Summary:A novel dry mill process for producing pure starch, which can be used as a feed stock for bio tech processes. Corn feedstock is sent through a particle size reduction device, such as a hammer mill, to produce corn flour. The corn flour is screened into a small particle portion (which mainly contains "free" starch from the floury endosperm) and a larger particle portion (which mainly comprises the horny endosperm, germ pericarp and tip cap). The small particle potion is sent to a liquefication and a saccharification process to produce high Be corn syrup. A mud phase (mixture of oil, germ, and any light solid) is centrifuged. The light phase is sent to precoat drum filtration to produce clean corn syrup. Further, a novel wet mill process to produce starch and alcohol is disclosed. A three-section paddle screen can be used to separate starch from grit and fiber.
