The key parts of the design are the technologic calculation of rectifier in rectification workshop and the selection of type of its assistant equipment. The design includes two parts : instruction and blueprint. The instruction mainly includes the method of the extract of dioscin and the process flow。 the instruction of plane arrangement of the whole plant 。 design of nontechnology parts： the project of water supply, heating, draught, lighting, safety, sanitation, antisepsis, the disposal of pollution, environmental protection, the economic guidelines of technique. The main parts of the instruction are technologic calculation of the rectifier in rectification workshop and the selection of type of its assistant equipment , and in these parts , material balance and heat balance calculation and lots of experiential formulas are used as references. Blueprints include production flow chart, ichnography of the whole plant , ichnography of the rectification workshop ,the solid blueprint of the rectification workshop , the blueprint of structure of the rectifier. KEY WORDS: disogenin, design of rectifier， design of rectification ， design of technology III 目 錄 摘要 ?????????????????????????????????? Ⅰ ABSTRACT ????????????????????????????????
