For food processors that generate wet oat hulls, the Dupps Ring Dryer turns what was once waste into usable bran meal that can be milled into oat bran flour.

Plants that produce fuel alcohol from corn use this high-efficiency dryer to turn spent mash into distiller's dried grain, which is sold as an animal feed ingredient. The Dupps Ring Dryer reduces the moisture content from 60% to 10% almost instantly, and recovers nearly half of the energy needed for drying from otherwise wasted exhaust heat.
