Definitions

  • This invention relates to tobacco threshing.
  • a known form of tobacco thresher is described in our US-A-4077573 and comprises a plurality of rotors provided with cutting teeth and mounted on a common shaft, a housing having an arcuate surface surrounding part of the rotors and an entry opening for tobacco leaves, openings (e.g., a screen) surrounding another part of the rotorfor discharge of portions of laminae cut from the tobacco stems, and two sets of fixed cutters parallel with the shaft and offset 180° to each other and- co-operating with the rotor cutting teeth for threshing the tobacco.
  • the rotating teeth have a small clearance from the inside of the housing and are arranged to interleave the two rows of fixed teeth.
  • the moving teeth, the fixed teeth and the screens all contribute to the cutting or removal of the lamina from the mid-rib of the tobacco leaf.
  • the diameter of the drum over the rotating teeth is typically 26" (66 cm) and the rotational speed 500 to 600 giving a tooth tip speed of 3,400 to 4,000 fpm., (1036 to 1219 metres per minute).
  • An object of this invention to increase the size of lamina produced by the thresher, in order to increase the strand length when the lamina is cut and hence the fillling power in the cigarette.
  • Another object of the invention to increase the throughput capacity of a given size of thresher.
  • a tobacco thresher having a plurality of rotors mounted on a common shaft, and provided with cutting teeth, which teeth are arranged to coact with fixed cutters, a housing having an arcuate surface surrounding part of the rotors, an entry opening for tobacco leaves, a screen surrounding another part of the rotor having openings for discharge of portions of laminae cut from the tobacco stems, characterized in that only one set of fixed cutters is disposed parallel to the shaft and is located at the end of said screen remote from said entry opening, and in that a discharge means is provided between the fixed cutters and the adjacent end of the arcuate surface of the housing, whereby the tobacco leaves are first threshed between the cutting teeth and the openings of the screen followed by cutting between the cutting teeth and the fixed cutters.
  • Said entry opening and said discharge means may each extend over approximately 90° of said rotor, said fixed cutters being offset approximately 90° from the adjacent end of said arcuate surface.
  • the entry opening may be near the top of the rotor and the fixed cutters may be at the bottom of the rotor.
  • a curved or inclined discharge surface may be provided adjacent said adjacent end of the arcuate surface, said inclined surface being arranged to direct tobacco from the tangential direction as it leaves the fixed cutters to a downwards direction with a curved discharge surface.
  • the length of the screen may extend over an angle of up to 180°.
  • An apparatus for threshing may comprise a plurality of threshers and pneumatic means for separating fine tobacco from the stems between each adjacent pair of threshers, the stems being passed through the next thresher and so on, the aperture size in the screens being less in each succeeding thresher.
  • a shaft 10 carries a series of rotors 11 which are provided with cutting teeth 12.
  • the rotors may be spaced every 5 cm over the width of the thresher which is preferably 1 m wide. In all about 18 rotors may be provided.
  • a housing 14 has an entry opening 13 near the top of the rotor and has an arcuate surface 16 concentric with the rotor surrounding approximately 90° of the rotor from the opening 13 in the direction counter to the rotation of the rotor.
  • Mounted in the housing at the bottom of the rotor is the single row of fixed cutters 18 offset approximately 90° to the adjacent end 19 of the arcuate surface 16.
  • a single screen 20 concentric with the rotor extends from the fixed cutters 18 through approximately 90° towards the opening 13. The fine portions of the laminae discharge through the screen as shown by the arrows 21 and the stems continue as shown by the arrows 22.
  • the leaf is first subjected to the action of the rotary teeth 12 and the screen 20 and leaf is removed and discharged with minimum reduction of size, before passing the fixed teeth 18 where greater breakage of leaf occurs. After passing the fixed teeth 18 the smaller portions of the tobacco leaf are discharged through the discharge opening 15.
  • the arcuate surface 16 is continued to within an angular space of about 40° from the cutters 18 and an inclined deflecting surface 25 extends from the end 26 of the arcuate surface downwards so as to direct the tobacco leaving the cutters downwardly and discharging completely.
  • the arrangement shown in Figure 3 is similar but the deflecting surface 27 is arcuate and the lower end 28 of the arcuate surface 16 is angularly offset by about 60° from the cutters 18.
  • the screen 20 may alternatively extend up to an angle of about 180° by shaping the adjoining surfaces of the lower end 28 of the arcuate surface 16 and the upper end of the deflecting surface 27 to a more acute angle.
  • a complete threshing process may consist of several successive stages of threshing, typically five, each followed by one or more stages of pneumatic separation.
  • the separation removes the "clean” lamina (without stem) and passes the "unclean” stem (with lamina still attached) on to the next stage of threshing.
  • the severity of the threshing action is inreased in succeeding stages.
  • the improved form of thresher is most effectively used in the less severe first and second stages of threshing, where the leaf particles are still large.
