纤维乙醇发酵醪流变特性研究

Rheological properties of fermented mash of cellulosic ethanol

为了探讨纤维乙醇发酵醪的流变特性,利用NDJ-79型旋转式黏度计对不同质量浓度的发酵醪在不同温度条件下的流变特性进行了测定分析。结果表明,纤维乙醇发酵醪为假塑性流体,其黏度随温度的升高而减小,随质量浓度的减小而减小。

In order to elucidate the rheological characteristics of fermented mash of cellulosic ethanol, NDJ-79 type rotary viscometer was employed at different mass concentrations of it and different temperatures. Results showed that： fermented mash of cellulosic ethanol is a pseudoplastic fluid, its viscosity decreases with the mass concentrations and the rising of temperatures.
