A continuous boiling apparatus (1) for organic materials, e.g. fish or offal from abattoirs, comprises at least one annular boiling zone (15) with an inlet opening (13) for the raw material and a discharge opening (4) for the heat-treated raw material. The annular boiling zone (15) is defined by circular, concentric heating plates (5), each made up of circular, concentric parts (6, 7) between which a heating medium is introduced (8). In the boiling zone (15) there are provided a number of feeding elements (10) with self-regulating scrapers (16) which lie up against heating surfaces (6) and divide the boiling zone (15) into sub-zones. |
