Without wishing to be certain to concept, it is going to be appreciated that in any cutting, rolling or extruding operation, the tobacco fibres typically align in a given course, which may thus be identified because the longitudinal direction of the tobacco materials. The “minimize length” of a cut strip of tobacco materials for incorporation in cut fillers according to the present invention could due to this fact be measured alongside the main direction of fibre alignment, which typically corresponds to the longitudinal course. Thus, the minimize length of a person reduce strip may be precisely measured utilizing a standard measuring system under a microscope. In a conventional process, reconstituted tobacco or tobacco stem materials or each are typically blended with threshed tobacco lamina to undergo a sequence of treatments, such as conditioning and drying. To this purpose, a reconstituted tobacco sheet is usually ripped into randomly formed sheet-like pieces having a non-uniform size, typically of several square centimetres.
More preferably, the primary tobacco material is shredded into strips having a cut width of less than about 0.ninety five mm. Even more preferably, the primary tobacco material is shredded into strips having a cut width of less than about zero.9 mm. In preferred embodiments, the first tobacco materials is shredded into strips having a reduce width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
By way of example, tobacco stems may be floor to a nice powder and then mixed with tobacco mud, guar gum, and water to type an aqueous slurry. This aqueous slurry may be forged and dried to type a reconstituted tobacco sheet. As another, suitable tobacco supplies could additionally be combined in an agitated tank with water to acquire tobacco pipe a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the net. Figure thirteen illustrates an equipment 30 for the manufacture of a tobacco reduce filler in accordance with the present invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding device 36.
More preferably, the first tobacco material is shredded into strips having a reduce width of a minimal of about zero.25 mm. Even more preferably, the primary tobacco material is shredded into strips having a cut width of a minimal of about 0.3 mm. In addition, or in its place, the first tobacco materials is preferably shredded into strips having a reduce width of lower than about 1 mm.
Even extra ideally, first tobacco material is shredded into strips having a reduce size of a minimal of about 15 mm. In addition, or in its place, the primary tobacco material is ideally shredded into strips having a cut length of less than about 60 mm. More ideally, the first tobacco material is shredded into strips having a cut length of lower than about 50 mm. Even more ideally, the first Fashion tobacco pipe tobacco material is shredded into strips having a reduce length of lower than about forty mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. The term “sectional minimize width” is used within the present specification to explain the side- to-side width of 1 such portion of a minimize strip of tobacco material.
Alternative strategies for the manufacture of reconstituted tobacco sheets are also identified to the expert particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to check with an online, preferably with considerably uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp formed from tobacco particles by certainly one of a quantity of methods identified in the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced through the manufacturing course of.
Further, the second Y-shaped construction includes a second branching node from which a rectangular construction branches off. In the embodiment of Figure 1 1 , the cut strip comprises a primary Y-shaped structure including a primary branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure comprises a second branching node from which a third Y-shaped structure branches off.
In preferred embodiments, the first tobacco material is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even extra preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness from about zero.1 mm to about zero.three mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco minimize filler in accordance with any one of claims 1 to 9, wherein the first tobacco materials is shredded into strips each comprising a minimum of a first strip construction comprising a branching node from which an extra strip structure branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of cut strips together with one or more V-shaped construction. Each V structure comprises two considerably straight elements forming an angle.
Experiments have been carried out to find a way to assess the impression of different shapes and cut specs to key parameters of tobacco reduce filler particles, such as the filling power. In more detail, Figure 1 exhibits a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- formed, it’s attainable to measure a wave size of the reduce strip, which substantially corresponds to the strip cut length divided by the variety of repetitions of the zigzag or wave. For instance, in the minimize strip of Figure 1 the zigzag is repeated 10 occasions. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, more preferably from about 2 mm to about 12 mm, much more ideally from 4 mm to 10 mm. Preferably, the tobacco minimize filler further includes a second tobacco material reduce in accordance with a second cut specification differing from the primary cut specification for at least one of cut length and cut width.
