【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 CO₂ drying, low-temperature supercritical CO₂ extraction drying and rapidly high-temperature supercritical drying, etc. as well as their characteristics were also discussed.更多还原
