MSG has a strong flavor, its unique flavor can increase the flavor of food, causing peoples appetite to help improve the bodys digestion of food. Sodium glutamate into the human body can quickly break down the glutamate, is the bodys normal metabolism of substances plays an important role in human metabolism. MSG originated from Japan, Chinas MSG production began in 1923, to the 1980s, entered a rapid development stage, after years of development, the MSG industry continues to expand the scale of production as the world. MSG production, including three section are fermented section, section extraction and purification section. The design is based on 42000 tons of starch fermentation section of monosodium glutamate factory design, the design uses dual enzymatic process for the production of sugar saccharification of raw materials, the use of temperature-sensitive mutants of glutamic acid fermentation. Which includes the design section of the fermentation process design, equipment selection and design, the mass balance of the entire production process of MSG count, water and heat balance accountancy. The purpose of this design is from the actual production to ensure that all aspects of production using less manpower, material and financial resources in order to achieve greater economic benefits. Key words：MSG； glutamate； saccharification； fermentation； accountancy  目 录 摘 要 I Abstract II 第1章 绪 论 1 1.1 味精工业简介 1 1.1.1 味精的性质 1 1.1.2 行业的发展现状 1 1.2 本设计内容 2 2 1.2.2 主要内容 2 1.2.3 研究方法 2 1.2.4 厂址选择 2 1.3 味精生产工艺流程及主要过程 3 3 第2章 物料衡算 5 2.1 生产过程的总物料衡算 5 2.1.1生产能力 5 5 2.1.3 物料衡算 6 2.1.4
