摘 要黄原胶是由甘蓝黑腐黄单胞菌利用碳水化合物产生的一种胞外杂多糖,它具有良好的水溶性、增粘性、假塑性和耐酸碱、耐盐及耐酶解的能力,被广泛应用于食品、石油、印染、纺织等领域。此次毕业设计的题目是年产 1000 吨黄原胶发酵工厂设计。为满足生产任务的要求,通过查阅相关的文献书籍,收集黄原胶发酵生产资料,从而设计出经济合理的黄原胶发酵生产路线。随后对工艺流程中所涉及的物料和热量等进行了衡算,同时完成了对主要生产设备和辅助设备的合理选型。另外,绘制出厂区总平面布置图、发酵车间的平面布置图、发酵车间立体布置图、全厂的工艺流程图、发酵罐的结构图和精馏塔的结构图。关键词:年产 1000 吨黄原胶;发酵;工厂设计AbstractXanthan gum is an anionic extracellular heteropolysaccharide produced by the bacterium Xanthomonas campestris XUB-11. It has good water solubility and viscosity, plasticity and increasing resistance to acid and alkali, salt and enzyme-resistant gum is widely used in petroleum, printing and dyeing, food, textile and other topic of this graduation project is an annual output of 1000 tons of xanthan gum fermentation plant design. To meet the requirements of production task, by reviewing some relevant articles and books, collecting the fermentation production of xanthan gum, thus scheme out the economic rationality of xanthan gum fermentation route. Subsequently to compute material and heat balance involved in the technological process ,and complete a reasonable selection of main production equipment and auxiliary equipment. In addition, draw the layout of the factory, chief fermentation workshop, floor plan, three-dimensional layout of the fermentation plant, whole plant process flow diagram, structure diagram of the fermentation tanks and distillation column chart.Keywords:an annual output of 1000 tons of xanthan gum; fermentation; plant design目 录摘 要...........................................................
