ABSTRACT:
A process for drying grain in which the grain is first heated to drive off a portion of the moisture as it passes along a conveyor, and the heated and partially dried grain is then discharged into a holding or steeping bin where the moisture in the center of the kernels migrates to near the surface and the temperature becomes substantially uniform throughout. The grain is then discharged onto a second belt where the grain is first heated to drive off a substantial part of the moisture remaining in the grain and then is cooled before it is discharged from the apparatus. Air is used to cool the grain before it is discharged and this partially heated air is utilized in both grain heating operations.
