Definitions

  • the invention relates to a method for separating tobacco parts consisting of tobacco rib pieces (rib pieces) from tobacco parts which consist of tobacco fibers (leaf fibers and rib fibers) which are glued, folded or clumped together.
  • the invention also relates to an arrangement for separating tobacco parts consisting of tobacco rib pieces (rib pieces) from tobacco parts which consist of tobacco fibers (leaf fibers and rib fibers) which are glued, folded and clumped together.
  • tobacco leaves are first stripped and the largely rib-free tobacco leaf parts are cut into tobacco fibers (leaf fibers) after adding flavorings, the so-called sauce.
  • the largely leaf-free tobacco rib parts are treated separately and also cut into fibers (rib fibers).
  • the two tobacco fiber components are then mixed together and processed into cigarettes in cigarette machines.
  • the tobacco parts described above in particular from the ribs of the tobacco plant, the rib fibers, there are rib pieces which have a relatively high specific gravity (weight / air resistance) and, because of the associated rigidity, hinder cigarette production. Such rib pieces are therefore often made of the specifically lighter rib fibers and the light ones.
  • Leaf fibers separated e.g. B.
  • this is achieved in that the intermingled rib pieces and tobacco fibers are heated by passing on steam, the tobacco fibers which are glued, clumped or folded together being essentially detached and opened from one another, and in that the rib pieces and the loosened and opened tobacco fibers are subsequently opened undergo a screening process in which the ribs are separated from the tobacco fibers.
  • the relative humidity of the tobacco is increased when saturated steam or superheated superheated steam is passed on. According to the invention, this increase in the relative humidity lies in a range between 2% and 10%, whereby warm water can also be sprayed on to achieve high relative humidity values. If necessary, it can also be damped in several stages.
  • the condition of the steam conducted onto a 12% to 13% moist Winnover tobacco is chosen according to a development of the invention so that a relative low dampening of the tobacco fibers occurs, for example approx. 3%. If the relative initial moisture content of the tobacco fibers is lower or higher, the moisture level should be kept higher or lower if the final moisture content of the fibers should be approx. 13%.
  • the tobacco fibers according to the invention are to be damped at temperatures which are as high as possible and which do not yet impair taste.
  • the temperatures at the end of the damping can be between 70 ° C and 115 ° C.
  • a very good result with regard to the dissolving and the recovery of the still usable tobacco fibers is achieved without any taste impairments at a final temperature of the tobacco when steaming from 95 ° C. to 105 ° C., e.g. B. approx. 100 ° C.
  • a particularly suitable type of damping is that the tobacco fibers are dampened before being separated by supplying steam from the bottom of a vibratory conveyor that conveys the tobacco fibers.
  • Another possibility of damping is to guide the tobacco onto the tobacco fibers as they pass through a conveyor drum, such as is described in US Pat. No. 4,235,249.
  • the steamed, heated tobacco fibers can be conveyed very advantageously according to the invention on a conveyor line on which they can cool, for which purpose an oscillating conveyor line is particularly suitable.
  • the tobacco fibers can be sighted by a relative movement between air and tobacco fibers, that is to say by mechanical spinning of the tobacco fibers in still air, by flowing air or by spinning the tobacco fibers in flowing air. Heated visible air can be used here, especially with relatively moist tobacco fibers.
  • the arrangement mentioned at the outset is characterized by a damping device for guiding steam onto a mixture of ribs and tobacco fibers, which are thereby heated and swirled, the tobacco fibers which are glued, clumped or folded together being detached from one another and opened, and by a downstream viewing device for separating them the ribs from the loosened and opened tobacco fibers.
  • the advantage achieved with the invention is that those tobacco parts in the Winnover tobacco that are glued, folded or clumped tobacco fibers exist and previously had to be separated from further processing together with the unusable rib pieces, can be broken down and further processed, the quality of these tobacco fibers being good. The tobacco loss can thus be reduced.
  • the arrangement according to the invention essentially has a damping device 1, a conveyor section 2 and a viewing device 3.
  • the tobacco parts 4 fed to the damping device 1 form a mixture of a very small amount of light leaf fibers and relatively light rib fibers as well as the majority of heavy rib pieces and heavy tobacco particles, which consist of glued, clumped and folded leaf and rib fibers, of which the leaf fibers are usually the make up an oversized share.
  • the heavy, unusable rib pieces are to be separated from this mixture and the tobacco fibers glued together are to be disrupted, ie dissolved and made suitable for further processing.
  • the tobacco 4 is fed by means of a conveyor belt 6 to the damping device 1, which has a vibration conveyor 7.
  • the vibration conveyor 7 has a tunnel-shaped closed interior 8 and a bottom 9, in which channels in the form of bores 11 are made.
  • Steam supplied by a steam generator 13 and an elastic pipeline 14 can be conducted into the interior 8 through a steam box 12.
  • the steam emerges from the bores 11 in relatively highly concentrated jets 16 and swirls the tobacco particles 4 located in the interior 8 intensively, heating them and, depending on the steam condensation, humidifying them more or less.
  • the entire tunnel 17 is mounted on a frame 19 via leaf springs 18 and can be driven to vibrate by means of an eccentric drive 21, through which the tobacco particles 4 are conveyed through the tunnel 17 in the direction of the arrow 22.
  • the steam emitted by the steam generator 13 can be superheated steam if no or only a relatively small amount of humidification of the tobacco 4 is desired in order to e.g. B. at the end of the treatment again to obtain leaf and rib fibers of approximately processing moisture.
  • tobacco particles with a relative initial moisture between 12% and 13%) are moistened by about 3% during steaming.
  • the steam generator preferably emits saturated steam which moistens the tobacco particles (again based on their relative initial moisture between 12% and 13%) by approximately 5% to 6%. If the desired humidification is even higher, finely divided warm water is additionally sprayed into the interior 8 in a manner known per se.
  • the humidification can be correspondingly higher or lower. Mix-specific differences in dampening are also possible.
  • the steam is supplied from the steam generator 13 with increased pressure in order to achieve an intensive swirling of the tobacco particles in the interior 8. Pressures of 5 bar or more are advantageous for this. Pressures around 10 bar have proven to be particularly advantageous.
  • the steam condition and the length of the vibration conveyor 7 are matched to one another in such a way that the tobacco particles are strongly heated, e.g. B. to temperatures between 70 ° C and 115 ° C. An advantageous range is between 95 ° C and 105 ° C. During the conveyance by the vibration conveyor 7, the tobacco particles are heated and preferably moistened.
  • the glued-together, folded fibers are opened up and detach from one another or open what the intensive turbulence by the powerful steam jets 16 from the holes 11 in the bottom 9 contributes to.
  • the leaf and rib fibers together with the rib pieces leave the damping section in a heated and moistened state.
  • the tobacco particles then reach the conveyor section 2, which is designed as an open vibrating conveyor trough 26 and is mounted on a fixed frame 28 via leaf springs 27.
  • An eccentric drive 29 provides oscillatory movements for conveying the tobacco particles in the direction of arrow 22.
  • the tobacco particles are fed from the vibrating conveyor trough 26 to the entrance 36 of the viewing device 3.
  • the tobacco particles (according to arrow 37) are conveyed from a revolving cellular wheel sluice into a viewing space 38 through which an upward air flow (indicated by arrows 39) flows.
  • the heavier rib pieces sink down onto a sieve 41 which is inclined slightly downwards and which is driven by an oscillating drive to oscillate.
  • the rib pieces 4a thus slide down in the direction of arrow 43 and are discharged from the viewing device 3 at the first outlet 44.
  • the light fibers 4b which are detached and opened from each other, among which there can be relatively few specifically light ribs and leaf fibers already present in the mixture 4 supplied, are conveyed by the upward airstorm 39 to a sieve 46 acting as a separator, through which the visible air reaches the suction side of a fan 48 via a line 47.
  • the light tobacco fibers deposited on the sieve 46 that is to say in particular the loosened tobacco fibers, pass via a conventional cellular wheel sluice (not shown) to a conveyor belt 51 which conveys them to further processing.
  • the viewing device 3 can, if drying of the damped Tobacco is desirable to be supplied with heated air, z. B. from the pressure side of the fan 48 via a heating register, not shown, which heats the classifying air.
