The time period “reduce specification” is used throughout the specification to refer to the assorted geometric parameters characterising the strips obtained by subjecting a tobacco material to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco materials shall be minimize or shredded into strips having a predetermined reduce width, minimize size, minimize form and so forth. Further, it would be desirable to provide one such improved course of that permits for a greater control of the shape, size and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the identical time, it might be fascinating to provide one such course of that doesn’t require any major modification of the traditional apparatus and services used in the main treatment of tobacco.
Reconstituted tobacco is formed from tobacco material similar to tobacco stems, tobacco stalks, leaf scraps and tobacco dust, that are produced in the course of the manufacturing processes of tobacco merchandise. Such tobacco material may, for instance, be ground to a fantastic powder and then mixed with water and sometimes Fashion tobacco pipe with a binder, similar to guar gum, to form a slurry. This slurry is then solid onto a supportive floor, similar to a belt conveyor, and dried to kind a sheet (so known as ‘cast leaf) that can be removed from the supportive surface and wound into bobbins.
Sensors forty and mass flow controllers 42, 44, if current, are operatively linked with a management unit 46 configured to regulate the operation of the equipment. In explicit, the control unit 46 adjusts the velocity to the conveyor belt 38 in view of variations in the pace at which the web of reconstituted tobacco is fed to the shredding gadget 36, so as to prevent any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the size and shape of the strips into which the primary tobacco materials is minimize or shredded, the features of the primary tobacco materials can advantageously be better preserved each time the first tobacco material is mixed, within the shredded state, with another tobacco materials. This is especially advantageous when the primary tobacco material is a pre-processed tobacco materials, corresponding to a reconstituted tobacco sheet material. The “thickness” of a reduce strip of tobacco material for incorporation in reduce fillers based on the current invention refers back to the distance between an upper floor and a lower surface of the portion of fabric forming the reduce strip.
A tobacco cut filler according to any one of the previous claims, wherein the primary tobacco materials is shredded into strips having a cut length from about 5 mm to about 60 mm. A tobacco reduce filler based on any one of claims 2 to four, wherein the second tobacco materials is a pure tobacco leaf material. An angle of 90 levels was thought-about to be undesirable, in that it would lead primarily to a form quite similar to the shape of Figure 6, and so an angle of 60 degrees was chosen for the “V” components. Further, the method ideally comprises the step of mixing the minimize first tobacco materials and the reduce second tobacco materials.
Experiments had been carried out so as to assess the impression of various shapes and cut specs to key parameters of tobacco reduce filler particles, such as the filling energy. In extra detail, Figure 1 shows a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- formed, it’s potential to measure a wave length of the minimize strip, which substantially corresponds to the strip cut length divided by the variety of repetitions of the zigzag or wave. For instance, within the cut strip of Figure 1 the zigzag is repeated 10 times. Preferably, a wave size of the sinusoidal shape is from about 1 mm to about 15 mm, extra preferably from about 2 mm to about 12 mm, even more preferably from four mm to 10 mm. Preferably, the tobacco minimize filler further contains a second tobacco materials minimize in accordance with a second minimize specification differing from the first reduce specification for a minimal of considered one of minimize length and reduce width.
In most popular embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even extra ideally, the primary tobacco material is shredded into strips from a sheet material having a thickness from about zero.1 mm to about zero.three mm, most preferably from a sheet materials having a thickness of about zero.2 mm. A tobacco minimize filler according to any certainly one of claims 1 to 9, wherein the first tobacco materials is shredded into strips each comprising at least a first strip construction comprising a branching node from which a further strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of cut strips together with one or more V-shaped construction. Each V structure contains two substantially straight parts forming an angle.
Without wishing to be sure to theory, it will be appreciated that in any cutting, rolling or extruding operation, the tobacco fibres typically align in a given path, which can thus be identified because the longitudinal course of the tobacco materials. The “cut length” of a minimize strip of tobacco material for incorporation in cut fillers based on the current invention could subsequently be measured alongside the primary path of fibre alignment, which usually corresponds to the longitudinal direction. Thus, the reduce length of a person minimize strip can be precisely measured using a conventional measuring device beneath a microscope. In a standard course of, reconstituted tobacco or tobacco stem materials or each are usually blended with threshed tobacco lamina to undergo a sequence of therapies, corresponding to conditioning and drying. To this function, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like pieces having a non-uniform dimension, typically of a quantity of square centimetres.
