High thermal efficiency: The drum dryer operates on heat conduction principles, ensuring consistent heat transfer direction throughout the cycle. Except for minor heat loss through covers and radiation, nearly 70-80% of the heat is utilized for moisture evaporation.
Flexible operation & broad applicability: Key parameters—such as feed concentration, material film thickness, heating medium temperature, and drum rotation speed—can be adjusted independently to optimize drying efficiency for diverse materials and production requirements.
Short drying time: Drying cycles typically range from 10 to 300 seconds, making it ideal for heat-sensitive materials. When installed in a vacuum chamber, it can operate under reduced pressure.
High drying rate: The material film thickness (0.3–1.5 mm) and aligned heat/mass transfer directions enable an evaporation intensity of 20–70 kg·H₂O/m²·h at the film surface.
