By way of example, tobacco stems may be ground to a nice powder and then blended with tobacco dust, guar gum, and water to form an aqueous slurry. This aqueous slurry may be forged and dried to kind a reconstituted tobacco sheet. As an alternative, appropriate tobacco materials may be combined in an agitated tank with water to acquire a pulp. This internet is fed onwards to a press, where the surplus water is squeezed out of the online. Figure thirteen illustrates an equipment 30 for the manufacture of a tobacco cut filler in accordance with the current invention. A web 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding system 36.
The shredding system is configured to chop the reconstituted tobacco in accordance to a primary minimize specification, whereby both reduce width and reduce length are predetermined. The minimize strips are dropped onto a conveyor belt 38 organized beneath the shredding gadget 36 and defining a set floor upon which the minimize strips fall out of the shredding device. Additional means T may be supplied for tensioning the web of reconstituted tobacco as it’s unwound off the bobbin. Further, the apparatus 30 may comprise sensors 40 for detecting the moisture content of the online of reconstituted tobacco upstream of the shredding device 36. In addition, the apparatus 30 could comprise mass circulate controllers forty two, 44 adapted to regulate the speed at which the online of reconstituted tobacco is fed to the shredding gadget 36 and the speed of the conveyor belt 38.
For instance, a bimodal distribution may correspond effectively to 2 teams of cut strips having totally different common minimize lengths , one group being bigger than the other. Preferably, the first tobacco material is shredded into strips from a sheet material having a thickness of at least about 0.05 mm. More ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about zero.1 mm.
According to a side of the present invention, there could be supplied a tobacco reduce filler comprising a primary tobacco materials minimize in accordance with a first cut specification, whereby the primary cut specification sets no much less than predetermined first reduce width and first minimize length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for getting ready tobacco stem to be Filling cut tobacco used as filler for a smoking article includes classifying the green tobacco stem by diameter to supply a plurality of stem grades and rolling every grade separately. Each grade is rolled under rolling circumstances optimized for that grade including rolling the grade through the nip between rollers with the nip measurement being adjusted for each grade so as to attain a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted earlier than the rolling.
In addition, the formation of tobacco dust is reduced compared with conventional manufacturing methods. Accordingly, the necessity to acquire and re-process tobacco dust is considerably lowered and the overall efficiency of the manufacturing process is thus advantageously increased. A tobacco reduce filler according to any one of many preceding claims, wherein the primary tobacco material is shredded into strips having a sinusoidal form Fashion tobacco pipe, whereby a wave length of the sinusoidal form is from about 1 mm to about 15 mm. A tobacco minimize filler in accordance with any one of many preceding claims, whereby the primary tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Table 2 below lists the values of CCV measured at a reference moisture worth of 12.5 percent oven volatiles for each pattern.
