The invention relates to a drum cooker (10) for cooking granular products, especially maize grits for producing cornflakes. Said cooker comprises a container (12) which can be rotated about an axis (13) and nozzles (26, 27; 30, 31) which discharge into the container (12) and are connected to ducts (24, 29) through which a gaseous heat-carrying medium (35) can be introduced into the container (12). The invention provides for at least two nozzles (26, 27; 30, 31) to be distributed on the circumference of the container (12) so that at least one nozzle (26, 27) discharges into the area (33) covered by the product to be cooked and at least one nozzle (30, 31) discharges into the area (39) not covered by any product to be cooked. To allow for heat-efficient and rapid cooking the invention provides for a control device (32) by means of which only those nozzles (26, 27) are supplied with the medium (35) which at any given time discharge into the area (33) covered by the product to be cooked. |
