The technology of in-bin and continuous-flow grain dryer controllers was assessed. In-bin controls are usually of the heuristic type. Control for continuous-flow grain dryers is of either the classical feedback or the adaptive feedforward type. Moisture-based control is recommended for large variations in moisture content. Several commercial controllers were evaluated. It was concluded that controllers have finite grain- quality and cost advantages when installed on in-bin and continuous-flow systems.
