摘　　要：渗透汽化技术是一种新型的膜分离技术和清洁生产技术,在发酵工业中具有广阔的应用前景。简单介绍了各种乙醇发酵工艺及其存在的问题。综述了渗透汽化在乙醇生产中的应用,包括乙醇连续发酵、无水乙醇制取、改善白酒风味、低醇和无醇饮料酒生产4个方面。指出了渗透汽化技术在应用过程中存在的问题和未来研究的方向。Being a new membrane separation technique and a new clean production technique, pervaporation has wide application foreground in fermentation industry. In this paper, various ethanol fermentation techniques and the existing problems were introduced briefly. The application of pervaporation in ethanol production in four aspects including ethanol production with continuous fermentation, anhydrous ethanol production, improvement of liquor flavor, low-alcohol and alcohol-free beverage wine production were summarized. The existing problems and the research direction of pervaporation technique were also put forward.
