Background

Drying methods are many, such as sun drying, boil drying, oven drying, spray drying and vacuum drying, but these methods are carried out at temperatures above 0 ℃ or higher, and the dried product is generally reduced in volume or hardened in texture; some substances also oxidize and some volatile components are lost. Some heat-sensitive substances, such as vitamins, proteins, etc., can be denatured when dried at a certain temperature; the microorganisms lose their biological activity or the dried material is not easily dissolved in water. Freeze vacuum drying is a common drying method for preventing the denaturation of heat-sensitive substances in the drying process, and is called freeze drying for short. Freeze drying is one of the methods for keeping substances from being deteriorated. In the process of drying, a freeze dryer is often required to dry multiple samples at the same time, sample confusion can be caused due to poor classification, local temperature overheating or supercooling can be caused due to the fact that air does not circulate inside the freeze dryer when the freeze dryer is used for drying, the samples are not convenient to dry uniformly, bacteria can be easily accumulated at corners and the like inside the freeze dryer during the drying process, and the performance of the samples to be dried is not kept favorable and needs to be improved.
