1. A method for high pressure treatment of bulk material by extraction, wherein the bulk material is disposed in a high pressure treatment volume, which has cavities, of a pressure vessel apparatus and is treated at a high pressure level in a range from 40 to 1000 bar, wherein the method comprises:
pressurizing the high pressure treatment volume;
high pressure treating the bulk material in a continuous manner in the high pressure treatment volume, with continuity of the high pressure treating being ensured solely by way of the high pressure treatment volume, wherein the high pressure treatment volume or the pressure vessel apparatus is in a fixed arrangement during the high pressure treating, wherein the high pressure treating comprises continuously displacing the bulk material by translation of a translational actuator within the high pressure treatment volume; and
depressurizing the high pressure treatment volume.
