Vacuum freeze-drying, also known as sublimation drying. The principle is to freeze the material, make the water condensed into ice, and then sublimate the ice in vacuum environment to achieve the purpose of drying. The advantage of vacuum freeze-drying is that can maintain the morphology and structure of the sample as far as possible during the drying process.
