超临界二氧化碳萃取藿香叶浸膏的数学模型

The Mathematical Model on Extraction of Patchouli Leaf Concrete by Supercritical Carbon Dioxide Fluid

考察在超临界二氧化碳萃取藿香叶浸膏工艺中萃取时间、二氧化碳流量、萃取温度、萃取压力四个因素对萃取率的影响。利用单因素试验以及正交试验得到相应实验数据,对这些数据进行多元多项式拟合,得到反映工艺条件与萃取率之间关系的数学模型,由此模型计算出最佳工艺条件。

Single factor experiment and orthogonal experiment are adopted to investigate extracting time, CO2 flow rate, extracting temperature and extracting pressure on the chouli leaf concrete by supercritical carbon dioxide fluid. The approximate mathematical obtained by multiple polynomial fitting the experimental data, and conclude the optimal conditions of extraction. the effects of yield of patmodel can be technological
