Soponronnarit et al. (1995) described the design and testing of
a prototype fluidized bed paddy dryer with a capacity of 0.82 t/h. They used air temperature
of 100-120°C, fraction of recycled air of 0.66, specific airflow rate of 0.05 kg/s-kg dry matter,
superficial air velocity of 3.2 m/s, and bed depth of 0.1 m to reduce paddy moisture contents
from 45% to 24%. They also found that electrical and thermal energy consumptions in terms
of primary energy were 0.53 and 1.79 MJ/kg water evaporated, respectively.
