Further, the second Y-shaped construction includes a second branching node from which a rectangular structure branches off. In the embodiment of Figure 1 1 , the minimize strip comprises a primary Y-shaped construction including a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction includes a second branching node from which a 3rd Y-shaped construction branches off.
The shredding system is configured to chop the reconstituted tobacco in accordance to a primary reduce specification, whereby both reduce width and cut size are predetermined. The minimize strips are dropped onto a conveyor belt 38 organized beneath the shredding system 36 and defining a collection surface upon which the cut strips fall out of the shredding device. Additional means T could additionally be offered for tensioning the web of reconstituted tobacco as it Filling cut tobacco is unwound off the bobbin. Further, the apparatus 30 may comprise sensors 40 for detecting the moisture content material of the online of reconstituted tobacco upstream of the shredding system 36. In addition, the apparatus 30 may comprise mass move controllers forty two, forty four tailored to adjust the speed at which the online of reconstituted tobacco is fed to the shredding gadget 36 and the speed of the conveyor belt 38.
By way of example, tobacco stems may be ground to a fine powder after which mixed with tobacco mud, guar gum, and water to type an aqueous slurry. This aqueous slurry could additionally be solid and dried to form a reconstituted tobacco sheet. As an alternative, appropriate tobacco materials may be mixed in an agitated tank with water to obtain a pulp. This internet is fed onwards to a press, the place the surplus water is squeezed out of the online. Figure 13 illustrates an apparatus 30 for the manufacture of a tobacco minimize filler in accordance with the present invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
Even extra preferably, first tobacco materials is shredded into strips having a cut length of a minimal of about 15 mm. In addition, or in its place, the first tobacco material is ideally shredded into strips having a reduce length of less than about 60 mm. More preferably, the first tobacco materials is shredded into strips having a minimize size of less than about 50 mm. Even extra preferably, the first tobacco materials is shredded into strips having a cut size of lower than about 40 mm. In most popular embodiments, the primary tobacco material is shredded into strips having a minimize length from about 5 mm to about 60 mm. The term “sectional cut width” is used within the present specification to explain the side- to-side width of one such portion of a minimize strip of tobacco material.
Should one such particle break at a location within the central V-shaped portion, the 2 resulting elements of the particles would still be successfully V-shaped. The highest CCV values had been obtained for cut specification no. three, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the identical 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 in the Fashion tobacco pipe following Table 3 had been measured. Tobacco reduce fillers in accordance with the present invention may be ready by a way comprising providing a first tobacco material and chopping the primary tobacco material in accordance with a primary minimize specification setting at least predetermined first cut width and first cut size. Tobacco minimize filler in accordance with the current invention may be included into a wide selection of smoking articles.
More ideally, the first tobacco material is shredded into strips having a reduce width of a minimal of about zero.25 mm. Even more ideally, the primary tobacco material is shredded into strips having a cut width of a minimum of about 0.three mm. In addition, or in its place, the primary tobacco material is preferably shredded into strips having a cut width of less than about 1 mm.
Suitable natural tobacco leaf supplies embody tobacco lamina, tobacco stem materials and tobacco stalk material. The natural tobacco leaf material used because the second tobacco materials may embrace 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 according to the current invention contains a primary tobacco material minimize in accordance with a primary tobacco pipe reduce specification, whereby the first minimize specification units no less than predetermined first reduce width and first minimize size. The time period “filling power” is used to describe the amount of space taken up by a given weight or mass of a tobacco material. The larger the filling energy of a tobacco material, the lower the weight of the material required to fill a tobacco rod of ordinary dimensions.
