When the materials are dried by air blowing or low pressure, the materials at the bottom cannot be completely dried if the drying time is too short, and the experimental time is prolonged if the drying time is too long. However, the powder-water mixture, the paste-like material, the gel-like material, etc. have problems that separation and drying are difficult. If drying is directly performed or drying is performed after filtering, the problem of agglomeration is inevitable, and the development of subsequent experiments is influenced to a certain extent.
