| Sorghum bicolor also called Lu su, Sweet sorghumstalk, Sweet shot and Sugar sorghum, which is a variety of sorghum using by its grain。Because of its high output, easy cultivated, extensive use, moreover the sugar of its stalk can easily transform to ethyl alcohol, which is a substitute for petrol. As a result, many countries attach importance to cultivate the sorghum bicolor as a energy crop.Taking the stems of sweet sorghum Jiutianliang#1 as test material, definite the best solid fermentation and liquidfeimentation condition of the sweet sorghum stems, and test the jucie to instead the water to feed preparation,definite the best condition of the holding period of jucie. So the main conclusions are:1.The best condition of solid feimentation are:the pit entry temperature is 18℃, the fermentation time is 72h, the yeast addition quantity is 1.5‰, the Brix of stem is 20°Bx.2.The best condition of liquid feimentation are:the fermentation time is 72h, the yeast addition quantity is 1‰, the Brix of stem is 22°Bx, originate pH is 4.6.3. We have studyed the smatch-production of sweet sorghum, maximum ethanol production term is 6 months, natural freezing storage is 5 months.4. The jucie can be reserved for a month when the pH is 4.0. The jucie can be reserved for 61 days by regulate the pH after a month.Choose a good sweet sorghum to improve its cultivation technique by lots of related experiments.Improve the equipment and technology of simple solid state fermentation to make ethanol by stems of sweet sorghum.Use the special natural conditions of the northeast in winter to study the storage technique of stems of sweet sorghum. Build a high yield and high glucose demonstration baseof sweet sorghum in vast rural area for two years. cooperation with ethanol factory,the crude ethanol to distillation by the ethanol factory.We resolve many technical difficulties, basically realized the effective connection of sweet sorghun, s plant,crude ethanol, s process and the ethanol factory. Greatly promote the industrialization of stems of sweet sorghum to make ethanol, accumulated the valuable experience for the biomass energy, s sustainable development. |
