The authors investigated a fluidized bed drying of cereal grains and the following results were obtained.
1. The minimum fluidizatiop velocity of unhulled rice, hulled rice, wheat, millet and soybean was 1.08, 1.04, 1.05, 0.80 and 1.28 meters per second respectively which agreed with the values calculated by Leva's equation (eq. 4).
2. When the unhulled rice was dried by fluidized bed drying, the average drying speed was about 3 percent per hour and the rate of cracking-kernels increased with drying temperatures over 40°C. However, under the drying temperature of about 30°C, the average drying speed was 2.57 percent per hour and the rate of cracking-kernels was 5 percent.
3. The drying equation for the thin layer (eq. 5) could be applied for estimating fluidized bed drying quantitatively.
