In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the cut width of a person cut strip is taken on the level along the size of the strip that yields the biggest cross-sectional space. Further, the filling energy of the shredded first tobacco materials could be maximised by selecting an acceptable first cut specification. This results in an improved filling power of the cut filler as an entire, significantly when the first tobacco materials is mixed with at least one other tobacco material.
A tobacco cut filler based on declare 1 or 2, wherein the first tobacco materials is a pre- processed tobacco material. In a third experiment, the minimize specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses involved by the cigarette-making course of. In particular, there was concern that during the cigarette-making process the tobacco particle would be uncovered to high tensions and frictions which might trigger particles prepared in accordance with the cut specification no. 10 to interrupt. This might have lowered the profit 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 current invention. Figures depict a number of examples of notably shapes into which tobacco material for forming a minimize filler in accordance with the present invention could additionally be reduce.
By method of instance, tobacco stems may be ground to a nice powder and then mixed with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry may be cast and dried to kind a reconstituted tobacco sheet. As an alternate, suitable tobacco supplies could additionally be combined in an agitated tank with water to acquire Filling cut tobacco a pulp. This web is fed onwards to a press, where the surplus water is squeezed out of the net. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the current invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding system 36.
More preferably, the primary tobacco material is shredded into strips having a reduce width of less than about zero.ninety five mm. Even more ideally, the first tobacco material is shredded into strips having a minimize width of lower than about zero.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a natural tobacco leaf material.
A tobacco reduce filler based on any one of the preceding claims, wherein the first tobacco material is shredded into strips having a reduce length from about 5 mm to about 60 mm. A tobacco minimize filler based on any certainly one of claims 2 to 4, wherein the second tobacco material is a natural tobacco leaf material. An angle of 90 degrees was thought of to be undesirable, in that it will lead primarily to a form fairly much like the shape of Figure 6, and so an angle of 60 degrees was chosen for the “V” elements. Further, the method preferably contains the step of blending the minimize first tobacco materials and the reduce second tobacco material.
According to an aspect of the current invention, there may be provided a tobacco minimize filler comprising a first tobacco material minimize in accordance with a first minimize specification, whereby the primary reduce specification units no less than predetermined first reduce width and first reduce length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for getting ready tobacco stem for tobacco pipe use as filler for a smoking article consists of classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling each grade separately. Each grade is rolled beneath rolling conditions optimized for that grade including rolling the grade via the nip between rollers with the nip size being adjusted for every grade so as to achieve a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted earlier than the rolling.
Because of the reduced tobacco fibre length within the reconstituted tobacco material, publicity to the same therapies as tobacco lamina may degrade, to some extent, the reconstituted tobacco. By way of example, during drying, the moisture content material of reconstituted tobacco is tremendously lowered, leading to shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the slicing methods typically employed to convert the tobacco materials blend into filler might lead to some lamination and compression of the reconstituted tobacco material. All this causes a discount in the filling energy of the treated reconstituted tobacco and, accordingly, of the tobacco minimize filler as an entire. A mode of a discrete probability distribution, as is the case with the minimize length distribution among the many reduce strips of the first tobacco material is a price at which the likelihood mass function takes a maximum worth. Thus, in a unimodal distribution, the likelihood mass function only has one most value, and that corresponds to the more than likely value of minimize size .
As the name implies, it is simply a combine of completely different tobacco sorts, cuts and flavors. They are straightforward to fill and smoke, and have greater robustness and taste variety than unfastened Fashion tobacco pipe cut tobacco on its own. The first tobacco material could also be cut into strips having any appropriate form, together with rectangular, trapezoidal, sinusoidal, Y-shaped, X-shaped and V-shaped.
Should one such particle break at a location in the central V-shaped portion, the 2 resulting elements of the particles would nonetheless be successfully V-shaped. The highest CCV values have been obtained for cut specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco according to minimize specification no. 3 are produced, a significant fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within the following Table 3 have been measured. Tobacco reduce fillers in accordance with the current invention could also be prepared by a method comprising providing a primary tobacco materials and slicing the first tobacco materials in accordance with a first minimize specification setting no much less than predetermined first cut width and first minimize size. Tobacco cut filler in accordance with the present invention could additionally be included into a big selection of smoking articles.
In addition, the formation of tobacco dust is decreased compared with traditional manufacturing methods. Accordingly, the need to gather and re-process tobacco dust is significantly decreased and the general efficiency of the manufacturing process is thus advantageously elevated. A tobacco cut filler based on any one of the previous claims, wherein the first tobacco material is shredded into strips having a sinusoidal form, whereby a wave length of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco minimize filler based on any one of the preceding claims, wherein the first tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Table 2 below lists the values of CCV measured at a reference moisture value of 12.5 percent oven volatiles for each sample.
