| 摘 要： | 研究了蒸汽爆碎处理甘蔗叶提取木糖过程中爆碎压力、维压时间对木糖溶出量的影响:木糖溶出量随爆碎压力增加而增加,随维压时间增加,先增大后减小,随粒度增大而减小,随固液比增大先减小后增大。并采用响应面实验和DesignExpert7.0软件分析实验设计拟合得到的模型较好地符合实际,并得到最佳爆碎工艺为:爆碎压力1.1MPa,维压时间12.5min,粒度100目,液料比15∶1(v/w),蒸汽爆碎是一种很好的甘蔗叶提取木糖的预处理方式。

| Abstract: | The steam explosion affected the production of xylose from sugar cane leaves by vitriol.In this paper,two primary factors:the pressure,the time of keeping pressure were studied.Firstly,when the pressure raised,the content of the xylose increased;when the time of keeping raised,it increased firstly,then reduced;when the granularity got large,it became reduce;when the proportion of the sugar cane leaves to water became increase,it became reduce and then increased.A mode was also got according to the practice ... |
