METHOD AND APPARATUS FOR HIGH PRESSURE TREATMENT OF SUBSTANCES UNDER CONTROLLED TEMPERATURE CONDITIONS

摘要

A product carrier (10) for use in ultrahigh pressure processing substances i s substantially fluidically closed, and is insulated, to prevent heat transfer from the product being treated to the cooler wall of the pressure vessel. Th e insulating material (18) has compression heating properties, such that as th e product is pressurized, the temperature of the insulation increases as does the temperature of the product and pressure media, thereby helping to preven t heat transfer from the product to the surrounding media and pressure vessel wall.
