Select Sweet potato，then we could get the product by the way of saccharification and fermentation ，The Fermentation Liquid, forms during fermentation, go through the preheater, then exchange the heat with the alcohol steam came from the rectification column. Then we could get 95% medical alcohol after going through the Crude distillation tower, refining in the rectification column. Then do the material balance and the heat, compute the condenser equipment selection. Use AutoCAD software to draw the technological flow chart with control points, equipment layout of distillation , workshop layout, workshop layout, and main equipment drawing. The F-1 Valve tower kind crude distillation tower be used. Plate number to 16, tower Drive1.51m , board spacing 0.4m. The F-1 Valve tower kind distillation tower be used. Plate number to 32, tower Drive 1.9 m , board spacing 0.45 m. The direct steam heating is used the bottom of the tower ,the concentration percent 0f the alcohol discharged from the tower top is 95%(mass fraction),directly sent into the reflux condenser for further purif
