From the experimental results of fluidized bed drying, it could
be concluded that the percentage of cracking of soybean kernels
(31.80–58.22%) increased with drying temperature, air
velocity and drying time. Effect of air temperature on the quality
parameters of soybean kernels was more than that of air
velocity. The highest rehydration ratio (0.873) was obtained
at 80 C and 3.1 m/s, while increasing drying air temperature
also increased it. Besides, increasing the drying air temperature
decreased kernels’ bulk density (1186.39–1101.31 kg/m3) and
degree of shrinkage (0.787–0.730), while air velocity had no
significant effect on shrinkage or bulk density.
