The model equation based on Fick’s second law was solved numerically in spherical coordinates and the average moisture content for each incremental interval (in dimensionless terms) plotted against dimensionless time values. The moisture content versus time curve had a good fit (R2 = 0.9997) with a model of the general form, MR = A exp (-ktn). The model was validated by using it to fit kinetic data from the drying of cassava particulate in a fluidized bed at 50°C. ER -
