The smaller the seed, the more adjustment the process requires. Lar

First the seeds are poured through an opening into a chamber with a fan. The higher-density seeds fall into a compartment below, while the fan blows the lighter chaff and immature seeds out of the chamber and into separate bins to be discarded. We repeat this process several times to separate out as much of the chaff and immature seeds as po
