<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for efficiently recovering and reusing carbon dioxide exhausted from a dry ice jetting apparatus. <P>SOLUTION: Carbon dioxide G jetted by a dry ice jetting apparatus is efficiently recovered by a recovering blower. The recovered carbon dioxide is efficiently reused (1) as an atmospheric gas G<SB>A</SB>to keep the inside pressure of a washing box always positive, (2) as a carrier gas G<SB>c</SB>for heating and accelerating obtained by pressurizing the recovered gas with a compressor, and (3) as dry ice D, a washing medium, obtained by compressing the recovered gas and liquefying it with a refrigerator. <P>COPYRIGHT: (C)2004,JPO |
