Abstract
A cooling mixer for bulk material, especially plastic material, in powder and granular form has a cylindrical container with a bottom portion, the container having a container double wall with an intermediate space and at least one outlet opening at the bottom portion. A cover for closing the container is provided and has at least one feed opening. The cover has a cover double wall with an intermediate space. A rotating mixing device comprised of a hub and mixing paddles fixedly connected to the hub is concentrically connected to the container such that a vertical rotating axis of the mixing device coincides with the axis of the container. The coolant circuit containing a coolant that is circulated during operation of the cooling mixer within the intermediate spaces comprises connectors for connecting the coolant circuit to the container double wall and the cover double wall. The container has a diameter to height ratio of 4:1 to 8:1. The mixing paddles form an obtuse angle with the bottom portion in the direction of rotation of the mixing device for vertically deflecting the bulk material to be cooled.
