Abstract: An apparatus for producing dry ice blocks includes an upper, charging mold having an outlet opening in its lower end and positioned in spaced relationship above a lower, press mold having an inlet opening in its upper end. The charging mold contains a slidable precompression piston and the press mold has a slidable press piston, the two pistons respectively being connected to actuators. A shutter assembly is positioned between the two openings, and includes a shutter having a forward extension which defines a recess therebeneath. The shutter is moved forwardly and backwardly by actuator means from a position wherein both openings are closed, to a position wherein, both openings are open, to a position wherein only the outlet opening is closed. Thereafter, the press piston forms the charge into a block of dry ice. The shutter is then shifted to the outlet only closed position, and the press piston elevates the block into the recess.
