Studies on drying kinetics using fluidized bed dryer

Abstract

A study has been conducted on the drying kinetics of vegetables in a fluidized bed drier. Some physical characteristics of different vegetables were determined as a function of moisture content. Parameters like time of drying, temperature of air, flow velocity of air and material to be dried were varied and the drying rates were determined. The effects of different parameters like temperature, time and velocity on drying kinetics were determined. Critical moisture content was also determined. The drying kinetics of vegetables was thus obtained from these data by considering the different experimental conditions. Effect of diffusivity also observed.
