In addition, the formation of tobacco mud is reduced in contrast with traditional manufacturing strategies. Accordingly, the necessity to collect and re-process tobacco dust is significantly decreased and the general efficiency of the manufacturing process is thus advantageously increased. A tobacco minimize filler in accordance with any one of many previous claims, whereby the primary tobacco materials is shredded into strips having a sinusoidal shape, whereby a wave length of the sinusoidal form is from about 1 mm to about 15 mm. A tobacco minimize filler in accordance with any one of many 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 beneath lists the values of CCV measured at a reference moisture worth of 12.5 % oven volatiles for every pattern.
A tobacco cut filler based on claim 1 or 2, wherein the first tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the reduce 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 explicit, there was concern that through the cigarette-making course of the tobacco particle can be uncovered to high tensions and frictions which tobacco pipe might cause particles ready in accordance with the cut specification no. 10 to break. This may have lowered 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 reduce filler in accordance with the present invention. Figures depict several examples of notably shapes into which tobacco material for forming a minimize filler in accordance with the current invention may be minimize.
Sensors 40 and mass flow controllers 42, 44, if current, are operatively linked with a management unit forty six configured to regulate the operation of the equipment. In explicit, the control unit forty six adjusts the speed to the conveyor belt 38 in view of variations within the velocity at which the online of reconstituted tobacco is fed to the shredding gadget 36, so as to stop any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the dimensions and form of the strips into which the first tobacco materials is reduce or shredded, the options of the primary tobacco material can advantageously be better preserved each time the primary tobacco material is mixed, in the shredded state, with any other tobacco material. This is particularly advantageous when the first tobacco materials is a pre-processed tobacco materials, such as a reconstituted tobacco sheet material. The “thickness” of a reduce strip of tobacco material for incorporation in minimize fillers based on the present invention refers back to the distance between an higher surface and a decrease floor of the portion of fabric forming the cut strip.
The term “cut specification” is used all through the specification to check with the various geometric parameters characterising the strips obtained by subjecting a tobacco materials to a cutting operation. Thus, in accordance to a given “cut specification”, a tobacco material shall be minimize or shredded into strips having a predetermined cut width, reduce length, cut shape and so forth. Further, it might be desirable to provide one such improved course of that permits for a better management of the shape, size and properties of the reconstituted tobacco matter forming a part of the cut filler. At the identical time, it might be desirable to offer one such process that does not require any main modification of the conventional apparatus and services used in the main remedy of tobacco.
The yield of flat rolled stem which may be used instantly as filler is increased, and the average stem length and thus the typical size of reduce filler from stem is elevated. A tobacco cut filler in accordance with any one of many preceding claims having a filling energy of at least three.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. Accordingly, tobacco particles have been ready from the same sheet of reconstituted tobacco according to the minimize specification illustrated in Figure 12, wherein the minimize width SCW1 is of zero.9 millimetres, the cut length CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
Even extra ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of no less than about 0.2 mm. In addition, or instead, the primary tobacco material is preferably shredded into strips from a sheet material 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 lower than about 0.95 mm. Even more ideally, the primary tobacco material is shredded into strips from a sheet material having a thickness of less than about 0.eighty five mm.
In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 percent by weight of reconstituted tobacco particles reduce in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the minimize width of a person cut strip is taken at the point alongside the length of the strip that yields the biggest cross-sectional space. Further, the filling energy of the shredded first tobacco material may be maximised by selecting a suitable first cut specification. This results in an improved filling power of the reduce filler as a complete, particularly when the first tobacco material is mixed with at least another tobacco materials.
Should one such particle break at a location within the central V-shaped portion, the two ensuing components of the particles would nonetheless be effectively V-shaped. The highest CCV values had been obtained for minimize specification no. three, which considerably 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 significant 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 in the following Table 3 had been measured. Tobacco reduce fillers based on the present invention could additionally be prepared by a method comprising providing a first tobacco material and cutting the first tobacco materials in accordance with a first cut specification setting at least predetermined first cut width and first cut size. Tobacco reduce filler in accordance with the current invention may be included into a wide range of smoking articles.
Further, the second Y-shaped structure includes a second branching node from which an oblong structure branches off. In the embodiment of Figure 1 1 , the cut strip contains a first Y-shaped structure including a first branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped construction contains a second branching node from which a third Y-shaped structure branches off.
A tobacco reduce filler in accordance with any one of many preceding claims, whereby the first tobacco materials is shredded into strips having a reduce length from about 5 mm to about 60 mm. A tobacco minimize filler based on any one of claims 2 to four, wherein the second tobacco materials is a pure tobacco leaf materials. An angle of ninety degrees was thought-about to be undesirable, in that it might lead primarily to a shape quite just like the form of Figure 6, and so an angle of 60 degrees was chosen for the “V” elements. Further, the tactic ideally includes the step of mixing the reduce first tobacco materials and the minimize second tobacco material.
