Drum drying characteristics of pumpkin pulp were investigated by using a single drum dryer with applicator rolls. The drum drying process was divided into two phases: pulp phase and flake phase. Under these two conditions, moisture content of the samples under different steam pressures was measured in order to analyze the relationship of the drying rate with the inner pressure and drying time. It indicated from the results that, most of the moisture evaporated during the pulp phase. The higher the steam pressure was, the higher the drying rate became. It was also shown that during the flake phase, only falling rate period was taken place. As the steam pressure increased, on one hand, the initial moisture content of flake phase became less and the drying rate became decreased, on the other hand, the decreasing of the drying rate was slow down and the drying time was much shorter. The experimental moisture loss data were fitted with 10 thin-layer drying models. Consequently, of all the drying models, a semi-theoretical Midilli-Kucuk model was fitted best.
