谷氨酸浓缩连续等电与转晶工艺技术研究

Glutamate concentration for new technology research such as electricity and crystal In electrical method extracting glutamic acid process,optimizating initial concentration and continuous electric temperature is the main way to improve the extraction yield of glutamic acid. Crystal is one of the ways to improve the quality of secondary crystallization of glutamic acid. Experimental studied on solid-liquid ratio, temperature and pH value on the influence of glutamic acid crystal, abtain an ideal crystal conditions: glutamic acid initial material liquid concentration 30%, continuous electric temperature 45 ℃, solid liquid ratio78% , temperature 90 ℃, pH4.6.
