Alternative methods for the manufacture of reconstituted tobacco sheets are additionally recognized to the skilled particular person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to discuss with an internet, preferably with considerably uniform thickness, which could be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by considered one of a quantity of strategies recognized within the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced through the manufacturing course of.
In preferred embodiments, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about 0.2 mm. A tobacco minimize filler in accordance with any certainly one of claims 1 to 9, wherein the first tobacco pipe tobacco materials is shredded into strips each comprising a minimum of a primary strip structure comprising a branching node from which an extra strip structure branches off, forming an angle with the primary strip construction. Figures 10 and 12 present two examples of cut strips together with a number of V-shaped structure. Each V structure comprises two considerably straight elements forming an angle.
Half Zware Normally made from Virginia, dark-fired, darkish air-cured tobaccos. Zware Contains a greater proportion of dark-fired or air-cured tobaccos and fewer Virginia tobacco than Half Zware. Zware means “heavy” or “darkish”, so Zware tobacco is darker – in each color and taste – than Half Zware. A method according to claim 15 or 16, wherein the primary tobacco materials is a pre-processed tobacco material. With pressed cuts, the tobacco is positioned beneath extreme stress and ranging degrees of warmth for an extended period of time. A bit of fermentation additionally happens in the course of the process, which supplies the tobacco a fuller, rounder style.
In some embodiments, tobacco minimize filler based on the invention may be used within the tobacco rod of a combustible smoking article, similar to a filter cigarette, cigarillo or cigar. Alternatively, the minimize filler may be used to provide the tobacco aerosol generating substrate in a distillation based smoking article, or an electrically heated smoking system. Alternatively, the reduce filler could additionally be used as a roll-your-own or make-your-own product, or loose tobacco product for use in a pipe.
A tobacco reduce filler based on claim 1 or 2, whereby the first tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the minimize specification no. 10 was barely modified with a view to enhancing the resistance of the particles to the stresses involved by the cigarette-making course of. In explicit, there was concern that through the cigarette-making process the tobacco particle would be uncovered to high tensions and frictions which Fashion tobacco pipe could trigger particles ready in accordance with the cut specification no. 10 to break. This could have reduced the profit coming from the V-shape and shown by the CCV measurements described above. Figure thirteen depicts a schematic view of an apparatus for forming a tobacco cut filler in accordance with the present invention. Figures depict several examples of notably shapes into which tobacco materials for forming a reduce filler in accordance with the current invention may be cut.
Figures 1 to 12 reveals cut strips of a first tobacco material for incorporation in a cut filler in accordance with the present 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 primary minimize specification, whereby the first cut specification sets a predetermined first cut width CW1 and a predetermined first reduce length CL1 . In addition, the first reduce specification may additional set a predetermined first sectional cut width SCW1.
Experiments had been carried out in order to assess the impact of different shapes and minimize specs to key parameters of tobacco cut filler particles, such because the filling power. In extra detail, Figure 1 shows a zigzag-shaped strip and Figure 2 shows a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- shaped, it is attainable to measure a wave size of the minimize strip, which substantially corresponds to the strip cut size divided by the number of repetitions of the zigzag or wave. For instance Filling cut tobacco, within the minimize strip of Figure 1 the zigzag is repeated 10 occasions. Preferably, a wave length of the sinusoidal form is from about 1 mm to about 15 mm, more 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 reduce in accordance with a second minimize specification differing from the first cut specification for a minimal of considered one of cut size and minimize width.
The values of filling energy are expressed in phrases of corrected cylinder volume which is the cylinder quantity of the tobacco material at a reference moisture degree of 12.5 % oven volatiles. The cylinder volume may be decided utilizing a Borgwaldt densimeter DD60 or DD60A kind fitted with a measuring head for minimize tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to describe a cut strip of tobacco material formed considerably like a portion of a sine wave.
