Abstract
Abstract A control system for grain drying bins of the type adapted to receive wet grain, remove moisture from the grain by the passage of heated air therethrough, and discharge dried grain. A portion of the heated air passing through the grain in the bin escapes through the grain discharge means, and the humidity of this escaping air is indicative of the moisture content of the grain being discharged. A humidity measuring device capable of controlling the on-off operation of the grain discharge means is located near the dried grain discharge outlet and is set to cause the discharge means to operate when the humidity of the air passing it is below a preselected level.
