摘要
探讨了挤压机模孔直径、螺杆转速、螺杆螺距和含水率等挤压系统参数对蛋白质消化率的影响规律。试验结果表明,膨化机模孔直径为15mm、螺杆转速为225r/min、螺杆螺距为32mm、血粉的含水率为21%时,膨化血粉蛋白质消化率较高。
The principle of the influence of parameters of extrusion system, including the diameter of the Die diameter, the Screw speed, the Screw pitch, Moisture content on the NSI of the blood meals was discussed in this paper. The regularity of the digestibility of expanding blood meals by single factor experimentation showed： die diameter 15mm, screw speed 225r/min, screw pitch 32mm and Water content 21% could get the highest blood meals protein digestibility percentage.
