Conventionally, minimize 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 during a threshing process. Much of the stem portion that remains after the lamina has been removed and separated isn’t used. However, it’s not uncommon to add some tobacco stems back into the minimize filler together with the lamina.
Preferably, the first tobacco material is shredded into strips wherein the cut length is greater than the minimize width. Further, when reconstituted tobacco undergoes the identical treatments as tobacco lamina, a major quantity of tobacco mud is fashioned. Besides, within the curiosity of course of economic system, it’s fascinating that the tobacco dust be reprocessed in some form or different to extend the overall effectivity.
The yield of flat rolled stem which can be used directly as filler is elevated, and the common stem size and thus the average length of reduce filler from stem is elevated. A tobacco reduce filler according to any one of many preceding claims having a filling energy of at least 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. Accordingly, tobacco particles have been prepared from the identical sheet of reconstituted tobacco based on the cut specification illustrated in Figure 12, whereby the minimize width SCW1 is of 0.9 millimetres, the reduce size CL1 is of four.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
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 ideally, the first tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about zero.three mm, most preferably from a sheet materials having a thickness of about zero.2 mm. A tobacco reduce filler in accordance with any one of claims 1 to 9, wherein the primary Filling cut tobacco tobacco materials is shredded into strips each comprising a minimal of a primary strip structure comprising a branching node from which a further strip construction branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of reduce strips together with one or more V-shaped structure. Each V construction includes two considerably straight elements forming an angle.
Even extra ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of at least about zero.2 mm. In addition, or instead, the first tobacco material is preferably shredded into strips from a sheet material having a thickness of lower 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 zero.95 mm. Even extra preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about 0.85 mm.
Even extra preferably, first tobacco materials is shredded into strips having a cut size of a minimal of about 15 mm. In addition, or as an alternative, the primary tobacco material is preferably shredded into strips having a minimize size of less than about 60 mm. More ideally, the first tobacco materials is shredded into strips having a cut length of less than about 50 mm. Even extra ideally, the first tobacco materials is shredded into strips having a minimize length of less than about 40 mm. In most popular embodiments, the first tobacco material is shredded into strips having a reduce length from about 5 mm to about 60 mm. The term “sectional minimize width” is used within the current specification to explain the side- to-side width of 1 such portion of a cut strip of tobacco material.
Should one such particle break at a location in the central V-shaped portion, the 2 resulting components of the particles would nonetheless be effectively V-shaped. The highest CCV values were obtained for minimize specification no. three, which substantially corresponds to particles having a Y-shape. However, it was found that when particles had been produced from the same sheet of reconstituted tobacco in accordance with reduce specification no. three are produced, a major fraction of the tobacco material went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within the following Table three were measured. Tobacco cut fillers in accordance with the present invention could also be prepared by a way comprising offering a primary tobacco materials and cutting the primary tobacco materials in accordance with a primary minimize specification setting at least predetermined first cut width and first reduce size. Tobacco cut filler in accordance with the current invention could also be included into quite lots of smoking articles.
In apply, one such minimize strip may be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters comparable to the peak amplitude, peak-to-peak amplitude, period of a sine wave may be used to describe the shape of one such minimize strips. A tobacco reduce filler contains a primary tobacco materials minimize in accordance with a primary Fashion tobacco pipe minimize specification, whereby the first reduce specification sets a minimum of predetermined first reduce width and first cut length. A tobacco cut filler according to any one of many previous claims, wherein the first tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm.
