  • Patent number: 11123911
    Abstract: A cooling tool (1) for a food or an animal feed extruder (E), the cooling tool has: an inlet end (3) at which extrudate (4) can be led into the cooling tool (1); an outlet end (5) where the cooled extrudate can be discharged; an extrudate flow channel (6) extending from the inlet end to the outlet end; and at least one coolant flow channel (7a, 7b, 7b?) connected to the extrudate flow channel in a heat-transmitting manner. In a cross section (X-X) along the primary flow direction (8), the extrudate flow channel is substantially formed as a ring section; and the outer wall (9) of the extrudate flow channel (6) is formed at least from first and second segments (10, 11). The first and second segments are connected to each other by mechanical connection elements (12). The cooling tool is suitable for wet texturing of food and animal feed.

  • Publication number: 20120200000
    Abstract: The invention relates to a device comprising a substantially cylindrical housing (2) in a mixing region (7). Said housing comprises at least one outlet channel (15) having an outlet opening (6) in the mixing region (7) and at least one rotationally supported mixing shaft (4) having at least one discharge element (3) having an effective surface. The discharge element (3) can be guided past the outlet opening (6) when used properly, wherein a projection of the effective surface (8) parallel to the outlet channel axis covers the smallest outlet channel cross section of the outlet opening (6) at least once per revolution of the discharge element (3) by at least 45%, preferably by at least 50%, particularly preferably by at least 55%, and most particularly preferably by at least 60%.
