ABSTRACT:
The present invention is an apparatus for extruding various shapes and sizes of solid carbon dioxide units. The apparatus includes a computer-controlled extruder including removable dies for fabricating a wide range of dry ice shapes. A dagger board is provided for sectioning the extruded dry ice into desired lengths. Additionally, a linear voltage distance transducer coupled to the extrusion ram, in cooperation with pressure sensors in the extruding chamber, provide information to allow dry ice units having consistent density throughout to be fabricated.
