| Abstract: | The principles and routes of supercritical drying operation were reviewed. Steps and time needed for supercritical drying process were discussed. Several new procedures of supercritical drying, such as high-temperature supercritical drying, low-temperature supercritical CO_2 drying, low-temperature supercritical CO_2 extraction drying and rapidly high-temperature supercritical drying, etc. as well as their characteristics were also discussed. |
