In most popular embodiments, the first tobacco material is a pre-processed tobacco material. By “pre-processed tobacco material” reference is made throughout the specification to a tobacco material produced by man from pure tobacco versus occurring naturally as such. It would due to this fact be fascinating to supply an alternative tobacco minimize filler having improved filling energy. At the identical time, it would be desirable to offer a novel process for manufacturing tobacco reduce filler, whereby the filling energy of the tobacco minimize filler is improved and the manufacturing of tobacco mud is lowered. The current invention relates to the production of tobacco minimize filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the cut filler based on the invention.
This doc specifies a method for determination of filling energy for preparation of fine-cut tobacco smoking articles. Its leaves are 20 – 50 cm lengthy and vary in color from gentle brown to very darkish brown. When the lowest leaves are harvested, the entire plant can both be reduce down and dried or the plant could be harvested leaf-by-leaf. A methodology according to any considered one of claims 15 to 18, additional comprising conditioning the first tobacco materials previous to chopping the primary tobacco material . A methodology based on claim 18, comprising controlling the moisture content of the minimize filler by adjusting the moisture content of the first tobacco material. A tobacco cut filler based on claim 1 , further comprising a second tobacco material cut in accordance with a second reduce specification differing from the primary minimize specification for at least one of cut length and minimize width.
By means of example, it’s known to supply tobacco reduce filler comprising minimize 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 for use in the cut filler, the stems are often first subjected to one or more remedy procedures. In addition, or as an alternative, it’s identified to mix a reconstituted tobacco material with the lamina.
As the name implies, it’s merely a combination of totally different tobacco types, cuts and flavors. They are easy to fill and smoke, and have higher robustness and style selection than free cut tobacco by itself. The first tobacco materials may be reduce into strips having any suitable form, together with rectangular, trapezoidal, sinusoidal, Y-shaped, X-shaped and V-shaped.
In follow, one such cut strip may be described as roughly wave-shaped or zigzag-shaped. Accordingly, geometric parameters comparable to the peak amplitude, peak-to-peak amplitude, period of a sine wave may be used to explain the shape of one such reduce strips. A tobacco reduce filler contains a primary tobacco materials minimize in accordance with a first minimize specification, wherein the primary minimize specification sets at least predetermined first minimize width and first minimize size. A tobacco reduce filler based on any one of the previous claims, whereby the first tobacco material is shredded into strips having a minimize width from about zero.2 mm to about 1 mm.
Without wishing to be bound to theory, will most likely be appreciated that during any cutting, rolling or extruding operation, the tobacco fibres typically align in a given path, which can thus be recognized because the longitudinal course of the tobacco materials. The “cut length” of a minimize strip of tobacco materials for incorporation in reduce fillers according to the present invention could therefore be measured alongside the primary course of fibre alignment, which generally corresponds to the longitudinal course. Thus, the reduce Fashion tobacco pipe size of an individual minimize strip may be precisely measured using a standard measuring system under a microscope. In a conventional process, reconstituted tobacco or tobacco stem materials or both are usually blended with threshed tobacco lamina to bear a series of therapies, such as conditioning and drying. To this function, a reconstituted tobacco sheet is often ripped into randomly formed sheet-like items having a non-uniform measurement, generally of a quantity of square centimetres.
In the embodiment of Figure 10, the 2 straight components are considerably perpendicular. The cut strip of Figure 12 may be regarded as comprising three V-shaped structures of the sort illustrated in Figure 1 , wherein adjacent V-shaped buildings are connected by the ends of respective straight parts. In the embodiments of both Figures 10 and 12 the sectional cut width inside all of the structures forming the reduce strips is substantially constant. A tobacco cut filler according to any one of the previous claims, whereby the minimize length distribution among the reduce strips of the first tobacco materials is ideally unimodal. By method of instance, the reduce strip of Figure 9 includes a first Y-shaped construction together with a first branching node from which a second Y-shaped structure branches off.
In some embodiment, the cut width distribution among the many reduce strips of the first tobacco material is preferably unimodal. In different embodiments, the minimize width distribution among the cut strips of the primary tobacco materials may be multimodal, including in particular bimodal and trimodal. If a distribution has two or more modes, it is generally referred to as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the primary tobacco material is shredded into strips having a cut width of at least about zero.2 mm.
The expressions “final reduce width” and “final minimize length” are used herein to describe the reduce width and reduce length of a tobacco material as found in a tobacco reduce filler utilized in a tobacco product. The methodology could additional comprise a step of conditioning the first tobacco materials previous to slicing the first tobacco materials. Further, the tactic might comprise a step of controlling the moisture content of the reduce filler by adjusting the moisture content of the first tobacco materials.
