Valine separation and purification device

According to the valine separation and purification device provided by the utility model, the sedimentation tank, the primary filter, the secondary separator, the detection tank and the concentration crystallizer are arranged, so that the treatment of sedimentation, primary filtration, secondary separation and concentration crystallization of valine fermentation liquor is realized, and various impurities of the valine fermentation liquor are comprehensively treated; the purity of the treated valine crystals is greatly improved. The detection pool is arranged in front of the concentration crystallizer, so that sampling detection can be performed on valine fermentation liquor subjected to front-stage treatment before concentration crystallization, and the purity of finally obtained valine crystals can be effectively ensured. 本实用新型提供一种缬氨酸分离提纯装置，通过设置沉降池、一次过滤器、二次分离器、检测池和浓缩结晶器，实现对缬氨酸发酵液的沉降-一次过滤-二次分离-浓缩结晶处理，全面针对缬氨酸发酵液各种杂质进行处理，大大提高了处理后的缬氨酸晶体的纯度。在浓缩结晶器前设置检测池，可以在进行浓缩结晶前对前段处理的缬氨酸发酵液进行取样检测，可以有效保证最后得到缬氨酸晶体的纯度。
