<p><P>PROBLEM TO BE SOLVED: To provide a system for producing dry ice with reduced power by effectively utilizing the CO<SB>2</SB>gas exhausted during the conventional production of dry ice, and to provide a scrubbing system of dry ice blast by which dry ice can be effectively reused on application of such a system. <P>SOLUTION: The system 1 for producing dry ice is provided with a dehumidifier 2 that removes moisture from a gas containing CO<SB>2</SB>, a refrigerating machine 3 that uses air as a refrigerant by which the gas containing CO<SB>2</SB>having been removed moisture is cooled, and a separation apparatus 4 that separates dry ice produced from the cooled CO<SB>2</SB>, and also the method for producing dry ice using the system is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
