The Red Giant Stir-Ator is a 4 or 6 auger-stirring machine designed for drying bins using high heat and large airflows. The extra augers provide the additional stirring required with high drying rates. The Red Giant uses a roller chain, positive drive system to move the trolley in and out as the Stir-Ator moves around the bin to generate the familiar DMC spiral stirring pattern. The trolley is designed so the augers in the center of the bin rotate slower than the augers at the bin wall to avoid over stirring the grain in the center of the bin. The gentle stirring at the center of the bin makes the Red Giant an excellent choice for drying rice. The Stir-Guard is a standard feature on the Red Giant.
