Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

在此基础上，从减轻废糟液处理负荷，实现清洁生产的需要出发，进行了无种子罐条件下酒精蒸馏废液直接全循环使用的自絮凝颗粒酵母酒精连续发酵实验研究，十三次全循环运行得到的实验数据，与无废液循环的实验结果相比，虽然平均发酵时间略增至30h～40h，但发酵终点酒精浓度仍达到12.5％以上，残还原糖和残总糖分别在0.70％和0.90％以下，说明循环积累物对发酵的影响有限，废糟液直接全循环使用的工艺技术路线可行。
