Woodward Chaffy Seed Classifier 2000: Harvested seed is placed
in hopper (top) and metered to preconditioning chamber (black
cylinder, left). After fuzzy appendages are removed, seed moves
in air stream to classifier unit (atop preconditioning chamber).
As seed exits classifier it is separated into quality seed

Invention Streamlines Cleaning of Chaffy Seed By Luis March 14,
2003 A seed cleaner that smoothly conditions and separates some
of the toughest seeds to harvest has been invented by an
Agricultural Research Service scientist in conjunction with
private industry. The invention, named the Woodward Chaffy Seed
Classifier 2000, is a three-phase apparatus that meters,
preconditions and classifies seed. It was developed by the late
Chester L. Dewald, formerly a research agronomist at the ARS
Southern Plains Range Research Station in Woodward, Okla., and
Victor A. Beisel, an agricultural engineer with Aaron's
Engineering, a private firm based in Farg
