发酵工序是发酵法生产味精的关键工序。发酵法是一种优良的味精生产方法 ,但它又是一种较难调控的生物化学方法 ,且影响发酵过程的因素多又错综复杂 ,人工调控难度大。利用微机技术对发酵过程的有关工艺参数进行实时采样、计算、分析和控制 ,实现发酵过程控制自动化。这对实现生产高效低耗和整个味精生产的自动化起到示范和推动作用 Fermentation process is the key process of MSG production. Fermentation method is an excellent MSG production method, but it is a more difficult to control the biochemical methods, and the factors that affect the fermentation process are complex and complex, difficult to manually adjust. Use of computer technology on the fermentation process of the relevant process parameters in real-time sampling, calculation, analysis and control, to achieve fermentation process control automation. This serves as a model and a catalyst for automation of production with high efficiency and low consumption and the entire production of MSG
