High-pressure vessel extraction kettle is used to contain the material to be extracted. It is usually made of pressure-resistant materials and can withstand the high pressure of supercritical carbon dioxide.
Supercritical CO2 fluid extraction kettle is one of the keys to the development of supercritical extraction technology. It needs to solve the problems of machinery, heat exchange, fluid transportation and safety assurance caused by the process under high pressure (generally 8-35Mpa or higher). It should be safe, easy to operate, highly versatile, and can be operated continuously on the premise of meeting the production purpose.
