摘　　要：为了优化提高可调五辊式对虾剥壳的作业质量和效率,以70～80只/kg的南美白对虾为试验对象,利用研制的可调五辊式对虾剥壳机进行试验,以辊组转速、辊组转角、辊组V角、辊组倾角为影响因素,以剥壳率、得仁率、剥壳时间为评价指标,进行了四因素五水平正交旋转中心组合优化试验。通过Design-Expert 8.0.5b软件,建立了评价指标与各影响因素的数学回归模型,分析了显著因素对评价指标的影响,确定了最优参数组合为：辊组转速25 r/min,辊组转角315°,辊组V角130°,辊组倾角18°。选取鲜活对虾在-30℃温度下冷冻10 min进行预处理,并进行对虾去头、开背6节处理后进行剥壳试验,试验结果表明：在优化参数组合下,剥壳率平均值为94.67%,得仁率为85.23%,30只/组剥壳时间为54.33 s。试验表明可调五辊式对虾剥壳机满足对虾剥壳的技术要求,调节方便可靠,可为各个级别对虾剥壳装备的设计提供参数依据。There is enormous quantity of shrimp in China and it has great value of development and utilization. The peeling of the shrimp is mainly by manual labor at present, and the mechanized peeling technology of shrimp in China is still on a preliminary stage. Mechanical manipulation methods are being studied to improve the production efficiency and to extract the integral meat of shrimp. Shrimp processing time is relatively concentrated and labor resources are in shortage, which can not meet the needs of large- scale production of enterprises. Therefore the research of shrimp mechanical peeling has important significance and solving the problem of shrimp peeling mechanization is an important direction of development. Preliminary study results show that the method of roll- type extrusion peeling is good.Comparing the effects of dual-roller extrusion peeling and five-roller extrusion peeling, the peeling device with 5 rollers had the advantage of high peeling efficiency, so it would be widely applied for peeling shrimp. In order to further study the shrimp peeling machine and improve the work quality for the shrimp peeling machine, the adjustable five rollers peeling machine was designed. The study took the fresh Litopenaeus vannamei with a number between 70 and 80 per kilogram as the study object. In order to determine the operation parameters of the adjustable five rollers peeling machine, the response surface experiment with 4 factors and 5 levels was completed on the adjustable five rollers peeling machine. Four parameters, including rollers speed, rollers rotation angle, rollers V angle and rollers tilt angle were selected as the input variables, and peeling rate, meat yield and peeling time were selected as the output parameters. Quadratic orthogonal rotary regressive experimental design was employed to develop the second order polynomial regression model, which explained the relationship between the input and output parameters. By the DesignExpert 8.0.5b software, the corresponding mathematical regression model w
