ABSTRACT:
The high pressure sterilization device comprises a sealed vessel (1) including a bottom wall (10) provided with an opening (12) connected to a source of pressurized fluid and a cover (20) attached to the bottom wall (10), and a slidable piston (30) mounted in a sealed manner in the vessel (1) and adapted to move in the vessel (1) under the effect of the pressure exerted by the fluid on an active surface (31) of the slidable piston (30). A high pressure treatment chamber (5) provided in the slidable piston (30) is adapted to receive the product to be sterilized, and a fixed piston (40) connected to the cover (20) is adapted to penetrate the high pressure treatment chamber (5) when moving the slidable piston (30) so as to compress the product to be sterilized.
