Abstract
A substantially horizontal grating having a plurality of substantially parallel bars extends within an enclosure that is adapted to gravitationally receive a mass of tobacco containing a cryogen and discharge smaller tobacco particles therefrom. A plurality of rotatable shafts having a plurality of blades equally separated by spacers are disposed orthogonally over the parallel bars such that the blades are located between the parallel bars. The spacers on the shafts and the parallel bars cooperate to define a plurality of sized apertures through the grating. The blades are formed to separate portions of the mass upon rotation and to urge the portions through the sized apertures for discharge from the apparatus.
