Without wishing to be bound to concept, it will be appreciated that in any slicing, 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 “minimize length” of a reduce strip of tobacco materials for incorporation in minimize fillers based on the present invention could therefore be measured along the main course of fibre alignment, which typically corresponds to the longitudinal course. Thus, the minimize tobacco pipe size of an individual reduce strip can be precisely measured utilizing a traditional measuring gadget beneath a microscope. In a conventional course of, reconstituted tobacco or tobacco stem material or both are typically blended with threshed tobacco lamina to bear a series of remedies, corresponding to conditioning and drying. To this purpose, a reconstituted tobacco sheet is often ripped into randomly shaped sheet-like items having a non-uniform measurement, generally of several sq. centimetres.
Before every measurement was taken, tobacco particles minimize in accordance with the varied reduce specs were stored in a conditioned room for twenty-four hours. For each specification, three measurements of the CCV had been taken on the five samples, after which the total average was calculated and assumed because the efficient CCV of the specification. Between repetitions of the measurements, the samples had been ready by detangling the individual strands, in order that any compaction occurred during the earlier measurement would have as little affect as possible on the subsequently measured CCV. In some embodiment, the cut length distribution among the minimize strips of the first tobacco material is ideally unimodal.
The shredding device is configured to chop the reconstituted tobacco in accordance to a primary reduce specification, whereby each reduce width and reduce size are predetermined. The reduce strips are dropped onto a conveyor belt 38 organized beneath the shredding device 36 and defining a collection surface upon which the cut strips fall out of the shredding system. Additional means T could also be offered for tensioning the net of reconstituted tobacco as it Filling cut tobacco is unwound off the bobbin. Further, the apparatus 30 could comprise sensors 40 for detecting the moisture content of the net of reconstituted tobacco upstream of the shredding gadget 36. In addition, the equipment 30 may comprise mass move controllers forty two, 44 tailored to adjust the velocity at which the web of reconstituted tobacco is fed to the shredding gadget 36 and the velocity of the conveyor belt 38.
Flowers and higher leaves are eliminated to encourage the remaining leaves to grow.
In explicit, one such strip might comprise at least a first strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the first strip structure. The moisture content material of the tobacco reduce filler is expressed herein as “% oven volatiles”, which is decided by measuring the percentage weight reduction from the minimize filler upon drying the material in an oven at 103 levels Centigrade (°C) for one hundred minutes. It is assumed that a significant majority of the weight loss from the cut filler results from the evaporation of moisture. A methodology based on any certainly one of claims 15 to 17, whereby the second tobacco materials is a reconstituted tobacco sheet.
These irregular items are meant to be comparable in dimension to tobacco lamina, such that they are often blended with the tobacco lamina and cut. In explicit, the blend is usually reduce into particles having a predetermined reduce width. However, as a end result of the reconstituted tobacco sheet is somewhat randomly ripped into pieces, the tobacco fibres are generally not aligned in a uniform path. Tobacco rods have been prepared from a tobacco minimize filler using tobacco particles cut in accordance with the specifications of Figures 1 1 and 12. In particular, a first couple of blends had been used, that contained eighty five % by weight of natural tobacco particles and 15 % by weight of reconstituted tobacco particles reduce in accordance with specifications of Figures 1 1 and 12, respectively.
In other embodiments, the minimize length distribution among the cut strips of the first tobacco material may be multimodal, including in particular bimodal and trimodal. The “reduce length” of a strip of cut tobacco materials for incorporation in reduce fillers based on the present invention refers back to the maximum dimension of the strip of the tobacco material ensuing from the cutting operation, that’s the maximum measurable distance between two factors on the reduce strip. When looking at a reduce strip beneath a microscope, it’s going to typically be attainable to observe the course along which the minimize strip extends over such greater size .
Figures 1 to 12 shows cut strips of a primary tobacco materials for incorporation in a cut filler in accordance with the present invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a first reduce specification, wherein the first reduce specification units a predetermined first minimize width CW1 and a predetermined first reduce length CL1 . In addition, the first reduce specification could further set a predetermined first sectional reduce width SCW1.
A tobacco reduce filler in accordance with any one of many previous claims, whereby the primary tobacco materials is a reconstituted tobacco sheet. Preferably, the minimize filler has a filling power of no much less than about 3.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. More ideally, the reduce filler has a filling energy of at least about 4 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. In addition, or as an alternative, the cut filler ideally has a filling energy of lower than about 8 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles.
The expressions “final cut width” and “final reduce size” are used herein to explain the minimize width and cut size of a tobacco material as present in a tobacco minimize filler utilized in a tobacco product. The methodology could further comprise a step of conditioning the primary tobacco materials previous to slicing the first tobacco material. Further, the method might comprise a step of controlling the moisture content of the cut filler by adjusting the moisture content material of the first tobacco materials.
