The shredding system is configured to chop the reconstituted tobacco in accordance to a first minimize specification, whereby both minimize width and minimize length are predetermined. The reduce strips are dropped onto a conveyor belt 38 arranged beneath the shredding device 36 and defining a collection surface upon which the minimize strips fall out of the shredding gadget. Additional means T may be provided for tensioning the online of reconstituted tobacco as it’s unwound off the bobbin. Further, the apparatus 30 may comprise sensors 40 for detecting the moisture content material of the web of reconstituted tobacco upstream of the shredding system 36. In addition, the apparatus 30 might comprise mass circulate controllers 42, forty four tailored to regulate the velocity at which the online of reconstituted tobacco is fed to the shredding system 36 and the pace of the conveyor belt 38.
Should one such particle break at a location in the central V-shaped portion, the 2 ensuing parts of the particles would nonetheless be effectively V-shaped. The highest CCV values have been obtained for cut specification no. three, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco based on cut specification no. 3 are produced, a significant fraction of the tobacco materials went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed in the following Table 3 were measured. Tobacco cut fillers based on the present invention may be prepared by a method comprising providing a primary tobacco materials and cutting the first tobacco materials in accordance with a primary cut specification setting at least predetermined first cut width and first cut length. Tobacco cut filler in accordance with the current invention may be included into a selection of smoking articles.
For example, a bimodal distribution may correspond effectively to two groups of cut strips having different average cut lengths , one group being larger than the opposite. Preferably, the primary tobacco material is shredded into strips from a sheet materials having a thickness of no much less than about zero.05 mm. More preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of no less than about 0.1 mm.
A tobacco minimize filler based on declare 1 or 2, whereby the primary tobacco material is a pre- processed tobacco material. In a 3rd experiment, the cut specification no. 10 was slightly modified with a view to improving the resistance of the particles to the stresses concerned by the cigarette-making course of. In specific, there was concern that in the course of the cigarette-making process the tobacco particle could be exposed to excessive tensions and frictions which might cause Filling cut tobacco particles prepared in accordance with the reduce specification no. 10 to break. This might have reduced the benefit 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 minimize filler in accordance with the current invention. Figures depict a quantity of examples of notably shapes into which tobacco materials for forming a reduce filler in accordance with the current invention may be cut.
In addition, the formation of tobacco dust is decreased in contrast with traditional manufacturing methods. Accordingly, the need to collect and re-process tobacco mud is considerably reduced and the overall efficiency of the manufacturing course of is thus advantageously increased. A tobacco reduce filler in accordance with any one of many previous claims, wherein the first tobacco material is shredded into strips having a sinusoidal form, wherein a wave size of the sinusoidal shape is from about 1 mm to about 15 mm. A tobacco reduce filler based on any one of the preceding claims, whereby the primary tobacco material is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Table 2 below lists the values of CCV measured at a reference moisture worth of 12.5 % oven volatiles for every sample.
In apply, one such reduce strip could additionally be described as approximately wave-shaped or zigzag-shaped. Accordingly, geometric parameters similar to the peak amplitude, peak-to-peak amplitude, period of a sine wave may be used to explain the shape of 1 such cut strips. A tobacco cut filler contains a first tobacco material cut in accordance with a primary tobacco pipe reduce specification, wherein the first minimize specification units a minimum of predetermined first reduce width and first minimize length. A tobacco minimize filler according to any one of the previous claims, wherein the primary tobacco materials is shredded into strips having a reduce width from about 0.2 mm to about 1 mm.
More preferably, the first tobacco materials is shredded into strips having a cut width of no less than about 0.25 mm. Even more preferably, the first tobacco material is shredded into strips having a reduce width of no much less than about zero.3 mm. In addition, or instead, the first tobacco material is preferably shredded into strips having a minimize width of lower than about 1 mm.
Suitable natural tobacco leaf materials embody tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf materials used as the second tobacco materials could include any type of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mix thereof. A tobacco reduce filler based on the present invention contains a primary tobacco materials minimize in accordance with a first Fashion tobacco pipe cut specification, whereby the first minimize specification sets no less than predetermined first reduce width and first cut length. The time period “filling energy” is used to describe the volume of area taken up by a given weight or mass of a tobacco material. The greater the filling energy of a tobacco material, the decrease the weight of the material required to fill a tobacco rod of ordinary dimensions.
