A rotary dryer is used for fairly free flowing feeds, with a narrow to wide particle size distribution and for both small and large size particles. Wet and pasty materials can be dried when the feed is back-mixed with dry product. Air flow can be parallel or countercurrent to the solids flow.
Agricultural products are highly perishable and drying of the product after harvest has been proved as one of the methods to minimize postharvest losses.
Rotary dryers are capable of processing a variety of agricultural products with a wide range of thermo-physical and flow properties. Rotary dryers have been used for drying of grains, beans, nuts, vegetables, herbs, woody biomass, animal feeds, agricultural wastes, and by-products.
