ABSTRACT A carbon dioxide snow generator is disclosed which has a purge conduit for controllably delivering a blast of pressurized fluid at the inner surfaces of the generator to dislodge and remove any residual or clogging deposits of carbon dioxide snow. A vapor loop for such a generator is also disclosed which provides an initial blast of relatively warm carbon dioxide gas at startup which gas entrains and removes any residual liquid before it can freeze in the apparatus.
