中文摘要：
为了降低去脏过程中鱼肉损伤，增加内脏去除率，优化去脏机剖切及去脏机构的技术参数，利用自制的小杂鱼去脏试验平台，以竹筴鱼和深水红娘鱼为试验对象，应用二次回归通用旋转组合试验设计，研究了传送带线速度、剖切刀转速和去脏轮转速与小杂鱼去脏后可接受性评分之间的关系，建立了去脏后可接受性评分同剖切及去脏机构技术参数间的数学模型。通过对拟合方程求极值，得出适合竹筴鱼去脏最佳参数组合为：传送带线速度为1.92 m/s、剖切刀转速为1154.0 r/min、去脏轮转速为60.0 r/min；适合深水红娘鱼去脏最佳参数组合为：传送带线速度1.39 m/s、剖切刀转速1280.0 r/min、去脏轮转速为95.0 r/min；在此条件下可达到可接受性评分的预测最大值，同时也能满足去脏加工的工艺要求。
英文摘要：
A self-developed gutted mechanism were employed for cutting Trachurus japonicus and Synodus macrops to avoid fish damage and increase gut removal rate in gutted process. The relationships of acceptability evaluation with transmission speed, cut knife rotation speed and gutted wheel rotation speed were studied by quadratic regression rotational combination design, and the mathematical model between the acceptability evaluation and operating parameters was established. The best parameters of gutted process of Trachurus japonicus were： transmission speed 1.92 m/s, cut knife rotation speed 1154.0 r/min,and gutted wheel rotation speed 60.0 r/min. And the optimized parameters for Synodus macrops were： transmission speed 1.39 m/s, cut knife rotation speed 1280.0 r/min, and gutted wheel rotation speed 95.0 r/min. Under these conditions the maximum value for acceptability evaluation of gutted effect was achieved.
