ABSTRACT:
Pressurized colored liquids are inserted in the base mass, immediately upstream or in correspondence with the last homogenizing means; then a rotor arranged between the last perforated refining means and the extrusion hole, provides for a partial mixing of the paste. The speed of rotation of the rotor is adjustable from outside of the extrusion head, and independent of the speed of the extrusion screw.
