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 throughout a threshing course of. Much of the stem portion that continues tobacco pipe to be after the lamina has been removed and separated isn’t used. However, it isn’t uncommon to add some tobacco stems back into the minimize filler along with the lamina.
More preferably, the first tobacco materials is shredded into strips having a minimize width of no less than about 0.25 mm. Even extra ideally, the primary tobacco material is shredded into strips having a cut width of no much less than about 0.3 mm. In addition, or in its place, the first tobacco material is preferably shredded into strips having a minimize width of less than about 1 mm.
For example, a bimodal distribution might correspond successfully to 2 groups of cut strips having completely different average minimize lengths , one group being bigger than the opposite. Preferably, the primary tobacco materials is shredded into strips from a sheet materials Fashion tobacco pipe having a thickness of at least about 0.05 mm. More preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of a minimum of about zero.1 mm.
By way of example, tobacco stems may be ground to a fine powder and then mixed with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could also be forged and dried to kind a reconstituted tobacco sheet. As another, appropriate tobacco materials could also be combined in an agitated tank with water to obtain a pulp. This net is fed onwards to a press, where the surplus water is squeezed out of the net. Figure 13 illustrates an apparatus 30 for the manufacture of a tobacco reduce 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 gadget 36.
The shredding system is configured to cut the reconstituted tobacco in accordance to a primary cut specification, whereby both minimize width and cut size are predetermined. The cut strips are dropped onto a conveyor belt 38 organized beneath the shredding system 36 and defining a group floor upon which the cut strips fall out of the shredding gadget. Additional means T may be provided for tensioning the web of reconstituted tobacco as it’s Filling cut tobacco unwound off the bobbin. Further, the apparatus 30 might comprise sensors 40 for detecting the moisture content material of the web of reconstituted tobacco upstream of the shredding gadget 36. In addition, the equipment 30 could comprise mass flow controllers 42, 44 tailored to regulate the pace at which the online of reconstituted tobacco is fed to the shredding device 36 and the velocity of the conveyor belt 38.
