Abstract
A carbon dioxide snow apparatus of the present invention includes a carbon dioxide snow generation system and a propellant generation system connected to a common carbon dioxide gas source. The carbon dioxide snow generation system includes a condenser having a at least two connected segments, wherein a first segment has a lesser diameter than the a second segment to provide a stepped expansion cavity for cooling and condensing liquid carbon dioxide into solid carbon dioxide snow. Several snow generation systems, each separately controllable with separate condensers, may be integrated with the propellant generation system and common carbon dioxide source to provide for a multiplicity of carbon dioxide snow applicators for integration into both manual and automated machining processes.
