中文摘要: 以混合食用菌菌糠为原料,以菌糠粗纤维降解率作为评价参数,采用边心响应面设计(Box-Behnken Design, BBD),考察食用菌菌糠双螺杆挤压膨化中 4 个重要因素,并优化菌糠双螺杆挤压膨化工艺。结果表明,混合食用菌菌 糠修正后最佳挤压膨化工艺条件为:菌糠水分含量 30 %,机筒温度 160 ℃,螺杆转速为 125 r/min,进料速度 100 kg/h, 在此工艺条件下,食用菌菌糠的粗纤维降解率平均为(40.86±0.18)%。

Abstract:The Double-screw extrusion technology of spent edible fungi substrate (SMS) has been studied and optimized though four facters Box-Behnken design (BBD) of response surface method (RSM),as index by curde fiber degradability. The optimal technology condition were material moisture of SMS 30 %, extrusion tem- perature 160 ℃, screw speed 125 r/min and feeding speed 100 kg/h, the crude fiber degradability of mixture SMS could reach up(40.86±0.18)% under this extrusion technology condition.
