Method for processing by heating and equipment for same

摘要

In a method for processing by heating a powder-like and/or granular substance including steps of charging the powder-like and/or granular substance as a matter to be processed into a heated and pressurized direct-heating medium stream, heating to process while transferring the powder-like and/or granular substance in a heating tube (4), and thereafter discharging the powder-like and/or granular substances from the heating tube (4), the direct-heating medium stream is forced to whirl for heating to process while spirally transferring the powder-like and/or granular substance in the heating tube (4). The powder-like and/or granular substance as heated to be processed is discharged out of the heating tube (4), through a discharge mechanism (5) adapted to control the pressure in the heating tube (4).
