甘草流浸膏原生产工艺为:提取→酒沉→取液→收酒→调整。为了提高收率,采取以下措施:①酒沉时在药液中缓缓加入85％乙醇,直至乙醇含量达65％左右。②酒沉搅拌时,先开真空泵使真空度达600mmHg、再打开酒沉缸底阀,使之充分搅拌、时间20～30min。采取以上措施后甘草甜素收率由70.2％提高至 The original production process of liquorice extract was: extraction→drinking→liquid extraction→collection→adjustment. In order to improve the yield, take the following measures: 1 Slowly add 85% ethanol to the liquor when the wine is drunk until the ethanol content reaches about 65%. 2 When the wine is stirred, first vacuum pump to make the vacuum up to 600mmHg, then open the wine sink bottom valve, so that it is fully stirred, time 20 ~ 30min. After taking the above measures, the yield of glycyrrhizin increased from 70.2% to
