For example, a bimodal distribution may correspond successfully to 2 teams of reduce strips having totally different average reduce lengths , one group being larger than the other. Preferably, the first tobacco materials is shredded into strips from a sheet material Fashion tobacco pipe having a thickness of at least about 0.05 mm. More ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of at least about 0.1 mm.
More ideally, the first tobacco material is shredded into strips having a cut width of no much less than about 0.25 mm. Even extra ideally, the primary tobacco material is shredded into strips having a reduce tobacco pipe width of a minimum of about zero.three mm. In addition, or as an alternative, the primary tobacco materials is ideally shredded into strips having a minimize width of less than about 1 mm.
Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of a minimum of about zero.2 mm. In addition, or in its place, the first tobacco material is preferably shredded into strips from a sheet materials having a thickness of less than about 1 mm. More preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of less than about zero.ninety five mm. Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about zero.85 mm.
A tobacco reduce filler according to any one of many previous claims, wherein the primary tobacco material is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco minimize filler according to any one of claims 2 to 4, whereby the second tobacco materials is a pure tobacco leaf material. An angle of 90 degrees was considered to be undesirable, in that it might lead basically to a shape fairly just like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” components. Further, the method preferably contains the step of mixing the cut first tobacco materials and the reduce second tobacco material.
Alternative methods for the manufacture of reconstituted tobacco sheets are also identified to the skilled person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to a web, preferably with considerably uniform thickness, which might be produced by the rolling or casting of an aqueous slurry or pulp shaped from tobacco particles by considered one of a quantity of strategies identified in the artwork. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced during the manufacturing course of.
The minimize width of one such Y-shaped strip corresponds substantially to the gap between the ends of the second and third strip portions as measured alongside a direction perpendicular to the course defined by an axis of the first strip portion. Within the identical Y-shaped strip, the sectional cut width of each strip portion may as a substitute Filling cut tobacco be measured alongside a course considerably perpendicular to the axis of each strip portion. In some cases, similar to where the cut strip of tobacco material is considerably rectangular , the sectional cut width and the strip cut width are the identical.
In addition, the formation of tobacco mud is decreased in contrast with conventional manufacturing methods. Accordingly, the need to acquire and re-process tobacco dust is considerably decreased and the overall effectivity of the manufacturing process is thus advantageously increased. A tobacco reduce filler in accordance with any one of many previous claims, whereby the primary tobacco material is shredded into strips having a sinusoidal shape, wherein a wave size of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco minimize filler in accordance with any one of many preceding claims, wherein the first tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.05 mm to about 1 mm. Table 2 under lists the values of CCV measured at a reference moisture worth of 12.5 p.c oven volatiles for each pattern.
By way of example, tobacco stems may be ground to a fine powder after which blended with tobacco mud, guar gum, and water to type an aqueous slurry. This aqueous slurry may be cast and dried to kind a reconstituted tobacco sheet. As an alternative, suitable tobacco supplies may be blended in an agitated tank with water to obtain a pulp. This internet is fed onwards to a press, where the excess water is squeezed out of the online. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco minimize 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.
Should one such particle break at a location within the central V-shaped portion, the 2 ensuing components of the particles would still be effectively V-shaped. The highest CCV values had been obtained for minimize specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles had been produced from the identical sheet of reconstituted tobacco according to cut specification no. three are produced, a major fraction of the tobacco material 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 were measured. Tobacco cut fillers based on the current invention may be ready by a way comprising offering a primary tobacco material and slicing the first tobacco material in accordance with a primary cut specification setting no much less than predetermined first cut width and first minimize size. Tobacco minimize filler in accordance with the present invention could also be incorporated into quite a lot of smoking articles.
