hot air rotary dryer for seeds processing

Most of the drying takes place while the material falls through the air blast. Using very hot air or combustion gases, rotary dryers can also function as roasters for nuts, sesame seeds, and cocoa beans. A detailed method for the design of rotary dryers, based on a heat exchange approach has been described by Nonhebel (1971)

    Performance Analysis of Rotary Cotton Seed Dryer

    exposed to hot air from all sides, bed type dryer requires more amount of hot air. Also seeds which forms wall of the bed will be in direct contact of hot air, so these seeds will dry faster as compared to seeds which are in middle portion of bed. As a result non uniform drying of seeds takes place. This problem of non uniform drying can be solved by using rotary dryer. Rotary dryer consist of rotating

    Rotary dryers are used in the treatment of animal manure, wood slag, citrus peels, vegetable trimmings, alfalfa feed, rice with high moisture content, orange pulp used to complete the feeding with cereals of livestock animals. Some dryers can use very hot air that can be used to roast seeds. References. Whitten, Davis, Peck & Stanley. (2008). Chemistry. (8th ed.)
