ABSTRACT:
The present invention relates to a method and apparatus for drying particulate materials such as seeds and grains in which an air dryer having a shape of a vertical, cylinder and at least one drying stage with a mesh screen disposed therein with a horizontal mesh screen. An upwardly vertical air flow having a velocity in the mesh openings at least equal or larger than to the suspension speed of the particles to be dried temporarily suspends the particles until enough accumulate to provide sufficient weight or downward pressure for the particles to overcome the upward air flow, pass downward through one or more mesh screens and reach the bottom of the dryer.
