Pressure processing device

A pressure processing device for processing an object to be processed by coming into contact with a supercritical fluid, a sub-critical fluid or a liquefied gas, comprising,

• a pressure vessel comprising a cylinder, one end of which is closed, and a lid for closing an opening at the other end of the cylinder,
• a pressing means provided to press the lid in an axial direction of said cylinder with respect to said cylinder,
• a seal member provided between the open end of the cylinder and the opposed end of the lid opposite to the opened end of the cylinder,
• a diaphragm provided in the pressure vessel so as to form an airtight space that is separate from a processing chamber of the pressure vessel, and
• a unit adapted to mount an object to be processed, the unit being provided within said pressure vessel and outside said airtight space.

A pressure processing device in which an object may be washed, comprising:

• a washing vessel,
• a cylindrical housing vessel for housing a plurality of objects to be washed, provided within said washing vessel,
• a plurality of inlets provided on said cylindrical housing vessel for introducing the washing fluid into the cylindrical housing vessel, and
• a plurality of outlets provided on said cylindrical housing vessel for discharging the washing fluid outside the cylindrical housing vessel,
• wherein the openings of the respective plurality of inlets and plurality of outlets are formed and positioned so that the quantity of the washing fluid flowing on each object to be washed is substantially even.

A pressure processing device in which an object may be washed, comprising:

• a washing vessel,
• a housing vessel for housing a plurality of objects to be washed, provided within said washing vessel,
• an inlet provided on said housing vessel for introducing the washing fluid into the housing vessel, and
• an outlet provided on said housing vessel for discharging the washing fluid outside the housing vessel,
• wherein the openings of the respective inlet an d outlet are formed and positioned so that the quantity of the washing fluid flowing on each object to be washed is substantially even, wherein a plurality of corresponding inlets and outlets are provided on said housing, and wherein the inlet and the outlet sectional areas of said corresponding inlets and outlets become progressively larger at locations farther away from a position at which the washing fluid flows into the washing vessel.
