<p>In this manner an optimally configured conditioning gas stream can be mixed and distributed evenly over the maximum surface area of a slice of unconditioned tobacco in a conditioning cylinder. The gas stream consists of a mixture of air, steam, water droplets or other absorbable fluids required to bring the tobacco to the desired condition in the cylinder. An apparatus for conditioning tobacco comprises a cylinder conditioner (10) mounted for rotation about a generally horizontal axis, and an opening unit (12) mounted at the inlet end of the cylinder for rotation therewith, said opening unit having pins (14) projecting towards the axis of rotation for supporting portions of un-opened layers of tobacco e.g. bale slices (S), within the unit on initial entry thereof, and for effecting opening of the tobacco on rotation of the unit, the distal ends of the tines defining a frustoconical section which narrows in the direction of tobacco feed.</p> |
