Definitions

  • the invention relates to a device for transferring tobacco parts into a current dryer through which gaseous and / or vaporous drying medium flows, with a lock arrangement and with a centrifugal agent in the region of the mouth opening.
  • Electricity dryers for tobacco are known in several embodiments. Of particular importance for a good drying effect is the way in which the tobacco is transferred to the current dryer, especially if an expansion effect is to occur in addition to the drying effect.
  • the object on which the invention is based is to create a further feed device for tobacco to a current dryer which is advantageous from the point of view of the homogeneity of the drying. In addition, if desired, a uniform and good expansion of the tobacco parts should take place.
  • Tobacco can be understood to mean pieces of tobacco or ribs of tobacco, cigar insert and tobacco fibers cut from tobacco or ribs for the manufacture of cigarettes.
  • the solution according to the invention is that the feed direction of the tobacco parts entering the current dryer runs obliquely to the flow direction of the drying medium.
  • Advantageous further developments and further refinements of the invention can be found in the subclaims.
  • the advantage of the device according to the invention is that the tobacco can be introduced well separated and evenly into the current dryer, which is important for uniform drying and good expansion of the tobacco. With the device according to the invention, tobacco products with very high initial moisture content of 20% to 50% can be handled without problems and be introduced into the current dryer without harmful compression or degradation.
  • a tubular current dryer 1 is arranged obliquely and of hot gas with or without steam, in particular hot air, or hot steam (superheated steam) from a temperature between 150 ° C and 600 ° C, in particular between 200 ° C and 400 ° C, for . B. 300 ° C, flows in the direction of arrows 2.
  • a cylindrical part 1a of the current dryer merges into a trough-shaped form 1c (FIG. 3) via a transition zone 1b and from there via a further transition zone 1d into a further tubular part 1e.
  • a centrifugal means 4 in the form of a centrifugal roller, the arms 6 of which, according to arrow 7, rotate about an axis 8 at a speed between 300 rpm and 1000 rpm rotate.
  • the feed surface 9 of a housing 11 surrounding the centrifugal roller 6 is shaped in such a way that the tobacco parts which have been thrown pass through the orifice 3 into the current dryer 1 approximately according to arrow 12.
  • the angle between the feed direction of the tobacco parts (arrow 12) and the flow direction of the drying medium (arrow 2) is approx. 45 °, but it can deviate upwards and downwards.
  • a half orifice 13 is provided, which leads to a drop in pressure at the mouth opening and constricts the flow of the drying medium so that deposits on the wall of the flow dryer 1 opposite the centrifugal roller 4 are avoided.
  • Another housing 16 is flanged over the housing 11, to which a cell wheel 18 rotating according to arrow 17 is fitted on the inside 19, so that the cell wheel 18 and the inside 19 of the housing 16 form a cellular wheel sluice 21, which separates the current dryer 1 from the atmosphere and allows the supply of tobacco parts to the current dryer in the direction of the arrow 22.
  • FIG. 4 shows the shape of an arm 6 of the centrifugal device 4 with a holding strip 6b and tines 6c attached thereto, which is particularly suitable for accelerating relatively long tobacco fibers cut from leaf tobacco.
  • FIG. 5 shows the shape of an arm 6 of the spinner 4 with a holding bar 6b and a sheet 6c attached to it, which is particularly suitable for accelerating shorter tobacco fibers cut from ribs and insert tobacco for cigars.
  • the current dryer 1 can also be arranged in a different position than the one shown, the position of the tobacco supply 4 to 22 then also changing accordingly.
  • FIG. 6 shows a current dryer 101, which is in particular provided with a tobacco supply 105 according to the invention and is arranged in a tobacco conditioning system.
  • the tobacco supply can be provided with a centrifugal roller 104 only indicated and a cellular wheel sluice 121 also only indicated, the details of which are shown in FIGS. 1 to 5.
  • Upstream of the current dryer 101 is a dampening device in the form of a moisture conveyor 126, as is shown in detail in US Pat. No. 4,766,912.
  • the moisture conveyor 126 is therefore a vibratory conveyor designed as a closed tunnel, the input 127 of which is fed to tobacco in accordance with arrow 128.
  • Live steam can be fed into the circuit according to arrow 143 via line 141 and valve 142.
