超临界CO2萃取葡萄籽油的放大工艺研究
Research on the Up-sizing Technology of Grape Seed Oil Extracted by Supercritical-CO2
【摘要】 传统葡萄籽油提取存在不足,采用超临界流体萃取技术适宜用作提取。本文对超临界CO2萃取葡萄籽油的放大工艺进行了研究,其中试优化工艺参数为萃取压力25MPa,萃取温度为45℃,CO2流量为40kgCO2/h,葡萄籽油的萃取收率为8.92%,较小试有所下降。应加强节能(省气)、高效方面的研究。
【Abstract】 The traditional method of extraction of grape seed oil exists shortcomings.The technology of supercritical fluid extraction is suitable for the extraction.The up-sizing technology of supercritical CO2 extraction of grape seed oil was studied in this paper.The optimizing technical parameters are: extracting pressure at 25 MPa,extracting temperature at 45℃,CO2 flow rate at 40 kg/h.the extraction yield is 8.92%,which is less than the result of lab.Saving CO2 and increasing efficiency should be stressed in the near future.
