Abstract: A relatively compact, streamlined dryer for use in hopper-bottomed grain bins includes a foraminous, cylindrical casing surrounding a foraminous, cylindrical duct, which is coaxial with the casing, the openings of the casing and duct being directed downwardly to reduce the risk of clogging; triangular brackets extending outwardly and downwardly from the casing for pivotally supporting feet so that the dryer can readily be mounted on the sloping floor of a bin over the central discharge opening thereof without substantially impeding the unloading of grain; an inlet duct in the side of the casing for admitting air into the dryer; and a frusto-conical, annular cap on the top end of the dryer closing the top of the passage between the casing and the duct.
