According to a side of the present invention, there’s provided a tobacco minimize filler comprising a first tobacco materials minimize in accordance with a first reduce specification, whereby the first reduce specification units a minimal of predetermined first cut width and first cut size. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for getting ready tobacco stem to be used as filler for a smoking article includes classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling each grade separately. Each grade is rolled under rolling situations optimized for that grade together with rolling the grade through the nip between rollers with the nip size being adjusted for every grade in order to achieve a uniform rolled stem thickness and the oven volatiles content material of the stem being adjusted earlier than the rolling.
Even more ideally, first tobacco materials is shredded into strips having a reduce size of a minimum of about 15 mm. In addition, or instead, the primary tobacco materials is preferably shredded into strips having a cut size of lower than about 60 mm. More preferably, the primary tobacco material is shredded into strips having a minimize length of lower than about 50 mm. Even extra preferably, the first Filling cut tobacco tobacco material is shredded into strips having a cut size of lower than about forty mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. The term “sectional cut width” is used in the current specification to explain the side- to-side width of 1 such portion of a reduce strip of tobacco material.
By means of instance, tobacco stems may be floor to a fantastic powder and then combined with tobacco mud, guar gum, and water to kind an aqueous slurry. This aqueous slurry could additionally be cast and dried to type a reconstituted tobacco sheet. As an alternative, appropriate tobacco materials could additionally be mixed in an agitated tank with water to obtain a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the online. Figure thirteen illustrates an equipment 30 for the manufacture of a tobacco cut filler in accordance with the current invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding system 36.
In some embodiment, the reduce width distribution among the many cut strips of the first tobacco materials is preferably unimodal. In other embodiments, the minimize width distribution among the reduce strips of the first tobacco material could also be multimodal, together with specifically bimodal and trimodal. If a distribution has two or more modes, it’s usually known as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the first tobacco material is shredded into strips having a reduce width of no less than about 0.2 mm.
In turn, the third Y-shaped structure comprises a third branching node from which a rectangular construction branches off. In the embodiments of both Figures 9 and 1 1 the sectional cut width within all the buildings forming the reduce strips is substantially constant. By method of example, in a Y-shaped strip it is possible to identify a first strip portion extending alongside a first path and a second and third strip parts extending from the first strip parts alongside diverging directions, in order that they kind an angle.
Further, the second Y-shaped structure contains 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 together with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure contains a second branching node from which a 3rd Y-shaped structure branches off.
Conventionally, minimize filler tobacco merchandise 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 process. Much of the stem portion that remains after the lamina has been eliminated and separated just isn’t used. However, it isn’t uncommon to add some tobacco stems again into the cut filler together with the lamina.
In practice, one such minimize strip may be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters similar to the peak amplitude, peak-to-peak amplitude, interval of a sine wave may be used to describe the form of 1 such reduce strips. A tobacco minimize filler contains a first tobacco material minimize in accordance with a primary reduce specification, whereby the first reduce specification sets no less than predetermined first cut width and first reduce size. A tobacco minimize filler according to any one of the preceding claims, whereby the primary tobacco material is shredded into strips having a reduce width from about zero.2 mm to about 1 mm.
In addition, the formation of tobacco mud is lowered compared with conventional manufacturing methods. Accordingly, the need to gather and re-process tobacco dust is significantly lowered and the overall effectivity of the manufacturing process is thus advantageously increased. A tobacco reduce filler according to any one of many previous claims, whereby the first tobacco materials is shredded into strips having a sinusoidal shape, wherein a wave length of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco minimize filler according to any one of many preceding claims, whereby the primary tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Table 2 beneath lists the values of CCV measured at a reference moisture worth of 12.5 % oven volatiles for every sample.
Even extra preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness of a minimal of about zero.2 mm. In addition, or in its place, the first tobacco material is preferably shredded into strips from a sheet materials having a thickness of less than about 1 mm. More preferably , the first tobacco material is shredded into strips from a sheet materials having a thickness of less than about zero.95 mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of lower than about zero.85 mm.
