<p>An apparatus for forming an extruded ice cream bar with variegated inclusions. The apparatus includes a main die (12) having a section with sidewalls (44) extending between upper and lower end portions (32,34) and defining a cavity (30). In the preferred embodiment, a plurality of intermediate dies (24,26) for insertion of the inclusions are positioned within the cavity (30) and spaced from the sidewalls (44) of the main die (12). The intermediate dies (24,26) gradually and progressively change in cross-sectional shape from being round at the top to the desired shape of the inclusion at the bottom. As the ice cream flows through the cavity (30) of the main die (12), it passes along and about the intermediate dies (24,26) through which the inclusions are flowing. Each intermediate die (24,26) is preferably fed by two tubes so that the final shape of the inclusion at the bottom of the intermediate die is fully and evenly filed. The intermediate dies (24,26) are preferably made of heat conductive, metallic material wherein the surrounding ice cream in the main die (12) will gradually and progressively cool the hotter inclusions in the intermediate dies (24,26) before they reach the insertion locations. <IMAGE></p> |
