通过用糖蜜按不同比例取代木薯液化醪混合酒精发酵,并与纯木薯液化醪发酵进行对比试验,确定混合发酵的优势以及最佳混合比例,降低酒精发酵生产成本,以期实现燃料乙醇原料结构优化、降低成本的目的。经研究,添加糖蜜混合发酵可促进酒精发酵,在添加量为10%时产酒量最高,比不添加糖蜜酒分增加1.3%左右,但是提高酒精产量的同时,COD也随之升高,提高了污水处理的难度。
By using molasses instead of cassava liquefaction mixed alcohol fermentation in different proportions and comparative experiments with pure tapioca liquefaction mash to determine the advantages of mixed fermentation and the optimal mixing ratio and reduce the production cost of alcohol fermentation in order to achieve the optimization of the structure of the fuel ethanol feedstock, Reduce the cost of the purpose. Through the study, mixed molasses fermentation can promote the fermentation of alcohol, when the added amount is 10%, the amount of wine produced is the highest, about 1.3% higher than that without molasses, but at the same time, the yield of alcohol increases and the COD Sewage treatment difficulty.
