  • Rotary Dryers - an overview

    Rotary dryers are mainly used in the chemical and mineral industry. In the area of food, their most common applications are for dehydrating waste materials (citrus peels, vegetable trimmings) and animal feedstuffs (alfalfa). Rotary dryers consist of a metal cylinder with internal flights or louvers (Fig. 22.21 ). The cylinder is slightly inclined.
