ABSTRACT:
A method of controlling a CO.sub.2 snow-making operation which is promptly self-correcting should an upset occur that results in incomplete separation of CO.sub.2 snow from the cold CO.sub.2 vapor. The separated snow is fed to a generally closed chamber, while a major portion of the cold CO.sub.2 vapor is passed in heat-exchange relationship with warmer liquid CO.sub.2 flowing toward the expansion nozzle. The temperature and/or pressure of the CO.sub.2 vapor exiting the heat-exchanger is monitored, and upon detecting a condition indicative of incomplete separation of snow from vapor, the flow of vapor through the heat-exchanger is temporarily reduced while flow of a minor portion of CO.sub.2 vapor is permitted to exit from the generally closed chamber. Prompt correction of the situation causing the incomplete separation automatically results.
