By way of example, tobacco stems may be floor to a fantastic powder and then combined with tobacco dust, guar gum, and water to type an aqueous slurry. This aqueous slurry could also be solid and dried to kind a reconstituted tobacco sheet. As an alternate, suitable tobacco supplies may be blended in an agitated tank with water to obtain a pulp. This internet is fed onwards to a press, the place the excess water is squeezed out of the online. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco cut filler in accordance with the present invention. A internet 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding system 36.
The yield of flat rolled stem which may be used directly as filler is elevated, and the common stem size and thus the average size of minimize filler from stem is elevated. A tobacco reduce filler according to any one of many previous claims having a filling energy of no much less than three.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles had been prepared from the same sheet of reconstituted tobacco based on the cut specification illustrated in Figure 12, whereby the cut width SCW1 is of zero.9 millimetres, the reduce size CL1 is of four.ninety four millimetres and the global width CW1 is of 12.50 millimetres.
For instance, a bimodal distribution could correspond successfully to 2 teams of cut strips having totally different common reduce lengths , one group being bigger than the opposite. Preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of at least about zero.05 mm. More preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about 0.1 mm.
The thickness subsequently corresponds substantially to the thickness of the tobacco materials fed to the cutting or shredding apparatus. The thickness of an individual cut strip may be measured using a standard measuring device underneath a microscope. In some embodiments, the thickness of a tobacco material forming the reduce strip may be considerably fixed. In other embodiments, the thickness of the tobacco materials forming the reduce strip may differ alongside the longitudinal course, alongside a path perpendicular to the longitudinal course, or along both. The thickness of an individual reduce strip is measured at the level alongside the longitudinal direction of cutting that yields the biggest cross-sectional area.
Blending the reduce first tobacco material and the reduce second tobacco materials.

After some 8-10 weeks, the seedlings are planted within the fields where they develop for about two months.
This document specifies a method for dedication of filling power for preparation of fine-cut tobacco smoking articles. Its leaves are 20 – 50 cm lengthy and vary in colour from light brown to very dark brown. When the lowest leaves are harvested, the whole plant can both be reduce down and dried or the plant can be harvested leaf-by-leaf. A method in accordance with any one of claims 15 to 18, additional comprising conditioning the primary tobacco materials prior to cutting the primary tobacco material. A technique based on claim 18, comprising controlling the moisture content of the cut filler by adjusting the moisture content material of the first tobacco materials. A tobacco minimize filler based on declare 1 , further comprising a second tobacco material minimize in accordance with a second minimize specification differing from the primary reduce specification for at least considered one of minimize size and cut width.
Should one such particle break at a location within the central V-shaped portion, the 2 resulting elements of the particles would nonetheless be effectively V-shaped. The highest CCV values had been obtained for cut specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was found that when particles have been produced from the same sheet of reconstituted tobacco in accordance with cut specification no. three are produced, a major 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 have been measured. Tobacco reduce fillers according to the present invention could also be prepared by a way comprising providing a primary tobacco material and cutting the primary tobacco material in accordance with a primary reduce specification setting no less than predetermined first cut width and first cut size. Tobacco cut filler in accordance with the present invention could also be integrated into a wide range of smoking articles.
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 first tobacco material is preferably shredded into strips having a minimize length of lower than about 60 mm. More preferably, the first tobacco materials is shredded into strips having a cut length of lower than about 50 mm. Even more preferably, the first tobacco materials is shredded into strips having a minimize length of lower than about 40 mm. In most well-liked embodiments, the primary tobacco material is shredded into strips having a minimize length from about 5 mm to about 60 mm. The time period “sectional reduce width” is used within the present specification to describe the side- to-side width of one such portion of a cut strip of tobacco material.
Suitable natural tobacco leaf materials include tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf materials used as the second tobacco materials could embrace any kind of tobacco leaf, together with for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco cut filler based on the current invention contains a first tobacco materials cut in accordance with a primary reduce specification, wherein the first minimize specification sets no much less than predetermined first cut width and first minimize length. The term “filling power” is used to explain the quantity of space taken up by a given weight or mass of a tobacco materials. The higher the filling energy of a tobacco material, the lower the load of the fabric required to fill a tobacco rod of normal dimensions.
Because of the lowered tobacco fibre size within the reconstituted tobacco material, exposure to the same therapies as tobacco lamina may degrade, to some extent, the reconstituted tobacco. By way of instance, throughout drying, the moisture content of reconstituted tobacco is greatly decreased, resulting in shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the slicing methods generally employed to transform the tobacco materials mix into filler might lead to some lamination and compression of the reconstituted tobacco material Filling cut tobacco. All this causes a reduction within the filling power of the treated reconstituted tobacco and, accordingly, of the tobacco cut filler as a whole. A mode of a discrete probability distribution, as is the case with the minimize length distribution among the minimize strips of the first tobacco materials is a worth at which the chance mass function takes a maximum worth. Thus, in a unimodal distribution, the likelihood mass function solely has one most worth, and that corresponds to the more than likely value of reduce length .
