Even more ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness of no less than about zero.2 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet materials having a thickness of lower than about 0.95 mm. Even extra preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of less than about 0.85 mm.
The yield of flat rolled stem which can be used directly as filler is elevated, and the typical stem length and thus the average size of reduce filler from stem is increased. A tobacco minimize filler according to any one of many preceding claims having a filling power of a minimum of three.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco according to the minimize specification illustrated in Figure 12, wherein the minimize width SCW1 is of zero.9 millimetres, the minimize size CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
Within a minimize strip of tobacco materials, the sectional reduce width will be the substantially identical for all the strip parts. While this can be preferable, the sectional reduce width may also range from one strip portion to a different. Typically, prior to being cut, a tobacco materials may bear different mechanical operations, corresponding to rolling or extrusion.
By method of instance, tobacco stems could also be floor to a fantastic powder and then blended with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could also be cast and dried to kind a reconstituted tobacco sheet. As an alternate, suitable tobacco supplies may be mixed in an agitated tank with water to acquire a pulp. This net is fed onwards to a press, where the excess water is squeezed out of the web. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the current invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
Even more preferably, first tobacco materials is shredded into strips having a cut length of a minimal of about 15 mm. In addition, or as an alternative, the first tobacco materials is preferably shredded into strips having a reduce size of lower than about 60 mm. More preferably, the first tobacco materials is shredded into strips having a reduce length of lower than about 50 mm. Even extra preferably, the first tobacco pipe tobacco material is shredded into strips having a cut size of less than about 40 mm. In preferred embodiments, the first tobacco materials is shredded into strips having a minimize length from about 5 mm to about 60 mm. The term “sectional reduce width” is used in the current specification to explain the side- to-side width of one such portion of a minimize strip of tobacco materials.
Further, the second Y-shaped construction contains a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the minimize strip includes a primary Y-shaped structure including a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction comprises a second branching node from which a 3rd Y-shaped structure branches off.
More ideally, the primary tobacco materials is shredded into strips having a reduce width of lower than about zero.ninety five mm. Even extra ideally, the first tobacco materials is shredded into strips having a minimize width of lower Fashion tobacco pipe than about 0.9 mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a minimize width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf material.
Conventionally, cut filler tobacco products for smoking articles are fashioned predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf during a threshing process. Much of the stem portion that remains after the lamina has been removed and separated just isn’t used. However, it’s not unusual to add some tobacco stems back into the reduce filler along with the lamina.
