摘要
基于流变学原理 ,确定了挤压米糠的表观黏度模型 ,并对模型进行了线性回归建模 ,以便进行试验拟合。试验研究了挤压米糠的流变特性 ,结果表明米糠的表观黏度随剪切速率的增加而减小 ,呈现出假塑性流体的流动行为 ;米糠的表观黏度随温度的升高和原料水分的增加而减小。
According to the theory of rheology, the apparent viscosity model of rice bran was established. Experiments were conducted to study the rheological property of rice bran, results showed that the apparent viscosity of rice bran decreased with increasing shear rate, exhibiting the rheological behavior of pseudoplastic fluid; that is the apparent viscosity of rice bran decreased with an increase in the temperature of the raw material; while the apparent viscosity of rice bran decreased with an increase in the moisture of the raw material. Equation of the apparent viscosity model was calculated by the computer.
