This study was performed to carry out the separation, drying and conveyance of grains by fluidization. The soy bean, red bean, unhulled rice, brown rice, barley and rape seed were fluidized by air and the air distributors were used the fabric (felt) and wire screens (150, 50, 30 and 10 mesh).
As the results, the minimum fluidization velocities of these grains were 0.6-1.7m/sec and the velocity of large graing was larger than small ones.
The fluidized states varied with the size of the grain, the kind of the distributor and the initial bed height and the phenomena of the channeling and slugging occured under particular conditions.
As grains were not fluidized uniformly in these experiments, further investigation is needed to understand these phenomena clearly before applying the fluidization to the separation, drying and conveyance of grains.
