DEVICE FOR PULSED HEAT TREATMENT OF BULK MATERIALS Russian patent published in 2009 - IPC F26B17/10 F26B20/00 

FIELD: motors and pumps.

SUBSTANCE: device for pulsed heat treatment of bulk materials consists of a cylindrical operating chamber of thermal activation with cover and beveled bottom. The operating wall of the housing is heated to 700-800°C to contact and activate thermally the particles of bulk material under action of centrifugal forces. The device also includes bulk material supply unit, steam and gas mixture discharge unit, hardening refrigerator adjoining the beveled bottom of operating chamber from outside, finished product unit to collect it under the refrigerator. The device also includes fluid-bed furnace where thermal activation chamber, hardening refrigerator with product accumulation chamber and gate valve are installed. The bulk material is supplied as gas suspension. The bulk material supply unit is represented as a nozzle with adjustable cap, which is cut into the internal wall of fluid-bed furnace.

EFFECT: device allows for producing thermally activated products with preset structure and properties.
