| Abstract: | The supercritical extraction kettle should meet the requirements of pressurization and quick opening. Based on the analysis of three kinds of common - used quick - opening seal connections, a new quick - opening seal connection was developed. The pneumatic servomechanism was applied to realize the automatic open and close of the head cover of supercritical extraction kettle. A supercritical extraction kettle with the new quick -opening connection was designed, and its safety and reliability was also validated by strength analysis. |
