ABSTRACT:
An apparatus for separating constituents of a mixture of dry organic material having different weights or densities, such as pine straw and lawn debris, includes a cylindrical housing that is positioned horizontally with respect to a working surface. The housing has a hopper on its top side, an inlet end and an outlet end, and a fan is mounted at the inlet end. The fan pulls air into the housing and generates a stream of air flow inside the housing from the inlet end to the outlet end thereof. An air baffle structure is located immediately downstream of the fan to produce substantial turbulence in the air flow stream. The mixture of material to be separated is introduced into the housing through the hopper and is then carried from the housing and separated into constituent parts by the stream of air flow. Higher density constituents are deposited at shorter distances from the housing outlet end while lower density constituents are deposited at a greater distance from the housing outlet.
