Figures 1 to 12 shows reduce strips of a first tobacco material for incorporation in a reduce filler in accordance with the present 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 reduce tobacco pipe specification, wherein the primary cut specification units a predetermined first reduce width CW1 and a predetermined first cut length CL1 . In addition, the primary reduce specification might further set a predetermined first sectional minimize width SCW1.
The time period “reduce specification” is used all through the specification to discuss with the various geometric parameters characterising the strips obtained by subjecting a tobacco materials to a slicing operation. Thus, in accordance to a given “minimize specification”, a tobacco materials shall be minimize or shredded into strips having a predetermined minimize width, cut length, reduce form and so forth. Further, it might be desirable to offer one such improved course of that enables for a greater control of the form, measurement and properties of the reconstituted tobacco matter forming part of the cut filler. At the same time, it would be desirable to offer one such process that does not require any main modification of the conventional equipment and facilities used in the main remedy of tobacco.
In other embodiments, the reduce length distribution among the cut strips of the first tobacco material may be multimodal, including particularly bimodal and trimodal. The “cut length” of a strip of minimize tobacco material for incorporation in minimize fillers based on the present invention refers to the maximum dimension of the strip of the tobacco materials Fashion tobacco pipe ensuing from the cutting operation, that’s the most measurable distance between two factors on the cut strip. When taking a look at a cut strip under a microscope, it will generally be potential to watch the course along which the minimize strip extends over such greater size .
Alternative methods for the manufacture of reconstituted tobacco sheets are additionally identified to the skilled person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with an online, 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 one of a quantity of methods known in the artwork. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced in the course of the manufacturing process.
In preferred embodiments, the primary tobacco materials is a pre-processed tobacco materials. By “pre-processed tobacco material” reference is made all through the specification to a tobacco material produced by man from pure tobacco as opposed to occurring naturally as such. It would subsequently be fascinating to provide an alternative tobacco minimize filler having improved filling energy. At the identical time, it would be fascinating to provide a novel process for manufacturing tobacco minimize filler, whereby the filling power of the tobacco minimize filler is improved and the production of tobacco dust is decreased. The current invention pertains to the manufacturing of tobacco cut filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the minimize filler according to the invention.
Where OV is the precise p.c oven volatiles of the pattern of tobacco minimize filler and f is a correction factor (0.4 for the take a look at indicated). In RYO, the stem can both be separated from the lamina by hand (for hand-stripped tobacco) or the stem and lamina usually are not separated in any respect (loose-leaf tobacco) – this type is used for Scandinavian Tobacco Group’s Norwegian RYO brand Tiedemanns. A method according to any certainly one of claims 15 to twenty, additional comprising adjusting the moisture content of the second tobacco materials. A fishbone-shaped strip is shown in Figure 6, whereas Figures 7 and eight show two embodiments of rectangular strips. Abstract The quantity of tobacco which is critical for the proper filling of a cigarette depends on different factors and significantly on the filling weight of tobacco rag at a given stress. Some years ago the ”Centre d’Essais” of the SEITA developed an equipment by which the filling weight being related to the filling capacity may be measured.
More ideally, the cut filler has a filling energy of lower than about 7 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. In some particularly most popular embodiments, the reduce filler has a filling power of from about 3.5 cubic centimetres per gram to about eight cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. Preferably, the first tobacco materials is shredded into strips having a minimize size of at least about 5 mm. More preferably, the first tobacco material is shredded into strips having a reduce size of no much less than about 10 mm.
Experiments had been carried out so as to assess the impression of various shapes and reduce specs to key parameters of tobacco reduce filler particles, such as the filling energy. In extra detail, Figure 1 exhibits a zigzag-shaped strip and Figure 2 shows a wave-shaped strip. Where the minimize strip is zigzag-shaped or wave- shaped, it is potential to measure a wave length of the reduce strip, which considerably corresponds to the strip cut length divided by the number of repetitions of the zigzag or wave. For occasion, within the cut strip of Figure 1 the zigzag is repeated 10 times. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, more ideally from about 2 mm to about 12 mm, much more ideally from four mm to 10 mm. Preferably, the tobacco reduce filler additional comprises a second tobacco materials minimize in accordance with a second minimize specification differing from the primary reduce specification for at least certainly one of cut length and minimize width.
Without wishing to be bound to principle, will in all probability be appreciated that during any cutting, rolling or extruding operation, the tobacco fibres usually align in a given direction, which can thus be recognized because the longitudinal direction of the tobacco material. The “cut length” of a cut strip of tobacco material for incorporation in cut fillers in accordance with the present invention could due to this fact be measured along the primary direction of fibre alignment, which usually corresponds to the longitudinal path. Thus, the reduce length of a person minimize strip may be precisely measured using a conventional measuring gadget underneath a microscope. In a traditional process, reconstituted tobacco or tobacco stem material or both are typically blended with threshed tobacco lamina to undergo a series of treatments, such as conditioning and drying. To this function, a reconstituted tobacco sheet is usually ripped into randomly shaped sheet-like items having a non-uniform measurement, usually of several sq. centimetres.
In statistics, a unimodal distribution is a distribution which has a single mode. In a discrete chance distribution – as is the case with the distribution of reduce length or reduce width values in a inhabitants of particles of the first tobacco material – the mode is a worth at which the probability mass function takes its maximum value. In other words, in the current specification, the mode of a unimodal distribution will establish a most probably worth of reduce width or cut length in a inhabitants of particles of the tobacco materials. In practice, if the amount of particles having a certain cut size or cut width is plotted against the growing cut length or cut width, the chart of the amount of particles will usually have a single most.
