Further, the second Y-shaped construction includes a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the minimize strip includes a first Y-shaped construction including a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped construction comprises a second branching node from which a 3rd Y-shaped structure branches off.
In some embodiments, tobacco cut filler according to the invention could also be used within the tobacco rod of a combustible smoking article, such as a filter cigarette, cigarillo or cigar. Alternatively, the cut filler may be used to provide the tobacco aerosol generating substrate in a distillation based smoking article, or an electrically heated smoking system. Alternatively, the minimize filler could additionally be used as a roll-your-own or make-your-own product, or loose tobacco product to be used in a pipe.
More ideally, the primary tobacco material is shredded into strips having a cut width of less than about zero.95 mm. Even more ideally, the first tobacco material is shredded into strips having a cut width of lower than about zero.9 mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
A tobacco reduce filler based on declare 1 or 2, wherein the primary tobacco materials is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was barely modified with a view to improving the resistance of the particles to the stresses involved by the cigarette-making course of. In specific, there was concern that in the course of the cigarette-making course of the tobacco particle would be exposed to excessive tensions and frictions which might trigger particles prepared in accordance with the minimize specification no. 10 to break. This could have decreased the profit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an apparatus for forming a tobacco cut filler in accordance with the current invention. Figures depict a quantity of examples of notably shapes into which tobacco material for forming a minimize filler in accordance with the current invention could additionally be cut.
A tobacco cut filler according to any one of many previous claims, whereby the first tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco cut filler in accordance with any certainly one of claims 2 to 4, wherein the second tobacco materials is a pure tobacco leaf material. An angle of 90 degrees tobacco pipe was thought-about to be undesirable, in that it will lead basically to a form quite just like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” components. Further, the method preferably includes the step of mixing the cut first tobacco material and the reduce second tobacco materials.
Alternative strategies for the manufacture of reconstituted tobacco sheets are additionally recognized to the skilled individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with an online, ideally with substantially uniform thickness, that may be produced by the rolling or casting of an aqueous slurry or pulp shaped from tobacco particles by one of several methods known in the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced in the course of the manufacturing course of.
In addition, the formation of tobacco dust is reduced compared with conventional manufacturing methods. Accordingly, the necessity to gather and re-process tobacco mud is significantly reduced and the general effectivity of the manufacturing course of is thus advantageously increased. A tobacco reduce filler in accordance with any one of the preceding claims, whereby the first tobacco materials is shredded into strips having a sinusoidal form, whereby a wave length of the sinusoidal form is from about 1 mm to about 15 mm. A tobacco cut filler according to any one of the preceding claims, wherein the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Table 2 below lists the values of CCV measured at a reference moisture worth of 12.5 percent oven volatiles for every pattern.
Conventionally, cut filler tobacco products for smoking articles are formed 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 continues Fashion tobacco pipe to be after the lamina has been eliminated and separated is not used. However, it isn’t unusual to add some tobacco stems again into the cut filler along with the lamina.
By method of instance, tobacco stems could additionally be floor to a fantastic powder after which mixed with tobacco mud, guar gum, and water to form an aqueous slurry. This aqueous slurry could additionally be solid and dried to type a reconstituted tobacco sheet. As an alternative, suitable tobacco supplies may be combined in an agitated tank with water to obtain a pulp. This internet is fed onwards to a press, where the excess water is squeezed out of the online. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco minimize 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 gadget 36.
The yield of flat rolled stem which can be used directly as filler is increased, and the average stem size and thus the typical size of reduce filler from stem is elevated. A tobacco minimize filler based on any one of the preceding claims having a filling power of at least 3.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Accordingly, tobacco particles had been prepared from the same sheet of reconstituted tobacco in accordance with the minimize specification illustrated in Figure 12, wherein the cut width SCW1 is of zero.9 millimetres, the minimize length CL1 is of four.94 millimetres and the global width CW1 is of 12.50 millimetres.
