ABSTRACT:
The present invention provides a seed dryer having an air kettle. The air kettle defines a seedbed. A plenum and diffuser direct air from an air supply to the bottom of the seedbed without the need for screens. The air from the air supply is provided with sufficient pressure that the seedbed is fluidized which decreases the need for mechanical agitation of the seeds.
