Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of no much less than about 0.2 mm. In addition, or in its place, the first tobacco materials is ideally shredded into strips from a sheet materials having a thickness of less than about 1 mm. More ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of less than about 0.95 mm. Even more ideally, the first tobacco materials is shredded into strips from a sheet material having a thickness of less than about 0.eighty five mm.
The yield of flat rolled stem which can be used instantly as filler is elevated, and the typical stem length and thus the average length of minimize filler from stem is increased. A tobacco cut filler based on any one of the previous claims having a filling power of no much less than 3.5 cubic centimetres per gram at a reference moisture value Filling cut tobacco of 12.5 % oven volatiles. Accordingly, tobacco particles were prepared from the same sheet of reconstituted tobacco according to the reduce specification illustrated in Figure 12, wherein the cut width SCW1 is of 0.9 millimetres, the minimize length CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
Sensors forty and mass move controllers forty two, 44, if present, are operatively linked with a control unit forty six configured to manage the operation of the equipment. In particular, the management unit 46 adjusts the pace to the conveyor belt 38 in view of variations in the pace at which the net of reconstituted tobacco is fed to the shredding system 36, in order to forestall any undesirable accumulation of reduce strips on the conveyor belt. By finely controlling the dimensions and shape of the strips into which the first tobacco material is cut or shredded, the features of the primary tobacco pipe tobacco materials can advantageously be better preserved whenever 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 material, corresponding to a reconstituted tobacco sheet material. The “thickness” of a cut strip of tobacco materials for incorporation in cut fillers according to the current invention refers back to the distance between an higher floor and a lower surface of the portion of material forming the minimize strip.
The term “reduce specification” is used all through the specification to discuss with the varied geometric parameters characterising the strips obtained by subjecting a tobacco materials to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco material shall be minimize or shredded into strips having a predetermined reduce width, reduce length, minimize form and so forth. Further, it would be fascinating to provide one such improved course of that allows for a greater management of the shape, size and properties of the reconstituted tobacco matter forming a part of the reduce filler. At the same time, it would be desirable to provide one such process that does not require any major modification of the standard equipment and services used within the primary treatment of tobacco.
Should one such particle break at a location within the central V-shaped portion, the 2 resulting components of the particles would still be effectively V-shaped. The highest CCV values had been obtained for reduce specification no. 3, which considerably corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the identical sheet of reconstituted tobacco according to cut specification no. 3 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 were measured. Tobacco cut fillers according to the current invention may be prepared by a method comprising providing a primary tobacco material and chopping the primary tobacco materials in accordance with a primary minimize specification setting no much less than predetermined first minimize width and first reduce size. Tobacco reduce filler in accordance with the present invention could also be included into a wide range of smoking articles.
The values of filling power are expressed when it comes to corrected cylinder volume which is the cylinder volume of the tobacco material at a reference moisture level of 12.5 percent oven volatiles. The cylinder quantity could additionally be decided utilizing a Borgwaldt densimeter DD60 or DD60A sort fitted with a measuring head for minimize tobacco and a tobacco cylinder container. The term “sinusoidal” is used to describe a reduce strip of tobacco materials shaped considerably like a portion of a sine wave.
In addition, a second couple of blends was used, that contained 70 % by weight of natural tobacco particles and 30 p.c by weight of reconstituted tobacco particles cut in accordance with the specs of Figures 1 1 and 12, respectively. Thus, the minimize width of a person minimize strip is taken at the level alongside the size of the strip that yields the most important cross-sectional space. Further, the filling power Fashion tobacco pipe of the shredded first tobacco material may be maximised by deciding on a suitable first reduce specification. This leads to an improved filling energy of the minimize filler as a complete, significantly when the primary tobacco materials is blended with no less than one other tobacco material.
