Abstract
The present invention relates to an isostatic press for high pressure treatment of a product having a temperature below 0° C., said isostatic press comprising a pressure chamber adapted to contain a first pressure medium, and a container which is placeable in the pressure chamber. The container which is placeable in the isostatic press is adapted to hold the product and a second pressure medium, the container being closable to keep the first pressure medium separated from fluid communication with the second pressure medium. The container is further provided with a pressure transfer device adapted to transfer pressure from the first pressure medium to the second pressure medium, and a body which is made of a material with low adiabatic heat emission relative to adjoining substances, so that the body from adjoining substances absorbs heat, which is generated by adiabatic temperature rise during the high pressure treatment. The invention also relates to a method, a container, and a plant for high pressure treatment of a product having a temperature below 0° C. by means of an isostatic press.
