【摘要】 以大豆、大米、鸡肉、全脂乳粉为原料,按一定比例混合,采用Box-Behnken中心组合试验研究双螺杆挤压工艺参数。综合考察物料含水率、喂料速度、螺杆转速、温度对糊化度的影响,在此基础上对变量进行响应面分析,得出最佳挤压参数是:物料含水率23.32%,五区温度105℃,螺杆转速160r/min,喂料速度30r/min。更多还原

【Abstract】 The soybean-rice-chicken-whole milk powder mixture is used as raw materials.Box-Behnken experimental design combining with response surface metho-dology was employed to study the twin-screw extrusion process parameter conditions,including material moisture content、feeding speed、screw speed、the fifth district of barrel temperature on gelatinization degree.The best extruding condition is obtained:the moisture content is 23.32%,the fifth district of barrel temperature is 105 ℃,the screw speed is 160 r/min,the feeding speed is 30 r/min.更多还原
