Fig. 5. a. Effect of air velocity on sawdust drying rate. Initial moisture content of sawdust
was 60 wt.% (wb) and bed and air temperatures were 90 °C. b. Effect of bed temperature
on sawdust drying rate. Initial moisture content of sawdustwas 60wt.% (wb). Air temperature
was 90 °C and air velocity was 0.32m s−1. c. Effect of particle diameter on sawdust
drying rate. Initial moisture content of sawdust was 60 wt.% (wb). Air temperature was
90 °C and air velocity was 0.32 m s−1.
