ABSTRACT:
A continuous grain drying and conditioning apparatus of a type including a burner and blower, or a multiplicity of burners and blowers, surrounded by a plenum chamber, air pervious grain holding walls positioned outwardly with respect to the plenum chamber is characerized by having a plenum divider which is selectively adjustable in position to divide the grain holding walls into a heating section and a cooling section. Grain turning apparatus is disposed in the grain column for separating the grain mass into two separate divisions and then turning the cooler-wetter grain inwardly as it moves downwardly and turning the hotter-dryer grain outwardly as it moves downwardly in the grain column. Grain is constantly removed from the bottom of the apparatus at a rate governed by the average temperature of the air exiting the grain at a point adjacent the position of the plenum divider and a point closer to the input of the grain. Grain to be dried and conditioned is constantly introduced into the top of the apparatus as fast as dried and conditioned grain is delivered out of the bottom of the apparatus. Structure is also provided for recycling unsaturated exhaust air back through the dryer.
