【摘要】 为了探讨小麦淀粉浆糖化醪在加热过程中的流变特性,利用NDJ—79型旋转式粘度计对小麦淀粉糖化醪进行了流变性测定,并对其流变特性进行了分析.结果表明:小麦淀粉浆糖化醪是假塑性非牛顿流体,其流变特性服从幂律指数模型,随着温度的升高其稠度系数k减小,流变指数n基本上没有变化,随着浓度的增大其稠度系数k增大,流变指数n减小.更多还原

【Abstract】 In order to inquire into the rheological characteristics of wheat starch saccharification liquor heated, in this paper, the rheological characteristics of wheat starch saccharification liquor were measured by NDJ-79 type viscosity meter. The rheological characteristics of this kind of liquor was also analyzed .The results show that the liquor is pseudoplastic non-Newtonian fluid and its rheological characteristics meet with power-law index model. Its consistency coefficient K decreases with the increase of temperature, but the flow behavior index n changes little. With the increasing of mass ratio, the coefficient K increases, but the index n decreases.更多还原
