ConclusionsThe drying characteristics of kaffir lime leaves in a fluidized beddryer with the presence of inert particles were investigated at var-ious superficial air velocities and solid sample to inert mass ratios.Drying time decreased with the increased in superficial air veloc-ity. The Page model used to describe the drying kinetics of kaffirlime leaves gave satisfactory fit for all the data points with highercoefficient of determinations and lower standard error of estimates.It was found that the effective moisture diffusivities were around2.61 × 10−11–9.24 × 10−11m2/s for the range of experimental con-ditions studied. Fluidized bed dried kaffir lime leaves were brighterin color when compared to the sun and oven dried samples. Flu-idized bed drying presented the least color degradation comparedto the sun and oven drying. There was no significant loss in thecomposition of essential oil, vitamin C and A contents and the colorof kaffir lime leaves when drying in the fluidized bed dryer.
