ABSTRACT:
A method and device for forming slabs of dry ice is shown. A dry ice extruding machine has been modified with a die that has a slot for extruding a slab of dry ice therethrough. The slot is blocked until a puck is formed in an end of a forming chamber of the dry ice extruding machine. The block is then removed and dry ice extruded to a desired length and then broken to give a slab of dry ice. The last step is repeated over and over as the extruded portion reaches the desired length to give the number of slabs wanted.
