The yield of flat rolled stem which may be used immediately as filler is elevated, and the common stem length and thus the typical length of minimize filler from stem is elevated. A tobacco reduce filler based on any one of many previous claims having a filling energy of a minimum of three.5 cubic centimetres per gram at a reference moisture worth tobacco pipe of 12.5 percent oven volatiles. Accordingly, tobacco particles were prepared from the same sheet of reconstituted tobacco in accordance with the minimize specification illustrated in Figure 12, wherein the cut width SCW1 is of zero.9 millimetres, the reduce length CL1 is of 4.94 millimetres and the worldwide width CW1 is of 12.50 millimetres.
More preferably, the primary tobacco material is shredded into strips having a minimize width of a minimal of about 0.25 mm. Even extra ideally, the primary tobacco materials is shredded into strips having a reduce width of no less than about zero.3 mm. In addition, or instead, the primary tobacco materials is preferably shredded into strips having a minimize width of lower than about 1 mm.
Sensors forty and mass move controllers forty two, 44, if present, are operatively related with a management unit forty six configured to control the operation of the apparatus. In particular, the control unit 46 adjusts the velocity to the conveyor belt 38 in view of variations within the velocity at which the web of reconstituted tobacco is fed to the shredding device 36, so as to prevent any undesirable accumulation of reduce strips on the conveyor belt. By finely controlling the scale and form of the strips into which the primary tobacco material is reduce or shredded, the features of the primary tobacco materials can advantageously be higher preserved whenever the first tobacco materials is mixed, in the shredded state, with another tobacco material. This is particularly advantageous when the first tobacco materials is a pre-processed tobacco materials, corresponding to a reconstituted tobacco sheet materials. The “thickness” of a minimize strip of tobacco material for incorporation in cut fillers in accordance with the current invention refers back to the distance between an upper surface and a decrease floor of the portion of fabric forming the cut strip.
Suitable natural tobacco leaf supplies include tobacco lamina, tobacco stem materials and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco material may embrace any kind of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco cut filler based on the present invention comprises a primary tobacco material reduce in accordance with a first minimize specification, wherein the first cut specification sets a minimum of predetermined first minimize width and first cut length. The term “filling power” is used to describe the amount of house taken up by a given weight or mass of a tobacco materials. The greater the filling energy of a tobacco materials, the decrease the burden of the material required to fill a tobacco rod of ordinary dimensions.
Alternative strategies for the manufacture of reconstituted tobacco sheets are also identified to the expert individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to check with an internet, preferably with considerably uniform thickness, which may be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by certainly one of several methods identified in the artwork. Suitable by-products include tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced through the manufacturing course of.
A tobacco reduce filler based on any one of the preceding claims, whereby the first tobacco material is shredded into strips having a reduce size from about 5 mm to about 60 mm. A tobacco minimize filler in accordance with any one of claims 2 to four, whereby the second tobacco material is a natural tobacco leaf materials. An angle of 90 levels was thought of to be undesirable, in that it will lead basically to a shape fairly similar to the shape of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the strategy preferably contains the step of mixing the reduce first tobacco material and the cut second tobacco materials.
In some embodiments, tobacco reduce filler according to the invention could also be used within the tobacco rod of a flamable smoking article, similar to a filter cigarette, cigarillo or cigar. Alternatively, the cut filler could also be used to provide the tobacco aerosol producing substrate in a distillation primarily based smoking article, or an electrically heated smoking system. Alternatively, the cut filler may be used as a roll-your-own or make-your-own product, or free tobacco product for use in a pipe.
