Sensors 40 and mass flow controllers forty two, 44, if present, are operatively connected with a management unit forty six configured to control the operation of the equipment. In explicit, the control unit 46 adjusts the velocity to the conveyor belt 38 in view of variations within the speed at which the web of reconstituted tobacco is fed to the shredding system 36, in order to prevent any undesirable accumulation of reduce strips on the conveyor belt. By finely controlling the scale and shape of the strips into which the primary tobacco material is reduce or shredded, the options of the first tobacco material can advantageously be higher preserved every time the primary tobacco materials is blended, within the shredded state, with any other tobacco material. This is particularly advantageous when the primary tobacco material is a pre-processed tobacco materials, similar to a reconstituted tobacco sheet materials. The “thickness” of a minimize strip of tobacco materials for incorporation in minimize fillers according to the current invention refers again to the distance between an higher floor and a decrease surface of the portion of material forming the reduce strip.
The term “cut specification” is used throughout the specification to refer to the assorted geometric parameters characterising the strips obtained by subjecting a tobacco materials to a chopping 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, minimize form and so forth. Further, it would be desirable to offer one such improved course of that allows for a greater management of the shape, dimension and properties of the reconstituted tobacco matter forming part of the reduce filler. At the identical time, it might be desirable to provide one such course of that does not require any main modification of the standard apparatus and services used in the major remedy of tobacco.
A tobacco minimize filler based on declare 1 or 2, whereby the primary tobacco materials is a pre- processed tobacco material. In a 3rd experiment, the cut specification no. 10 was barely modified with a view to enhancing the resistance of the particles to the stresses involved by the cigarette-making process. In particular, there was concern that in the course of the cigarette-making course of the tobacco particle can be uncovered to excessive tensions and frictions which could cause Fashion tobacco pipe particles prepared in accordance with the reduce specification no. 10 to interrupt. This might have lowered the profit coming from the V-shape and shown 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 significantly shapes into which tobacco materials for forming a cut filler in accordance with the current invention could additionally be cut.
More ideally, the primary tobacco materials is shredded into strips having a minimize width of no less than about zero.25 mm. Even extra ideally, the first tobacco material is shredded into strips having a reduce width of at least about 0.three mm. In addition, or instead, the primary tobacco materials is preferably shredded into strips having a minimize width of less than about 1 mm.
In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 % by weight of reconstituted tobacco particles reduce in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of a person reduce strip is taken at the level along the length of the strip that yields the biggest cross-sectional area. Further, the filling energy Filling cut tobacco of the shredded first tobacco materials can be maximised by selecting an appropriate first cut specification. This ends in an improved filling power of the cut filler as a complete, particularly when the first tobacco materials is mixed with no much less than one other tobacco materials.
