INVESTIGATION OF DRYING BEHAVIOUR OF PUMPKIN IN A CYCLONE TYPE DRYER

Abstract

In this study, the drying behaviour of pumpkin was experimentally investigated in a cyclone type dryer. In the experiments, drying air velocities selected were 1 and 1.5 m/s, while three different air inlet temperatures of 60, 70 and 80 oC were used. The curves of drying rate-moisture content obtained from the experimental results were mathematically modelled using non-linear regression analysis.
