Method and apparatus for the extrusion of material

摘要

Apparatus and a method for the formation of extruded materials such as ice cream products, wherein the exuded product has located within it further exuded material, said material being visually distinguishable wherein the extruded material is manipulated during passage through an extrusion die unit (22) to ensure the complete fill of the shape and an even extrusion by controlling the rate of flow and directional movement of the material as it moves through the die by means of projections (24) in the form of vanes and restrictors formed on the die extrusion unit (22).
