摘  要:
研究了玉米秸秆水解过程中球磨预处理工艺的优化,采用Plackett-Burman(PB)试验设计和均匀试验设计法,用数据处理软件对试验结果进行分析,筛选出了球磨预处理过程中的主要影响因素,得到了具有较好拟合度的回归方程;通过分析原料粒径(mm),转速(r/min),原料填装量(g),研磨介质,交替时间(min)等球磨条件对酶解效率的影响,得出行星式球磨机粉碎玉米秸秆的最佳工艺参数为:原料粒径0.5mm,转速340r/min,原料填装量3.4g,装球量15个(Ф=10.0mm),交替运行时间5min。

摘  要:
Plackett-Burman(PB)experimental design and the uniform experimental design were used to select the main factors of the ball milling pretreatment of corn stalk.The experimental results were analyzed by data processing software and well-fitted regression equation was established.Effects of ball milling parameters,such as raw material diameter,speed,ratio of raw materials,grinding media and alternating time,on the enzymolysis were analyzed.The optimal parameters of ball milling pretreatment of the corn stalk were as follows: particle size of raw material of 0.5 mm,speed of 340 r/min,the raw material content of 3.4 g,the number of ball of 15(Ф=10.0 mm), alternating running time of 5 min.
