摘 要: 对食品双螺杆挤压机的操作参数与挤出过程及谷物产品特性之间的关系作了试验研究。通过改变螺杆转速、进料速率这两个变化因素,研究模头压力、模头处物料温度、主机电流、产品膨化度、产品水溶性指数、产品吸水性指数等指标的变化规律,建立有关数学模型并进行分析。 This paper teports the study into the relationship between operation parameters and extrusion process as well as corn product chararcteristics in the twin screw extruder. We changed two varaiables-screw speed and feed rate to study die pressure,product temperature in the die,motor electric current,product expansion ratio,product water solution index and product water absorption index. After analysing experiment datas,we got some formulas and attampt to explain these regulations.
