Device for high pressure processing of products

摘要

The device (1) comprises a high-pressure chamber (3), an outlet valve for discharging a high-pressure medium (12) from the high-pressure chamber, and a regulatable or controllable actuator (20), by which the rate of the pressure reduction in the high-pressure chamber is regulatable over a predetermined pressure range. The actuator is continuously adjustable, so that the rate of the pressure reduction is continuously adjustable. The actuator has a pressure intensifier, and is controllable by the pressure ruling in a pressure line, by an engine or by a compressed air. The device (1) comprises a high-pressure chamber (3), an outlet valve for discharging a high-pressure medium (12) from the high-pressure chamber, and a regulatable or controllable actuator (20), by which the rate of the pressure reduction in the high-pressure chamber is regulatable over a predetermined pressure range. The actuator is continuously adjustable, so that the rate of the pressure reduction is continuously adjustable. The actuator has a pressure intensifier, and is controllable by the pressure ruling in a pressure line, by an engine or by a compressed air or is hydraulically controllable. The outlet valve is a non-return valve, which adjusts itself in relation to the acceleration force. The device has a shut-off valve and a three-way valve that are provided between the high-pressure chamber and the outlet valve, where a first exit of the three-way valve guides to the outlet valve and a second exit of the three-way valve guides to the actuator. The actuator engages at the outlet valve. The high-pressure chamber is pressure-tightly lockable by a locking plug. The device includes a ventilation hole, by which the high-pressure chamber is ventilated when the high-pressure chamber is already locked using the locking plug. The ventilation hole is pressure-tightly lockable, and is arranged in the upper area of the high-pressure container. An independent claim is included for a method for high-pressure treatment of products such as packed foods.
