Abstract

A grain cleaner having a plurality of cleaning sections radiating outwardly from a grain inlet. Each cleaning section has upper and lower downwardly sloped screens over which grain flows by gravity to sift out fine foreign material. Upper and lower foreign material chambers underlie respective screens, and external bypass ducts bypass foreign material from each upper chamber to an associated lower chamber of each cleaning section. Each lower foreign material receiving chamber communicates with a centrally located foreign material discharge outlet at the bottom of the cleaner.
