同向双螺杆挤出植物蛋白肉过程特性研究Characteristic of co-rotating twin-screw extrusion process for plant-based protein meat
旨在采用湿法挤压组织化技术生产植物蛋白肉制品,以缓解动物蛋白的供应压力和保证人体需要的蛋白质来源。基于同向双螺杆挤压机制备高质量拉丝蛋白,测量了植物蛋白肉物料的流变特性,建立模型并采用ANSYS Fluent对挤压机内流场进行全过程数值模拟,并验证数值模拟的可靠性,以及分析了挤出过程中流道内压强、速度、温度、剪切速率和剪切应力等关键参数的变化规律。结果表明:挤压机出口流量、螺杆扭矩和机头压强都随着螺杆转速的增加而增大,试验值与模拟值相对误差较小,验证了数值模拟的有效性,但高螺杆转速下过高的剪切应力会降低植物蛋白肉成型质量,其中螺杆转速为290 r/min时产品品质最佳;在螺杆转速290 r/m...
