Abstract
A method and apparatus are disclosed for the separation and classification of tobacco into two fractions, e.g., into heavies and lights. A stream of fluid is employed to produce a stratified bed of the tobacco, preferably in cooperation with vibration of the tobacco, in which the tobacco is supported by the fluid and is stratified as a function of particle size, density and weight. The stream entrains the tobacco particles located at the top of the stratified bed and removes them to a suitable receptacle, where they are received and collected.
