在研磨植物材料的提取过程中，首先从被研磨打开的细胞中提取容易接近的溶质，然后是被细胞壁保护的溶质的较慢的提取。在假定超临界溶剂塞流通过固定床层的基础上，建立了两个萃取周期的数学模型。在此基础上，建立了一个具有解析解的新模型。将模型计算的提取曲线与实验数据进行比较，确定提取参数。
During the extraction from milled vegetable material, the easily accessible solute from the cells opened by milling is extracted first, and the slower extraction of the solute protected by the cell walls follows. Mathematical models based on the assumption of plug flow of supercritical solvent through a fixed bed of milled material were published for both extraction periods. A new model with analytical solution was developed on the basis of these models. Extraction parameters can be evaluated by comparison of extraction curves calculated by the model with experimental data.
