| 摘 要： | 本文研究了以荞麦、黑米、薏米三种谷物的混合物料为原料时，双螺杆挤压机的螺杆转速，物料湿度、机筒温度三种操作参数对双螺杆挤压机的功率消耗(以单耗衡量)的影响。依据可旋转中心组合实验设计及实验数据建立了相关的统计模型，通过对响应面和等高线的分析，得出了三种操作参数的最佳取值范围。本研究对于开发谷物膨化食品、探索双螺杆挤压机加工谷物原料的挤压机理具有重要的现实意义。

| Abstract: | Using compound raw material comprised of buckwheat,melan-rice and coix-maize,the effects of screw speed,barrel temperature and mash moisture on expansion quality (expressed as dextrinization degree) and energy expenditure in twin-screw extrution were studied.A statistical mode was build up using a rotate central composite design and response surface methodology.The optimum range of operational parameters were resulted by triaxial contour map and isohypse analysis. |
