Drying kinetics of black pepper dried in a spouted bed dryer with or without draft tubes

Abstract

Drying of black pepper has been studied in a lab scale spouted bed dryer. Experiments were carried out in a spouted bed dryer cither 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 wjthout degrading the quality of the material. periods, without existence of the constant rate period.
