By way of instance, tobacco stems may be floor to a fine powder after which combined with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry may be cast and dried to kind a reconstituted tobacco sheet. As an alternate, appropriate tobacco supplies may be mixed in an agitated tank with water to acquire a pulp. This internet is fed onwards to a press, the place the surplus water is squeezed out of the online. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco minimize filler in accordance with the present invention. A internet 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure 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 cut width of a person minimize strip is taken on the point along the length of the strip that yields the biggest cross-sectional area. Further, the filling energy of the shredded first tobacco material can be maximised by deciding on an acceptable first cut specification. This leads to an improved filling power of the minimize filler as a complete, particularly when the primary tobacco material is mixed with a minimum of one other tobacco material.
In preferred embodiments, the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even extra preferably, the first tobacco materials is shredded into strips from a sheet material having a thickness from about zero.1 mm to about zero.3 mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco reduce filler based on any considered one of claims 1 to 9, wherein the primary Filling cut tobacco tobacco material is shredded into strips each comprising a minimum of a primary strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of minimize strips together with one or more V-shaped structure. Each V construction includes two substantially straight elements forming an angle.
For instance, a bimodal distribution might correspond effectively to two groups of minimize strips having different average minimize 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 0.05 mm. More ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of no much less than about zero.1 mm.
The time period “minimize 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 materials shall be cut or shredded into strips having a predetermined minimize width, reduce length, cut form and so forth. Further, it might be desirable to provide one such improved course of that allows for a better management of the form, size and properties of the reconstituted tobacco matter forming part of the cut filler. At the identical time, it would be fascinating to offer one such process that doesn’t require any major modification of the standard apparatus and services used within the primary therapy of tobacco.
A tobacco minimize filler based on declare 1 or 2, wherein the first tobacco material is a pre- processed tobacco material. In a third experiment, the cut specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In specific, there was concern that through the cigarette-making course of the tobacco particle would be exposed to excessive tensions and frictions which might cause particles prepared in accordance with the reduce specification no. 10 to interrupt. This may have decreased the benefit coming from the V-shape and shown by the CCV measurements described above. Figure 13 depicts a schematic view of an equipment for forming a tobacco reduce filler in accordance with the current invention. Figures depict several examples of particularly shapes into which tobacco material for forming a minimize filler in accordance with the present invention may be minimize.
Sensors 40 and mass move controllers 42, forty four, if current, are operatively connected with a control unit forty six configured to control the operation of the equipment. In specific, the management unit forty six adjusts the pace to the conveyor belt 38 in view of variations within the speed at which the net of reconstituted tobacco is fed to the shredding device 36, in order to stop any undesirable accumulation of cut strips on the conveyor belt. By finely controlling the scale and form of the strips into which the first tobacco materials is cut or shredded, the features of the primary tobacco material can advantageously be better preserved each time the primary tobacco material is blended, in the shredded state, with any other tobacco materials. 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 material for incorporation in reduce fillers according to the current invention refers to the distance between an higher surface and a lower floor of the portion of material forming the minimize strip.
Figures 1 to 12 shows reduce strips of a primary tobacco material for incorporation in a minimize filler in accordance with the current invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a first minimize specification, wherein the first cut specification units a predetermined first reduce width CW1 and a predetermined first reduce size CL1 . In addition, the primary cut specification might further set a predetermined first sectional minimize width SCW1.
The yield of flat rolled stem which can be used directly as filler is elevated, and the average stem size and thus the average size of minimize filler from stem is increased. A tobacco minimize filler based on any one of the previous claims having a filling energy of a minimal of 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. Accordingly, tobacco particles have been ready from the identical sheet of reconstituted tobacco in accordance with the cut specification illustrated in Figure 12, wherein the cut width SCW1 is of zero.9 millimetres, the minimize length CL1 is of four.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
