The drum dryer uses hot air as the drying medium and adopts a cyclic drying process. The material is heated evenly and sufficiently, and the quality after drying is good. High-efficiency radiator, equipped with a reasonable air duct, is the hot air directly contacts the material, which greatly improves the drying efficiency and saves energy at the same time. The mixing blade is installed in the drum and the inertial mixing mode is adopted. The mixing effect is more uniform than the active mixing mode. , High efficiency and uniform heating.
