ABSTRACT:
A portable grain drying apparatus comprising a wheeled frame having a cylindrical housing mounted thereon and extending upwardly therefrom. The housing is provided with a perforated wall portion to permit the escape of air therethrough. An inverted conical-shaped perforated lower floor is provided in the housing above the lower end thereof. The lower floor is provided with a plurality of diamond-shaped air passageways positioned thereon around a centrally disposed grain discharge opening formed in the lower floor. The air passageways also define radially extending grain passageways therebetween to facilitate the even flow of the grain on the lower floor towards the grain discharge opening. A dryer blower is mounted on the lower end of the housing for supplying heated air under pressure to the lower interior of the housing below the perforated lower floor so that a portion of the air passes upwardly through the perforated lower floor and so that a portion of the air passes upwardly through the diamond-shaped air passageways. A perforated cylindrical wall member is positioned with the housing and is spaced therefrom and from the lower floor to provide grain passageways therebetween. The upper end of the cylindrical wall is provided with a conical-shaped member extending thereover for supporting grain thereon and for permitting the passage of air upwardly therethrough. A conveyor is mounted on the housing and has one end in communication with the grain discharge opening and its other end positioned outwardly of the housing.
