摘 要

本设计论证了味精工厂工艺的各个流程，包括原料预处理、水解糖的制备、淀粉的液化和糖化，种子的扩大培养，谷氨酸的发酵和控制，谷氨酸的等电提取，味精的中和脱色，味精的浓缩结晶和分离干燥等工艺。对整个工厂进行了物料衡算，水电汽用量的估算，对主车间采用的仪器设备的进行了论证和选型。同时对整个工厂进行了选址，车间平面进行了布局，并建立了HACCP体系。根据全厂进行了技术经济分析得出该项目的投资回收期为5年。利用CAD软件绘制了四张味精工厂的相关图纸。

年产8000吨味精厂发酵车间初步设计

ABSTRACT

This design demonstrates monosodium glutamate factory each process，consist of pretreatment of raw material，hydrolysis preparation of sugar，starch liquefaction and glycosylated，The expansion of bacteria cultivation，glutamate fermentation and control，The isoelectric point of glutamic acid extraction，decoloration and PH adjustment，MSG crystallization and separation and concentration。At the same time ,I maked the material calculation for the fermentation workshop, estimate the amount of water, electricity, gas;and selection of the main workshop equipment, established HACCP system.According to the plant's technical and economic analysis indicates that the project's payback period is only 5 years，with apparent effects.

Keywords: MSG, Technology demonstration、 Fermentation workshop、 Equipment selection、 Steam electricity estimate
