The apparatus includes a chamber to contain the seed to be threshed. Mounted rotatively in the chamber is at least one filament spool means which, upon rotation, causes filament to be paid out and thresh the seed. Means are attached to the chamber to draw a gaseous medium through the chamber to suspend the seed with appendages in the threshing zone. After the appendages are removed, the appendage-free seed is discharged from the cylinder. The invention finds particular use in the threshing of seeds armed with appendages that are difficult or impossible to remove with existing seed threshing equipment.Other References
