Suitable pure tobacco leaf materials include tobacco lamina, tobacco stem materials and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco materials might embody any type of tobacco leaf, including for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco reduce filler in accordance with the present invention includes a primary tobacco material minimize in accordance with a first cut specification, whereby the primary cut specification units at least predetermined first minimize width and first cut length. The time period “filling power” is used to explain the quantity of house taken up by a given weight or mass of a tobacco material. The greater the filling energy of a tobacco materials, the decrease the burden of the material required to fill a tobacco rod of standard dimensions.
Blending the cut first tobacco materials and the cut second tobacco materials. All ISO publications and supplies are protected by copyright and are subject to the user’s acceptance of ISO’s situations of copyright. After some 8-10 weeks, the seedlings are planted in the fields the place they develop for roughly two months.
Conventionally, reduce filler tobacco products for smoking articles are shaped 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 remains after the lamina has been removed and separated isn’t used. However, it is not uncommon to add some tobacco stems back into the cut filler together with the lamina.
By way of example, tobacco stems could also be floor to a fine powder and then blended with tobacco mud, guar gum, and water to kind an aqueous slurry. This aqueous slurry may be cast and dried to form a reconstituted tobacco sheet. As an alternate, appropriate tobacco supplies could also be blended in an agitated tank with water to acquire a pulp. This web is fed onwards to a press, the place the surplus water is squeezed out of the net. Figure 13 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.
More preferably, the first tobacco material is shredded into strips having a cut width of lower than about zero.95 mm. Even extra ideally, the primary tobacco materials is shredded into strips having a cut width of less than about 0.9 mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf material.
For example, a bimodal distribution may correspond successfully to 2 teams of reduce strips having totally different average minimize lengths , one group being larger than the other. Preferably, the first tobacco materials is shredded into strips from a sheet material tobacco pipe having a thickness of a minimal of about zero.05 mm. More preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of no much less than about 0.1 mm.
Preferably, the first tobacco materials is shredded into strips wherein the cut length is greater than the minimize width. Further, when reconstituted tobacco undergoes the identical therapies as tobacco lamina, a major quantity of tobacco mud Filling cut tobacco is formed. Besides, within the interest of process financial system, it’s fascinating that the tobacco dust be reprocessed in some kind or other to increase the general efficiency.
More preferably, the primary tobacco material is shredded into strips having a cut width of at least about 0.25 mm. Even more ideally, the primary tobacco materials is shredded into strips having a cut width of no less than about zero.three mm. In addition, or in its place, the first tobacco material is ideally shredded into strips having a reduce width of less than about 1 mm.
