Apparatus and method for processing food or feed products with high meat content

摘要

The food or feed processing system 10, 96 includes an extruder 14 and a downstream machine 16, 16a, and is operable to process meat or feed ingredients. The machine 16 or 16a comprises a elongate work machine barrel 38 providing an inner surface 44 and a central body or tube 60 providing an outer surface 62 within the barrel 38 exist. Whereby the surfaces 38, 62 form a three-ring annular machining zone 70. The barrel 38 and the tube 60 are heated by the device 52, 66 with steam. The rotatable machining element 72 is also located within the zone 70. The element 72 has a plurality of helical vanes 88, 104 scraping the surface 44, 62 to prevent material accumulation on these surfaces.
