Figures 1 to 12 exhibits cut strips of a primary tobacco materials for incorporation in a minimize filler in accordance with the current invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a first cut specification, whereby the first reduce specification sets a predetermined first minimize width CW1 and a predetermined first reduce length CL1 . In addition, the first minimize specification might further set a predetermined first sectional reduce width SCW1.
Without wishing to be certain to principle, will most likely be appreciated that during any cutting, rolling or extruding operation, the tobacco fibres generally align in a given path, which may thus be identified because the longitudinal direction of the tobacco material. The “reduce size” of a cut strip of tobacco materials for incorporation in reduce fillers in accordance with the current invention may due to this fact be measured alongside the principle path of fibre alignment, which typically corresponds to the longitudinal direction. Thus, the cut length of an individual reduce strip could be precisely measured utilizing a standard measuring device beneath a microscope. In a conventional course of, reconstituted tobacco or tobacco stem materials or both are typically blended with threshed tobacco lamina to bear a collection of treatments, similar to conditioning and drying. To this purpose, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like pieces having a non-uniform dimension, usually of a quantity of sq. centimetres.
Even extra preferably, the primary tobacco material is shredded into strips from a sheet material having a thickness of at least about zero.2 mm. In addition, or as an alternative, the first tobacco materials is preferably shredded into strips from a sheet material having a thickness of less than about 1 mm. More preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of lower than about zero.ninety five mm. Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about zero.eighty five mm.
The expressions “last reduce width” and “last minimize length” are used herein to explain the cut width and cut size of a tobacco materials as present in a tobacco cut filler utilized in a tobacco product. The methodology may further comprise a step of conditioning the first tobacco materials previous to slicing the first tobacco materials. Further, the method might comprise a step of controlling the moisture content of the minimize filler by adjusting the moisture content material of the first tobacco material.
Sensors forty and mass circulate controllers 42, forty four, if current, are operatively related with a management unit 46 configured to manage the operation of the apparatus. In specific, the management unit forty six adjusts the speed to the conveyor belt 38 in view of variations within the speed at which the online of reconstituted tobacco is fed to the shredding gadget 36, in order to prevent any undesirable accumulation of cut strips on the conveyor belt. By finely controlling the scale and form of the strips into which the primary tobacco materials is reduce or shredded, the features of the primary tobacco pipe tobacco material can advantageously be higher preserved every time the primary tobacco materials is mixed, in the shredded state, with some other tobacco material. This is particularly advantageous when the primary tobacco materials is a pre-processed tobacco materials, similar to a reconstituted tobacco sheet material. The “thickness” of a minimize strip of tobacco materials for incorporation in reduce fillers according to the current invention refers again to the distance between an higher surface and a lower floor of the portion of fabric forming the cut strip.
Reconstituted tobacco is fashioned from tobacco material corresponding to tobacco stems, tobacco stalks, leaf scraps and tobacco mud, which are produced in the course of the manufacturing processes of tobacco merchandise. Such tobacco materials may, for instance, be ground to a fine powder after which blended with water and sometimes with a binder, such as guar gum, to type a slurry. This slurry is then forged onto a supportive floor, corresponding to a belt conveyor, and dried to kind a sheet (so known as ‘solid leaf) that might be faraway from the supportive surface and wound into bobbins.
Even extra ideally, first tobacco material is shredded into strips having a minimize length of a minimal of about 15 mm. In addition, or as an alternative, the primary tobacco materials is preferably shredded into strips having a minimize length of lower than about 60 mm. More ideally, the primary tobacco material is shredded into strips having a reduce length of less than about 50 mm. Even more preferably, the primary Fashion tobacco pipe tobacco materials is shredded into strips having a minimize length of lower than about 40 mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a reduce length from about 5 mm to about 60 mm. The term “sectional minimize width” is used in the present specification to explain the side- to-side width of 1 such portion of a minimize strip of tobacco material.
The values of filling energy are expressed in phrases of corrected cylinder volume which is the cylinder volume of the tobacco materials at a reference moisture level of 12.5 percent oven volatiles. The cylinder quantity could additionally be determined utilizing a Borgwaldt densimeter DD60 or DD60A kind fitted with a measuring head for cut tobacco and a tobacco cylinder container. The term “sinusoidal” is used to explain a reduce strip of tobacco material shaped substantially like a portion of a sine wave.
Experiments were carried out in order to assess the influence of various shapes and reduce specs to key parameters of tobacco minimize filler particles, such as the filling power. In more element, Figure 1 exhibits a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- shaped, it’s attainable to measure a wave length of the cut strip, which substantially corresponds to the strip reduce 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 occasions. Preferably, a wave size of the sinusoidal form is from about 1 mm to about 15 mm, more preferably from about 2 mm to about 12 mm, much more ideally from 4 mm to 10 mm. Preferably, the tobacco reduce filler further contains a second tobacco materials cut in accordance with a second cut specification differing from the first reduce specification for no less than one of minimize length and reduce width.
