A polar green solvent based Microwave assisted oil extraction from low oil content source like bhat seed is one of the novel and sustainable approach. The understanding of exact mechanism of mass transfer and hence oil extraction is vital for its industrial scale application. The kinetics of oil extraction and their modeling is carried out in present investigation. The MAE of oil from different size particles (<1, 2, and 4 mm) of bhat seed sample was carried out through isopropanol as solvent. Fick's law based model and two stage (washing and diffusion) extraction based empirical model was fitted to the experimental data. Fick's law shown the best fit to all three particle sizes with R² .98, .98, and .97, respectively. The diffusion rate was observed to be decreased from 0.54 to 0.26 min⁻¹ with increase in particle size. Empirical model shown that the washing stage was most predominant over diffusion with extraction rate few hundred times the diffusion.

Bhat微波辅助浸提油的建模和动力学

一种基于极性绿色溶剂的微波辅助提取方法，该方法可从低油分来源（如hat子）中提取石油，这是一种新颖且可持续的方法。对于传质以及因此进行油萃取的确切机理的理解对于其工业规模的应用至关重要。在目前的研究中进行了石油提取的动力学及其建模。通过异丙醇作为溶剂对来自黑头种子样品的不同大小颗粒（<1、2和4 mm）的油进行MAE 。将基于菲克定律的模型和基于两阶段（洗涤和扩散）提取的经验模型拟合到实验数据。菲克定律显示最适合R ^2的所有三种粒径分别为.98，.98和.97。观察到随着颗粒尺寸的增加，扩散速率从0.54降低至0.26min ^-1。经验模型表明，洗涤阶段在扩散过程中占主导地位，萃取率是扩散过程的几百倍。
