Drying of black pepper has been studied in a lab scale spouted bed dryer. Experiments were carried out in a spouted bed dryer either with or without internal devices. The two different internal devices of the dryer are namely non porous draft tube and porous draft tube. Effect of drying temperature, type of drat tube, diameter of draft tube and stagnant bed height on drying kinetics were analyzed. The highest drying rate was achieved when black pepper was dried without draft tube at highest drying temperature. Drying kinetics of black pepper in spouted bed dryer indicated only induction and falling rate periods, without existence of the constant rate period.
