The design of flights in rotary dryers
ResultThe solids should rain down over nearly 180° of rotation. In many cases, this is achieved by using curved flights of an appropriate shape that lift and then release gradually a large amount of solids. Good flight design is essential to promote the gas–solid contact that is required for rapid and homogeneous drying.

Dryer Design: Choosing the Right Drying Technology for …
ResultRotary Dryers are Direct Dryers designed with rotating, "tumbling" drums and internal lifters to "rain" the moist solid through the passing heated drying air. The challenge of this dryer is maximizing the time the wet feed is exposed to the heated drying air. The better the contact, the shorter the rotary dryer's length and cost.
