年产4000t酒精厂设计..docx

本科生课程设计（论文）题目：年产40000吨酒精工厂设计——蒸煮糖化车间 学院 专业学 号 学生姓名 指导教师 二〇一六年五月摘要酒精在人们日常生活以及科学研究等诸多领域都有很广泛的应用。世界酒精行业以及我国酒精行业都呈现快速发展趋势，产量逐年递增。发酵法生产酒精的能力将成为一个国家经济实力的标志。发酵法主要是利用微生物无氧发酵，将含糖物质如，甘蔗，甘薯，玉米等物质内的糖类转化为乙醇，生成酒精。此法原料来源丰富，生产过程环保，值得大力推广。本设计对酒精生产的蒸煮糖化车间进行了计算和设备选型，力求理论和实践相结合。AbstractAlcohol has very extensive application in a great deal of fields such as peoples daily life and scientific research. The trades and alcohol trades of our country have fast development trends on earth in the world. The output is increased progressively year by year. The ability for producing alcohol of the fermented law will become the sign of a national economic strength. The fermented law is mainly to utilize microorganism to have no oxygen to ferment, it suck candy material like, sugarcane, sweet potato, carbohydrate in the material such as the maize are turned into ethanol, turn into alcohol. This law raw material sources are abundant, the environmental protection of the production process, is worth popularizing in a more cost-effective manner. Originally design the pulping workshop produced to alcohol to calculate with the selecting type of the apparatus, strive to make the theory combine with practice.关键词： 酒精 淀粉 蒸煮 糖化 衡算 工艺流程目录第1章 绪论·································································31.1 酒精的性质······························································31.2 酒精的用途······························································31.3 酒精工业的发展··························································31.4 生产方法及目的··························································31.5 食用酒精国家标准························································4第2章 工艺论证·····························································52.1 原料的选择······························································52.2 原料的预处理····························································52.3 原料的输送······························································52.4 原料的蒸煮工艺················································
