Alternative methods for the manufacture of reconstituted tobacco sheets are additionally recognized to the skilled individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to check with a web, preferably with substantially uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp shaped from tobacco particles by one of several methods known within the artwork. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced through the manufacturing process.
The expressions “last minimize width” and “ultimate minimize size” are used herein to explain the minimize width and cut size of a tobacco materials as found in a tobacco cut filler utilized in a tobacco product. The method may additional comprise a step of conditioning the primary tobacco materials previous to chopping the primary tobacco materials. Further, the strategy might comprise a step of controlling the moisture content material of the minimize filler by adjusting the moisture content of the first tobacco material.
A tobacco minimize filler according to claim 1 or 2, whereby the first tobacco material is a pre- processed tobacco material. In a 3rd experiment, the reduce specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In specific, there was concern that in the course of the cigarette-making course of the tobacco particle can be uncovered to high tensions and frictions which might trigger particles prepared in accordance with the reduce specification no. 10 to break. This may have decreased the benefit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco minimize filler in accordance with the present invention. Figures depict a quantity of examples of significantly shapes into which tobacco material for forming a cut filler in accordance with the current invention could additionally be cut.
Reconstituted tobacco is fashioned from tobacco materials similar to tobacco stems, tobacco stalks, leaf scraps and tobacco dust, which are produced in the course of the manufacturing processes of tobacco products. Such tobacco materials may, for example, be floor to a fine powder and then mixed with water and usually with a binder, corresponding to guar gum, to type a slurry. This slurry is then solid onto a supportive floor, similar to a belt conveyor, and dried to kind a sheet (so known as ‘forged leaf) that can be removed from the supportive surface and wound into bobbins.
Without wishing to be sure to concept, it is going to be appreciated that during any slicing, rolling or extruding operation, the tobacco fibres typically align in a given path, which can thus be recognized because the longitudinal course of the tobacco material. The “minimize length” of a cut strip of tobacco material for incorporation in minimize fillers based on the present invention may therefore be measured along the principle path of fibre alignment, which usually corresponds to the longitudinal course. Thus, the minimize size of a person reduce strip can be precisely measured using a standard measuring device underneath a microscope. In a traditional course of, reconstituted tobacco or tobacco stem materials or each are sometimes blended with threshed tobacco lamina to endure a series of remedies, such as conditioning and drying. To this objective, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like items having a non-uniform dimension, typically of a number of square centimetres.
In addition, a second couple of blends was used, that contained 70 p.c by weight of natural 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 an individual minimize strip is taken on the level alongside the length of the strip that yields the most important cross-sectional area. Further, the filling energy Fashion tobacco pipe of the shredded first tobacco materials could be maximised by choosing an acceptable first minimize specification. This results in an improved filling power of the cut filler as a whole, significantly when the primary tobacco material is mixed with a minimal of another tobacco material.
Suitable pure tobacco leaf supplies embody tobacco lamina, tobacco stem material and tobacco stalk materials. The pure tobacco leaf materials used because the second tobacco materials might embrace any sort of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco cut filler in accordance with the current invention comprises a first tobacco materials cut in accordance with a primary cut specification, wherein the primary minimize specification sets no much less than predetermined first cut width and first cut length. The time period “filling power” is used to explain the quantity of house taken up by a given weight or mass of a tobacco materials. The greater the filling power of a tobacco materials, the lower the weight of the fabric required to fill a tobacco rod of normal dimensions.
Experiments were carried out to be able to assess the influence of different shapes and minimize specifications to key parameters of tobacco minimize filler particles, such as the filling energy. In extra element, Figure 1 reveals a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- formed, it is attainable to measure a wave length of the reduce strip, which considerably corresponds to the strip reduce size divided by the variety of repetitions of the zigzag or wave. For occasion tobacco pipe, in the reduce strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, more ideally from about 2 mm to about 12 mm, even more preferably from four mm to 10 mm. Preferably, the tobacco minimize filler further comprises a second tobacco material reduce in accordance with a second cut specification differing from the first reduce specification for a minimum of one of cut size and reduce width.
