Because of the decreased tobacco fibre length throughout the reconstituted tobacco material, publicity to the identical therapies as tobacco lamina may degrade, to some extent, the reconstituted tobacco. By method of instance, during drying, the moisture content of reconstituted tobacco is greatly lowered, leading to shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the slicing methods generally employed to convert the tobacco material blend into filler could lead to some lamination and compression of the reconstituted tobacco material. All this causes a reduction in the filling power of the treated reconstituted tobacco and, accordingly, of the tobacco reduce filler as a whole. A mode of a discrete probability distribution, as is the case with the minimize length distribution among the reduce strips of the first tobacco material is a worth at which the likelihood mass operate takes a maximum value. Thus, in a unimodal distribution, the likelihood mass operate only has one most value, and that corresponds to the most likely worth of minimize size .
According to an aspect of the present invention, there is provided a tobacco minimize filler comprising a first tobacco material minimize in accordance with a first reduce specification, wherein the first cut specification units a minimum of predetermined first cut width and first cut size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for getting ready tobacco stem to be used as filler for a smoking article contains classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling each grade individually. Each grade is rolled under rolling conditions optimized for that grade including rolling the grade through the nip between rollers with the nip measurement being adjusted for each grade in order to realize a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted earlier than the rolling.
In addition, a second couple of blends was used, that contained 70 percent by weight of natural tobacco particles and 30 p.c by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of an individual reduce strip is taken at the point along the size of the strip that yields the biggest cross-sectional space. Further, the filling power of the shredded first tobacco material could be maximised by deciding on an acceptable first reduce specification. This leads to an improved filling energy of the minimize filler as a complete, significantly when the primary tobacco material is blended with at least another tobacco materials.
Even more preferably, first tobacco materials is shredded into strips having a reduce size of at least about 15 mm. In addition, or as an alternative, the primary tobacco materials is preferably shredded into strips having a minimize size of less than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a cut size of less than about 50 mm. Even extra preferably, the first tobacco materials is shredded into strips having a cut size of less than about 40 mm. In most popular embodiments, the first tobacco material is shredded into strips having a cut size from about 5 mm to about 60 mm. The term “sectional reduce width” is used in the present specification to describe the side- to-side width of 1 such portion of a cut strip of tobacco material.
Even more preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of no much less than about zero.2 mm. In addition, or in its place, the first tobacco material is ideally shredded into strips from a sheet material 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 zero.95 mm. Even more ideally, the first tobacco materials is shredded into strips from a sheet material having a thickness of less than about zero.85 mm.
Suitable pure tobacco leaf materials embody tobacco lamina, tobacco stem materials and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco materials could embody any kind of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco cut filler in accordance with the present invention includes a first tobacco material minimize in accordance with a first cut specification, wherein the primary minimize specification sets no less than predetermined first minimize width and first reduce size. The time period “filling power” is used to explain the volume of house taken up by a given weight or mass of a tobacco material. The greater the filling power of a tobacco materials, the decrease the burden of the fabric required to fill a tobacco rod of normal dimensions.
In practice, one such minimize strip may be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters comparable to the peak amplitude, peak-to-peak amplitude, interval of a sine wave may be used to explain the shape of one such reduce strips. A tobacco minimize filler contains a first tobacco materials reduce in accordance with a first cut specification, wherein the first reduce specification sets a minimal of predetermined first cut width and first minimize size. A tobacco cut filler according to any one of many preceding claims, whereby the primary tobacco material is shredded into strips having a minimize width from about zero.2 mm to about 1 mm.
Should one such particle break at a location in the central V-shaped portion, the 2 resulting components of the particles would nonetheless be successfully V-shaped. The highest CCV values were obtained for reduce specification no. three, which substantially corresponds to particles having a Y-shape. However, it was found that when particles had been produced from the same sheet of reconstituted tobacco according to cut specification no. three are produced, a big 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 three were measured. Tobacco reduce fillers based on the current invention could additionally be ready by a technique comprising offering a primary tobacco material and slicing the first tobacco material in accordance with a first cut specification setting at least predetermined first minimize width and first cut size. Tobacco reduce filler in accordance with the present invention may be included into a big selection of smoking articles.
A tobacco minimize filler according to any one of many previous claims, wherein the first tobacco materials is shredded into strips having a cut size from about 5 mm to about 60 mm. A tobacco minimize filler in accordance with any one of claims 2 to four, wherein the second tobacco material is a natural tobacco leaf material. An angle of ninety levels was thought of to be undesirable, in that it might lead basically to a form fairly much like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the strategy ideally comprises the step of blending the minimize first tobacco material and the reduce second tobacco materials.
The yield of flat rolled stem which may be used instantly as filler is increased, and the average stem length and thus the average length of cut filler from stem is elevated. A tobacco cut filler according to any one of many preceding claims having a filling power of no much less than 3.5 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. Accordingly, tobacco particles were prepared from the identical sheet of reconstituted tobacco in accordance with the minimize specification illustrated in Figure 12, wherein the cut width SCW1 is of zero.9 millimetres, the cut length CL1 is of 4.94 millimetres and the global width CW1 is of 12.50 millimetres.
