摘　　要：从啤酒酵母泥中压滤得到的废啤酒含有约4.5%vol的酒精,将其蒸馏可得到用于白酒生产的优质酒精。研究了回流比、起始酒精浓度等对蒸馏效果的影响,正交实验确定了最佳的工艺参数为:酒精起始浓度为60%vol,回流比为3,酒头提取量为3%,酒尾提取量为14%。该工艺生产制得的酒精的各项主要指标均达到甚至优于国家食用酒精的标准。Waste beer separated from beer slurry contained about 4.5 %vol alcohol. After the distillation of the waste beer, quality alcohol suitable for liquor production could be obtained. The effects of reflux ratio and initial alcohol concentration on distillation effects were studied and the best technical parameters were determined through orthogonal experiments as follows： initial alcohol concentration as 60 %vol, reflux ratio as 3. 3 % extraction quantity of head beer and 14 % extraction quality of ending beer. Each main index of the produced alcohol met and even was better than the standards of national edible alcohol.
