棉籽粉流变特性的研究
Rheological Properties of Cottonseed Meal
-
摘要: 用毛细管流变仪研究了棉籽粉的流变特性。实验结果表明:棉籽粉呈现很强的非牛顿性,剪切速率、温度和含水率对表观粘度影响显著;表观粘度随剪切速率的增大而减小,随温度的升高而减小,随含水率的增大而减小。文中还提出了棉籽粉的粘度模型和半经验公式。Abstract: The rheological properties of cottonseed meal were investigated using a capillary rheometry. The experimental results showed that the cottonseed meal was a typical pseudoplastic fluid in the normal processing ranges, and the apparent viscosity decreased with increasing shear rate, decreased with increasing temperature and decreased with increasing meal moisture. A model based on these results to predict the apparent viscosity of cottonseed meal was also presented.
