ABSTRACT:
A grain drier system is disclosed which includes means for collecting heated air which has passed through grain and conducting it to the inlet of the burners which supply the heated gas to dry the grain. The collected air is introduced into the inlet of the burner at the periphery of the air stream to the burner in an area where the contact between the collected air and the flame of the burner is minimized. This procedure enables the heat of the collected air to be utilized without the likelihood of subjecting any entrained material to the action of the flame of the burner.
In order to further minimize the possibility of fire, prior to being conducted to the burner, the collected air is passed into a plenum where the velocity of the stream of collected air is decreased and its direction of movement changed so that a substantial portion of entrained dust and organic material is caused to fall out of the air stream.
Cleanout doors and dump doors for rapid cleaning and unloading of, respectively, the drier are also disclosed.
