Grain flow paths (16) have an upper portion (17) which is a mixed flow portion and which includes a preheat zone and a lower portion (19) which is an undulating moisture equalizer portion and which includes a heat zone. Mixed flow grain diverters (88) extend across the grain flow path (16) substantially perpendicular to longitudinal side walls (95), and substantially parallel to transverse end walls (94) of the grain flow path (16). Upper airflow openings (89) are associated with each of the upper diverters (88). Moisture equalizer lower grain diverters (98) extend along the longitudinal sides (95) of the grain flow path (16) substantially parallel to the longitudinal side walls (95), and substantially perpendicular to the transverse end walls (94) of the grain flow path (16). The burner (12) is positioned outside the airflow path (16) to feed ambient air into the recirculating airflow path, without recirculating airflow passing through the burner (12). |
