Single pass rotary dryers use heated gas to dry moist material circulated through a rotating drum. Inwardly extending flights mix particles so that they move around, facilitating the evaporation process. These dryers tilt, putting gravity to work moving the materials as the drum spins.
Materials move unidirectionally through the single cylinder and are blasted by gas to reduce moisture content. In addition, single pass dryers optimize the airstream. They typically include spiral flights to speed up or slow down motion, giving you greater control over moisture removal or retention. To achieve this, we can add different patterns of spiral flights throughout the drum. These flights act like a screw conveyor. Depending on the configuration, this increases or decreases retention time.
