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