PCT No. PCT/AU96/00745 Sec. 371 Date Jul. 24, 1998 Sec. 102(e) Date Jul. 24, 1998 PCT Filed Nov. 22, 1996 PCT Pub. No. WO97/18721 PCT Pub. Date May 29, 1997An apparatus for separating outer layers or shells from the internal seed of plant matter comprises a plant matter inlet (12), a seed outlet (14) and a generally vertical separating chamber (16) interposed between the inlet and outlet. The separating chamber is cylindrical and includes a plurality of axially spaced apart inwardly facing nozzles (18) and a plurality of spaced apart apertures (20). The apertures are a size smaller than the seeds being separated to allow only the outer layer or shells to pass therethrough. A separating chamber includes a plurality of inclined to horizontal baffles (21) to increase the residence time in the plant matter in the chamber.
