  Continuous flow dryer - IRRI Rice Knowledge Bank

  2020311 · In counter flow dryers the air moves upwards against the movement of the grain. This system is very energy efficient since the drying air continues to adsorb moisture on its way through the increasingly wet grain until the air outlet. Mixed flow dryers produce the best quality grains because of the continuous mixing effect.
