An improved apparatus for cleaning, distributing and aereating grain is mounted in a storage structure and includes a frustro-conical screen device secured symetrically to an imperforate funnel-shaped member. A fan assembly is secured to the funnel-shaped body and is provided with a conduit which extends to the exterior. An adjustable control spout permits uniform distribution of grain upon the screen device where the fine material passes through the apertures in the screen while the grain is discharged into the storage structure. After the cleaning and distribution of steps are completed, the apparatus will then be inverted to position the screen device in the concave crater of the grain pile while positioning the funnel shaped body and fan assembly uppermost. The fan assembly will be energized to aereate the grain and present damage due to mold or fungus.
