacco material is preferably shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally Fashion tobacco pipe, the primary tobacco material is shredded into strips from a sheet material having a thickness of lower than about 0.95 mm. Even more preferably, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about zero.eighty five mm.
A tobacco cut filler based on claim 1 or 2, whereby the primary tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses involved by the cigarette-making process. In explicit, there was concern that during the cigarette-making process the tobacco particle can be uncovered to high tensions and frictions which might cause particles prepared in accordance with the minimize specification no. 10 to break. This could have decreased the benefit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an apparatus for forming a tobacco reduce filler in accordance with the present invention. Figures depict a quantity of examples of significantly shapes into which tobacco material for forming a reduce filler in accordance with the current invention may be reduce.
