Autoclave is a common pressure vessel and belongs to special equipment. It is widely used in the industrial field, mainly for the material treatment in the process of heating, evaporation, concentration and drying. Its main structure is generally composed of autoclave body, conical cover, heat transfer plate and support frame.

The working principle is to use steam heating to process the heated material. During the heating process, steam enters the tank through the steam valve. Heat is exchanged with the material on a heat transfer plate to heat the material to the desired temperature.
