Typical Commodity Flow:
1.
The commodity is fed to the hopper and is spread evenly
across the full width of the top screen.
2. 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.
3.
The bottom screen can either sift or scalp. To set up 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. (This is the flow shown in the diagram). When
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.
4.
Next, the product is routed through a column of air from the
bottom blast fan. This blast of air effectively removes any
lightweight trash and dust that may have remained after
screening.
5.
Good, clean product is discharged at the bottom of the air
chamber into a clean seed box.
