Copper sulfide pentahydrate dried by microwave vacuum at low temperature
In the chemical industry, it often refers to the process of vaporizing water (or solvent) in materials by heat energy and taking the generated steam away by inert gas. For example, when drying a solid, water (or solvent) diffuses from the inside of the solid to the surface and then vaporizes from the solid surface. Drying can be divided into natural drying and artificial drying. There are vacuum drying, freeze drying, airflow drying, microwave drying, infrared drying and high frequency drying methods.
