Device and method for the continuous high-pressure treatment of bulk material and use thereof

A method for high pressure treatment of bulk material by extraction, wherein the bulk material is positioned in a high pressure treatment volume of a pressure vessel apparatus and is treated at a high pressure level in a range from 40 to 1000 bar under isolation from the environment, wherein the method comprises:

• pressurizing the high pressure treatment volume;
• and high pressure treating the bulk material in a continuous manner at the high pressure level in the high pressure treatment volume, with continuity of the high pressure treating being assured 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 while the high pressure treating occurs, wherein during the high pressure treating discontinuous gravitational force-driven displacement of the bulk material occurs through the high pressure treatment volume by multiple discontinuous rotational or translational actuating movements, wherein the bulk material is disposed in a predefined first high pressure treatment plane and is then displaced continuously or between additional high pressure treatment planes within the high pressure treatment volume during the high pressure treating by virtue of the rotational or translational actuating movements, wherein the high pressure treating comprises at least one of:
• continuous displacement of the bulk material in two different predefined material flow directions within the high pressure treatment volume, including in a first material flow direction defined by the rotational actuating movements and a second material flow direction defined by the translational actuating movements;
• or
• continuous displacement of the bulk material counter to gravity by supplying potential energy to the bulk material by way of a rotational actuating movement;
• and
• depressurizing of the high pressure treatment volume.

A high pressure treatment system configured for high pressure treatment of bulk material by extraction at a high pressure level in a range from 40 to 1000 bar, the high pressure treatment system comprising:

• a pressurization device with pressurization generation means;
• a pressure vessel apparatus coupled to the pressurization device by a high pressure-tight connection, the pressure vessel apparatus including a high pressure-resistant wall that surrounds a high pressure treatment volume for the high pressure treatment, wherein the pressure vessel apparatus includes an actuator being rotationally or translationally displaceable and configured for a rotational actuating movement or a translational actuating movement, each for gravitational force-driven displacement of the bulk material through the high pressure treatment volume during the high pressure treatment;
• and
• a depressurization device coupled to the pressure vessel apparatus by a high pressure-tight connection,
• wherein the high pressure vessel apparatus is in a fixed arrangement and is configured to a continuous high pressure treatment solely by way of the high pressure treatment volume being in a fixed arrangement and at the high pressure level,
• wherein the actuator is configured to individually actuate a high pressure treatment plane of the pressure vessel apparatus or to simultaneously synchronously actuate multiple high pressure treatment planes of the pressure vessel apparatus, and wherein in the high pressure treatment volume multiple high pressure treatment planes are each defined by at least one gas-permeable plate with outflow chambers and with a passage segment.
