Abstract

PURPOSE: To obtain the snow like dry ice with a high void ratio by mixing a gas having a liquefaction temp. lower than that of a low temp. liquified gas for solidifying carbon dioxide gas to carbon dioxide gas in a specific ratio to freeze the same.
CONSTITUTION: As the gas for liquefying CO2 gas, oxygen is used for example and, as a mixed gas, nitrogen is used for example and a volume ratio of CO2 and N2 is adjusted to 19:1W1:19. The CO2 gas and the N2 gas are supplied into a dry ice making cylindrical main body 7 in a predetermined ratio from a supply pipe 1 and a supply pipe 8 respectively and recirculated by an axial flow type blowing fan. The liquefied oxygen is supplied from an inlet 18 and flowed out from an outlet 20 to cool the mixed gas and, therby, only CO2 is frozen in a snow like form. CO2 is replenished from the supply pipe 1 by operating a pressure detector 16. If a layer with a predetermined thickness is formed, the supply of the liquified oxygen is stopped and a warmed O2 gas is sent into from a supply pipe 31 to drop the adhered snow like dry ice into a press packing and molding cylinder 37 and said dry ice is compressed and molded by a piston 40.
