Drying kinetiks rotary dryer

Drying kinetics is analyzed from three fundamental parameters in rotary dryers: drying air temperature, drying air velocity and alpeorujo sample size inside of the blades of the trommel. The outlet temperature of the Alpeorujo rotary dryers ranges between 80 C and 120 C, while the inlet temperature may fluctuate between 400 C and 500 C

    Theoretical Model for Predicting Moisture Ratio during

    A mathematical model was developed for predicting the drying kinetics of spherical particles in a rotary dryer. Drying experiments were carried out by drying fermented ground cassava particles in a bench scale rotary dryer at inlet air temperatures of 115–230 C, air velocities of 0.83 m/s–1.55 m/s, feed mass of 50–500 g, drum drive speed of 8 rpm, and feed drive speed
