Introduction to rotary dryers
Rotary dryer operation. Rotary dryers consist of a large rotating cylinder (called the "drum") set horizontally but at a slight angle. Material passes through the drum and is heated by a heating medium according to a predetermined temperature profile and retention (or residence) time to achieve a target moisture content.

6. A rotary dryer consists of a cylindrical shell, set with its axis at a right angle to the horizontal and mounted on rollers so that it can be rotated. The material to be dried is fed to the high end of the dryer and, by rotation of the dryer, usually assisted by internal shelves of flight, is gradually advanced to the lower end where it is discharged.
