ABSTRACT:
Apparatus for separating lighter particles from tobacco particles contained in threshed leaf tobacco includes a plurality of tobacco particle separating units, each including a separation chamber and having a fan system for establishing a generally upward air flow therein. A tobacco particle projecting mechanism is provided in each chamber for projecting, in cooperation with additional air flow provided at the projecting side of the separation chamber, tobacco particles across the upward air flow therein with each having structure for directing tobacco particles in cooperating relation therewith to be projected thereby. Mechanisms receive the lighter particles carried upwardly by the air flow, the heavier particles moving downwardly within each chamber and discharge the particles therefrom. The tobacco particle separating units are mounted in side-by-side relation in a row which includes an initial end unit and a final end unit with the tobacco particle directing structure of the initial end unit arranged to receive a supply of threshed leaf tobacco and the tobacco particle directing structure of the remaining of the plurality of units being directly connected to receive tobacco particles through a tobacco particle opening in the receiving side of the chamber of the preceding unit so that the tobacco particles projected across the chamber of the preceding unit which move across the air flow therein and pass through the opening form a tobacco particle supply directed to an associated projecting mechanism by an associated tobacco particle directing structure.
