Rotary Tube Furnace Dryers. An indirect dryer that allows a high degree of temperature control, a rotary tube furnace (RTF) dryer consists of electric heating device with a steel drum passing through it. Tumbling or rolling flights rather than the lifting flights such as those in the cascade rotary dryer are fitted to the inside of the drum. In operation, the particles are exposed to the drum surface, which is heated from the outside Shell with electric elements transfer. The internal flights tumble and mix the product, constantly exposing new surfaces to the heated drum surface. In addition there is a high degree of conduction between the product particles to enhance operation efficiency. This same principle is the basis for indirect calciners and reactors, which will be a topic for a future column.
