  • CO2 SUPPLY SYSTEM
    Publication number: 20090114290
    Abstract: The present invention relates to a CO2 supply system. A condensing container is used to transform gas state CO2 from a gas state CO2 supply source into liquid CO2. Therefore, a liquid CO2 with stable pressure and stable flow rate could be provided (for example, supplied to a nozzle module to produce a great quantity of solid state CO2 and gas state CO2). Whereby, the usage of CO2 can be reduced, so that the greenhouse effect can be alleviated and the manufacturing cost can be decreased.
