Supercritical fluid extraction technology different from the traditional steam distillation and organic solvent extraction method is a new, highly efficient, energy-efficient, and clean the oil extraction technology. Both in the maintenance of high extraction rate of the principle of energy conservation, this paper designed an annual capacity of 2000kg CO2 supercritical fluid extraction of aniseed essential oil proction. The design focuses on the proction line extraction conditions and specific description of the proction process. Described the design of supercritical fluid extraction principles; combination of star anise essential oil of the nature of the proposed extraction conditions for extracting pressure 15MPa, extraction temperature 40 ℃, CO2 flow rate 830 ~ 850L / h, extraction time of 2h, the extraction conditions selected temperature swing separation, further development of the star anise crushed, CO2 super-critical phase transition, extraction, separation and packaging processes; in determining the proction process on the basis of material balance, heat balance, extractor size calculation, piping calculation and packaging process is calculated; for the pollution occurred ring the proction, analysis of pollution sources, pollution control and waste treatment proposed measures; accounting of proction costs and value. The design of this proction line can provide guidance on the construction, but also the specific design of various equipment, basic materials.

Keywords: star anise essential oil, supercritical fluid extraction, proction, design

注意一下角标。比如CO2。
