Seeds are then air-screened, to remove chaff and inert material, using a Clipper Eclipse, Model 324, with a top screen: 1/16 round, 2nd screen: 1/18 round and a bottom screen: blank, medium to high air, (screen size and air can vary by lot). Seed lot is finished, using an Oliver Model 30, Gravity Separator, Speed: 50, Air: 50, Hopper speed: 1.5 (speed, air, and hopper speed vary by lot). This final process removes remaining nonviable seed and inert material.
