ABSTRACT OF THE DISCLOSURE An improved grain drying apparatus of the type having a bin with a perforated floor through which hot air is blown upward for grain drying purposes, and a rotary sweep assembly employing a wet grain distributing auger on its lag side and a dried grain re- trieving auger on its lead side. One improvement includes an inclin- ed elongate plate forming an overflow dam which extends along the floor on the lead side of the retrieving auger and which is connected to the sweep assembly for rotation therewith so as to build up the thick- ness of dried grain on the floor ahead of the retrieving auger to in- crease the resistance of the dried grain to the upward flow of hot air on the lead side such that a greater proportion of hot air will flow upwardly through the floor on the lag side through the wet grain being deposited thereon. Additional features include provision for connect- ing the suction system of the apparatus to the wet lag side of the bin as well as to a central well into which the retrieving auger deposits dried grain for removal from the bin, and a system for recycling air suctioned from the bin through an external cyclone dust separator back into a plenum chamber under the perforated floor. - 1 -
