Dried long-grain rough rice (paddy) with moisture contents
in the range 12–14% (dry basis) was selected as the test material. 0.8 kg of paddy, which created a non-fluidized
bed height of 4 cm, was loaded into the fluidized
chamber for each experiment. To guarantee complete fluidization
of paddy is attained, the fluidization velocity of
2.5 m/s, which is equal to 1.5 times of the calculated minimum
fluidization velocity (1.65 m/s),
