Rough-winnowing chard seed to remove sticks and light/immature seed.  The hopper agitator prevents sticks and large debris from blocking the hopper opening, and is generally not necessary if seed is screened and field-winnowed first.

Following this step, I will pour the stick-and-chaff-free heavy fraction back through with a slower feed rate, a narrower feed slot, and a closer-in splitter setting – to remove unfilled-but-full-size seeds.  The Winnow Wizard can raise low-germ seed lots up to 90+% by removing lighter unfilled or immature seeds.
