Comparison of Energy Consumption of Various Dryers in Plastic Pellets Drying
The project goal was to study effect of rotary dryers on the energy consumption and specific energy consumption of
polycarbonate (PC) pellets drying, the hopper dryer was compared. The PC pellets were dried with hopper dryer at 120 °C for 4 hrs in order to find the required moisture content then the PC pellets were dried at 80, 100 and 120 °C by both dryers until the required moisture content was achieved. The experiment showed that the required moisture content was 0.120% w.b., and rotary dryer could achieve faster the required moisture content of PC pellets than the hopper dryer leading to lower energy consumption and specific energy consumption of drying. Furthermore, color and shape of PC pellets were dried with both dryers of each
condition were not transform to degrade.
