The AT Ferrell Office Tester is a tabletop seed cleaner used for small lot specialized cleaning, grading, and sizing. The Office Tester’s shoe uses two 10″ x 15″ screens, one for the top and the other for the lower separation area.

The commodity is fed to the hopper and is spread evenly across the full width of the top screen. The product then moves across the top screen, which has openings larger than the product itself. The large foreign material is “scalped” off while the good product falls through the screen.

The bottom screen can either sift or scalp. For sifting, the bottom screen openings must be smaller than the commodity being cleaned. Trash, weed seeds and splits drop through the bottom screen while the good product passes over it. For scalping, the screen openings must be larger than the product itself. The large foreign material is “scalped” off while the good product falls through the screen.

The product is then routed through a column of air from the bottom blast fan which removes any lightweight trash and dust that may have remained after screening.

Good, clean product is discharged at the bottom of the air chamber into a clean seed box.
