ABSTRACT:
Apparatus for pressure processing components is disclosed which includes an improved closure system that minimizes dust-generating parts and allows easy access to the chamber. Ports are provided for introducing and releasing pressurized gases and fluids to and from the processing space. The heating system of the apparatus heats both the cover and the stage inside the pressurized chamber such that cycle time to equilibrate heated, pressurized fluids such as supercritical carbon dioxide inside the chamber are decreased. The apparatus includes a mechanism that raises the stage inside the chamber, pressing it against the fixed cover and sealing the inside of the pressure vessel. In one embodiment a screw-type jack is used to move the component-loaded stage fitted with a deformable o-ring seal a short travel distance to seat against the lid and seal the pressure chamber. In a related embodiment a computer and an electronic stepper motor are used to drive the pressing means in an automated fashion.
