The term “cut specification” is used throughout the specification to discuss with the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a cutting operation. Thus, in accordance to a given “reduce specification”, a tobacco materials shall be reduce or shredded into strips having a predetermined cut width, cut size, cut form and so forth. Further, it might be fascinating to supply tobacco pipe one such improved course of that permits for a better management of the form, dimension and properties of the reconstituted tobacco matter forming part of the cut filler. At the identical time, it might be fascinating to offer one such process that does not require any main modification of the traditional equipment and facilities used in the major remedy of tobacco.
Sensors 40 and mass flow controllers 42, forty four, if current, are operatively related with a management unit 46 configured to regulate the operation of the apparatus. In explicit, the control unit forty six adjusts the speed to the conveyor belt 38 in view of variations in the pace at which the online of reconstituted tobacco is fed to the shredding system 36, in order to forestall any undesirable accumulation of cut strips on the conveyor belt. By finely controlling the size and shape of the strips into which the primary tobacco materials is reduce or shredded, the options of the first tobacco material can advantageously be higher preserved each time the first tobacco materials is mixed, in the shredded state, with another tobacco material. This is particularly advantageous when the primary tobacco materials is a pre-processed tobacco material, similar to a reconstituted tobacco sheet materials. The “thickness” of a reduce strip of tobacco material for incorporation in cut fillers based on the present invention refers again to the distance between an upper floor and a decrease surface of the portion of material forming the cut strip.
Further, the second Y-shaped structure comprises a second branching node from which a rectangular structure branches off. In the embodiment of Figure 1 1 , the cut strip includes a first Y-shaped structure together with a primary branching node from which a second Y-shaped structure branches off. Further, the second Y-shaped structure includes a second branching node from which a 3rd Y-shaped structure branches off.
In addition, a second couple of blends was used, that contained 70 % by weight of pure tobacco particles and 30 p.c by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the cut width of a person minimize strip is taken on the point along the size of the strip that yields the largest cross-sectional area. Further, the filling energy of the shredded first tobacco materials could be maximised by choosing a suitable first reduce specification. This results in an improved filling power of the minimize filler as a complete, notably when the first tobacco materials is blended with at least another tobacco materials.
A tobacco reduce filler in accordance with declare 1 or 2, wherein the first tobacco material is a pre- processed tobacco material. In a third experiment, the reduce specification no. 10 was slightly modified with a view to enhancing the resistance of the particles to the stresses concerned by the cigarette-making process. In explicit, there was concern that through the cigarette-making course of the tobacco particle would be uncovered to excessive tensions and frictions which might trigger particles ready in accordance with the reduce specification no. 10 to break. This may 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 equipment for forming a tobacco cut filler in accordance with the current invention. Figures depict several examples of notably shapes into which tobacco materials for forming a minimize filler in accordance with the current invention may be reduce.
Without wishing to be sure to principle, it will be appreciated that in any cutting, rolling or extruding operation, the tobacco fibres typically align in a given direction, which can thus be identified as the longitudinal path of the tobacco material. The “cut length” of a cut strip of tobacco materials for incorporation in reduce fillers according to the present invention may therefore be measured alongside the principle path of fibre alignment, which usually corresponds to the longitudinal course. Thus, the cut size of an individual cut strip may be precisely measured utilizing a conventional measuring device under a microscope. In a standard process, reconstituted tobacco or tobacco stem material or each are typically blended with threshed tobacco lamina to undergo a collection of treatments, such as conditioning and drying. To this objective, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like pieces having a non-uniform dimension, typically of several sq. centimetres.
