The heat source of grain dryer drum is from combustion devices. This grain dryer drum adopts direct flow heating method. So the material should be sent to the shell by the feed chamber and feed chute. After that the material will be pushed backward by the spiral shoveling plate.

As the grain rotary drum dryer is located with a tilt, the material flows to the end by the gravity. Meanwhile, it is shoveled repeatedly by the shoveling plate to the upper end then comes down constantly, forming an even curtain in the drum and exchanging heat fully with the hot current in the drum. With the material being raised and scattered again and again, the moisture is dried gradually. Finally it is dried totally.
