ABSTRACT:
Intermixed light leaf and heavy stem tobacco particles are fed or propelled inwardly and across a vertical separator chamber of the classifier while forced air is directed upwardly through the intermixed particles and at varying velocities across the length of the separator chamber to gently separate the leaf particles from the heavier stem particles. The stream of intermixed particles is projected across the separator chamber at a variable initial velocity and the varying velocities of the upwardly directed forced air streams are correlated with the velocity of the stream of particles being fed across the separator chamber to gently separate the light leaf particles from the heavier stem particles. An adjustable deflector plate is supported adjacent the inlet feed for varying the angular position of the feeding of the stream of intermixed particles across the separator chamber to thereby vary the classifying plane in which the particles are projected across the separator chamber. A set of air pattern screens, with openings of different sizes therein, is provided for easy insertion and removal of the individual air pattern screens in the separator chamber to control the amount of forced air which passes upwardly through the separator chamber.
