摘要：A device for producing a block of solidified carbon dioxide essentially

comprising a high pressure vessel of liquidified carbon dioxide, a thermally insulated highpressure feed tube and a molding box in which a product of solidified carbon dioxide ismolded in the form of block, wherein the molding box contains a single molding chamberin a cubic structure which consists of a top cover, a pair of first side walls, a pair of secondside walls and a base board, each of which members is designed so as to be easilyassembled or disassembled, said first and/or second side walls being formed with aplurality of openings through which gaseous medium flows and being provided with alayer of filter fixedly secured to the inner wall thereof respectively. The base board andthe second side walls are formed with engagement grooves for allowing the first andsecond side walls and base board to be easily assembled or disassembled. Furtherlocking means are provided for ensuring tight locking of the molding box. In an

alternative embodiment the molding box may contain a plurality of molding chambers ofwhich number correspond to that of blocks of solidified carbon dioxide to be produced.Liquidified carbon dioxide is delivered to a common distributor via the high pressure feedtube and then distributed to each molding chamber through a lever operated pressure

reducing valve and nozzle means.
