The expressions “final cut width” and “final cut size” are used herein to explain the reduce width and cut size of a tobacco materials as found in a tobacco cut filler utilized in a tobacco product. The technique may additional comprise a step of conditioning the primary tobacco material prior to chopping the primary tobacco material. Further, the strategy may comprise a step of controlling the moisture content of the cut filler by adjusting the moisture content material of the primary tobacco materials.
As the name implies, it’s simply a mix of different tobacco varieties, cuts and flavors. They are straightforward to fill and smoke, and have greater robustness and taste selection than loose reduce Filling cut tobacco tobacco on its own. The first tobacco materials may be cut into strips having any suitable shape, including rectangular, trapezoidal, sinusoidal, Y-shaped, X-shaped and V-shaped.
Half Zware Normally made from Virginia, dark-fired, darkish air-cured tobaccos. Zware Contains a larger 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 style – than Half Zware. A methodology according to claim 15 or sixteen, whereby the first tobacco material is a pre-processed tobacco material. With pressed cuts, the tobacco is placed beneath excessive strain and varying levels of warmth for an extended time period. A little bit of fermentation also occurs during the process, which gives the tobacco a fuller, rounder taste.
Figures 1 to 12 reveals reduce strips of a primary tobacco materials for incorporation in a minimize 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 cut specification, whereby the primary cut specification sets a predetermined first cut width CW1 and a predetermined first reduce size CL1 . In addition, the primary cut specification may additional set a predetermined first sectional minimize width SCW1.
A tobacco cut filler according to any one of the preceding claims, wherein the first tobacco material is a reconstituted tobacco sheet. Preferably, the cut filler has a filling power of a minimum of about three.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. More preferably, the reduce filler has a filling power of at least about 4 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. In addition, or as an alternative, the reduce filler preferably has a filling energy of less than about 8 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles.
These irregular pieces are meant to be related in size to tobacco lamina, such that they are often blended with the tobacco lamina and cut. In explicit, the mix is typically reduce into particles having a predetermined minimize width. However, as a end result of the reconstituted tobacco sheet is somewhat randomly ripped into pieces, the tobacco fibres are typically not aligned in a uniform direction . Tobacco rods were ready from a tobacco cut filler utilizing tobacco particles minimize in accordance with the specs of Figures 1 1 and 12. In explicit, a primary couple of blends were used, that contained 85 % by weight of pure tobacco particles and 15 % by weight of reconstituted tobacco particles cut in accordance with specs of Figures 1 1 and 12, respectively.
In most well-liked embodiments, the first tobacco material is a pre-processed tobacco material. By “pre-processed tobacco materials” reference is made throughout the specification to a tobacco material produced by man from natural tobacco as opposed to occurring naturally as such. It would subsequently be fascinating to provide an alternate tobacco minimize filler having improved filling energy. At the identical time, it would be desirable to provide a novel process for manufacturing tobacco cut filler, whereby the filling energy of the tobacco reduce filler is improved and the manufacturing of tobacco mud is lowered. The present invention pertains to the manufacturing of tobacco cut filler comprising reconstituted tobacco and to a smoking article fashioned from a tobacco rod comprising the cut filler according to the invention.
By method of instance, it’s known to supply tobacco cut filler comprising reduce rolled stems having a predetermined rolled thickness and reduce to a predetermined width. In order to improve the style and burning characteristics of the tobacco stem to be used within the cut filler, the stems are often first subjected to a number of treatment procedures. In addition, or as an alternative, it’s recognized to mix a reconstituted tobacco material with the lamina.
Because of the decreased tobacco fibre size within the reconstituted tobacco materials, publicity to the same therapies as tobacco lamina might degrade, to some extent, the reconstituted tobacco. By method of instance, during drying, the moisture content of reconstituted tobacco is tremendously reduced, resulting in shrinkage of the tobacco particles forming the reconstituted tobacco sheet. Additionally, the cutting techniques typically employed to transform the tobacco materials mix into filler might end in some lamination and compression of the reconstituted tobacco material. All this causes a discount in the filling energy of the handled reconstituted tobacco and, accordingly, of the tobacco cut filler as a complete. A mode of a discrete probability distribution, as is the case with the minimize size distribution among the cut strips of the first tobacco material is a worth at which the chance mass function takes a maximum value. Thus, in a unimodal distribution, the likelihood mass operate solely has one maximum worth, and that corresponds to the most probably value of cut length .
In some embodiment, the reduce width distribution among the many reduce strips of the first tobacco material is preferably unimodal. In other embodiments, the cut width distribution among the cut strips of the primary tobacco materials may be multimodal, including specifically bimodal and trimodal. If a distribution has two or more modes, it is usually referred to as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the primary tobacco materials is shredded into strips having a minimize width of at least about zero.2 mm.
