Experiments had been carried out in order to assess the influence of different shapes and reduce specifications to key parameters of tobacco minimize filler particles, such as the filling power. In extra element, Figure 1 exhibits a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the minimize strip is zigzag-shaped or wave- formed, it’s possible to measure a wave length of the reduce strip, which considerably corresponds to the strip reduce size divided by the number of repetitions of the zigzag or wave. For occasion, in the minimize strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave length 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 ideally from 4 mm to 10 mm. Preferably, the tobacco minimize filler additional comprises a second tobacco materials cut in accordance with a second minimize specification differing from the first reduce specification for at least considered one of minimize size and cut width.
More ideally, the primary tobacco materials is shredded into strips having a cut width of a minimal of about 0.25 mm. Even more preferably, the first tobacco materials is shredded into strips having a reduce width of at least about 0.three mm. In addition, or instead, the first tobacco material is ideally shredded into strips having a cut width of lower than about 1 mm.
In some embodiments, tobacco reduce filler according to the invention could also be used in the tobacco rod of a flamable smoking article, corresponding to a filter cigarette, cigarillo or cigar. Alternatively, the cut filler could also be used to offer the tobacco aerosol generating substrate in a distillation based mostly smoking article, or an electrically heated smoking system. Alternatively, the minimize filler may be used as a roll-your-own or make-your-own product, or loose tobacco product to be used in a pipe.
Figures 1 to 12 reveals cut strips of a first tobacco material for incorporation in a reduce filler in accordance with the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a primary cut specification, wherein the primary reduce specification units a predetermined first cut width CW1 and a predetermined first reduce size CL1 . In addition, the primary reduce specification could further set a predetermined first sectional cut width SCW1.
By distinction, in a multimodal distribution, the chance mass operate has a quantity of maxima, which signifies that among the many minimize strips of the primary tobacco materials there are a quantity of values of minimize size that occur most often. In the context of the present specification, a distribution having a quantity of local maxima is thought to be multimodal. It shall be appreciated that the different modes in a multimodal distribution can also have totally different frequencies, such that, among the many minimize strips of the first tobacco materials, one modal worth of minimize size will occur more frequently than one other modal value.
Alternative methods for the manufacture of reconstituted tobacco sheets are also known to the expert particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to an internet, ideally with substantially uniform thickness, that may be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by certainly one of a quantity of methods identified in the artwork. Suitable by-products include tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced in the course of the manufacturing course of.
Without wishing to be certain to principle, it will be appreciated that in any slicing, rolling or extruding operation, the tobacco fibres generally align in a given path, which may thus be recognized as the longitudinal path of the tobacco material. The “cut size” of a reduce strip of tobacco materials for incorporation in cut fillers in accordance with the current invention might due to this fact be measured along the primary course of fibre alignment, which typically corresponds to the longitudinal direction. Thus, the cut length of an individual cut strip can be accurately measured utilizing a traditional measuring gadget underneath a microscope. In a standard process, reconstituted tobacco or tobacco stem materials or both are sometimes blended with threshed tobacco lamina to undergo a series of treatments, similar to conditioning and drying. To this purpose, a reconstituted tobacco sheet is usually ripped into randomly shaped sheet-like items having a non-uniform size, typically of several sq. centimetres.
The values of filling energy are expressed by means of corrected cylinder volume which is the cylinder volume of the tobacco material at a reference moisture degree of 12.5 percent oven volatiles. The cylinder quantity may be determined using a Borgwaldt densimeter DD60 or DD60A type fitted with a measuring head for cut tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to explain a cut strip of tobacco materials shaped substantially like a portion of a sine wave.
A tobacco cut filler based on claim 1 or 2, wherein the first tobacco materials is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was slightly modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In explicit, there was concern that in the course of the cigarette-making process the tobacco particle would be uncovered to high tensions and frictions which could cause Filling cut tobacco particles ready in accordance with the cut specification no. 10 to interrupt. This may have decreased the profit coming from the V-shape and proven by the CCV measurements described above. Figure 13 depicts a schematic view of an apparatus for forming a tobacco cut filler in accordance with the present invention. Figures depict several examples of particularly shapes into which tobacco material for forming a minimize filler in accordance with the current invention may be minimize.
