    2014-7-1 · In the case of mixed-flow dryers (MFDs) air input is more uniform over the cross-section of the dryer, but the air inlets and the outlet structures disturb the uniformity of motion of the grain mass (Brooker, Hall, & Bakker-Arkema, 1992). The movement of grain cannot be considered to be one-dimensional and depends on the selected dryer geometry.
