本设计按年产1500吨85%纯度乳酸的设计要求，以大米及麸皮为原料，选择德式乳酸杆菌为菌种，采用微生物发酵法生产乳酸，通过离子交换法提纯得到符合纯度要求的乳酸。根据年产量、物料衡算及水汽衡算的计算结果确定设备的选型。主要设备选取3台过滤面积为10m³的板框压滤机，2个预热罐，2个沉降罐，1个离子交换柱等。最后采用autocad软件绘制出工艺流程图，车间设备布置图及车间剖视图。

L - lactic acid  ;  Extraction workshop ;   design

This design according to the requirements of the design of the annual output of 1500 tons of 85% purity of lactic acid, with rice and bran as raw material, choose German type lactobacillus strains, using microorganism fermentation lactic acid production, to meet the requirements of the purity is obtained by ion exchange method purified lactic acid.The selection of equipment is determined according to the calculation results of annual production, material balance and water vapor balance.The main equipment selected 3 plate frame pressure filter, 2 preheating tank, 2 sedimentation tank and 1 ion exchange column.Finally, autocad software was used to draw the process flow chart, workshop equipment layout and workshop section view.
