Figures 1 to 12 reveals cut strips of a first tobacco material for incorporation in a cut filler according to 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 reduce specification, whereby the primary minimize specification sets a predetermined first minimize width CW1 and a predetermined first cut length CL1 . In addition, the primary minimize specification may further set a predetermined first sectional cut width SCW1.
In some embodiment, the reduce width distribution among the many cut strips of the primary tobacco material is ideally unimodal. In other embodiments, the minimize width distribution among the cut strips of the first tobacco materials may be multimodal, together with specifically bimodal and trimodal. If a distribution has two or extra modes, it is generally known as multimodal. Particular examples are bimodal and trimodal distributions, which have two and three modes, respectively. Preferably, the first tobacco materials is shredded into strips having a minimize width of no much less than about 0.2 mm.
Where OV is the actual % oven volatiles of the sample of tobacco reduce filler and f is a correction issue (0.four for the check indicated). In RYO, the stem can either be separated from the lamina by hand (for hand-stripped tobacco) or the stem and lamina aren’t separated in any respect (loose-leaf tobacco) – this form is used for Scandinavian Tobacco Group’s Norwegian RYO model Tiedemanns. A technique in accordance with any considered one of claims 15 to twenty, further comprising adjusting the moisture content material of the second tobacco materials. A fishbone-shaped strip is proven in Figure 6, whereas Figures 7 and eight present two embodiments of rectangular strips. Abstract The quantity of tobacco which is necessary for the proper filling of a cigarette depends on various factors and significantly on the filling weight of tobacco rag at a given strain. Some years ago the ”Centre d’Essais” of the SEITA developed an apparatus by which the filling weight being associated to the filling capability can be measured.
A tobacco minimize filler based on any one of the previous claims, wherein the primary tobacco material is a reconstituted tobacco sheet. Preferably, the cut filler has a filling power of a minimum of about 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles. More preferably, the minimize Filling cut tobacco filler has a filling energy of at least about 4 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. In addition, or in its place, 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 percent oven volatiles.
The shredding device is configured to cut the reconstituted tobacco in accordance to a primary minimize specification, whereby each minimize width and cut length are predetermined. The cut strips are dropped onto a conveyor belt 38 arranged beneath the shredding gadget 36 and defining a collection floor upon which the cut strips fall out of the shredding system. Additional means T may be supplied for tensioning the online of reconstituted tobacco as it’s tobacco pipe unwound off the bobbin. Further, the equipment 30 may comprise sensors forty for detecting the moisture content of the web of reconstituted tobacco upstream of the shredding device 36. In addition, the apparatus 30 may comprise mass circulate controllers forty two, 44 adapted to regulate the speed at which the net of reconstituted tobacco is fed to the shredding system 36 and the velocity of the conveyor belt 38.
Before each measurement was taken, tobacco particles cut in accordance with the various minimize specifications were saved in a conditioned room for 24 hours. For every specification, three measurements of the CCV were taken on the five samples, and then the entire common was calculated and assumed because the efficient CCV of the specification. Between repetitions of the measurements, the samples have been ready by detangling the individual strands, in order that any compaction occurred during the previous measurement would have as little influence as attainable on the subsequently measured CCV. In some embodiment, the cut size distribution among the many minimize strips of the first tobacco materials is preferably unimodal.
In specific, one such strip might comprise no less than a first strip structure comprising a branching node from which an extra strip construction branches off, forming an angle with the primary strip construction. The moisture content of the tobacco reduce filler is expressed herein as “percent oven volatiles”, which is determined by measuring the share weight loss from the minimize filler upon drying the fabric in an oven at 103 levels Centigrade (°C) for a hundred minutes. It is assumed that a significant majority of the weight loss from the cut filler outcomes from the evaporation of moisture. A technique in accordance with any certainly one of claims 15 to 17, wherein the second tobacco material is a reconstituted tobacco sheet.
The current paper describes the apparatus and its working situations and deals with the causes of errors by which the measurements could be influenced. Oriental leaves are 2 – 15 cm long and lightweight golden to dark orange in colour. The plant is grown in nutrient-deficient soil in a hot and dry climate, producing leaves containing a high level of fragrant oils. Quality checks are performed and the moisture of the tobacco is dropped at a degree that makes it secure for shipping to tobacco-manufacturing sites. American blend Typically a mixture of Virginia, Burley and Oriental tobaccos.
Experiments have been carried out so as to assess the impression of various shapes and minimize specs to key parameters of tobacco cut filler particles, such as the filling energy. In extra element, Figure 1 shows a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- shaped, it’s possible to measure a wave size of the reduce strip, which substantially corresponds to the strip cut length divided by the number of repetitions of the zigzag or wave. For occasion Fashion tobacco pipe, in the cut strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave size 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 preferably from four mm to 10 mm. Preferably, the tobacco minimize filler additional contains a second tobacco material reduce in accordance with a second cut specification differing from the first minimize specification for at least one of reduce length and cut width.
By means of example, it is recognized to provide tobacco reduce filler comprising minimize rolled stems having a predetermined rolled thickness and cut to a predetermined width. In order to enhance the taste and burning characteristics of the tobacco stem for use in the reduce filler, the stems are sometimes first subjected to a quantity of treatment procedures. In addition, or instead, it is known to mix a reconstituted tobacco materials with the lamina.
