针对鱼类原料水射流式去鳞设备射流参数不合理、准确性差、去鳞效率低下等问题,本文建立了鲤鱼模型并利用Fluent软件对水射流式鱼体去鳞进行了仿真模拟,建立了鱼体去鳞的力学性能评判指标,分析了射流压力、射流靶距和射流入射角的变化对鱼体去鳞的力学性能评判指标影响趋势,结果表明,在试验给定射流参数范围内,当射流压力9 MPa,射流入射角20˚,射流靶距100 mm,此时受力均匀性、有效打击比和最大打击力最优,为鱼类原料水射流式去鳞设备提供理论方法和技术支持。
Aiming at the problems of unreasonable jet parameters, poor accuracy, and low descaling efficiency of fish raw material water jet descaling equipment, this paper established a carp model, and simulated the water jet descaling using fluent software, and established the mechanical per-formance evaluation index of fish body descaling. The influence trend of the changes of jet pressure, jet target distance and jet incident angle on the mechanical performance evaluation index of fish body descaling is analyzed. The results show that within the given jet parameter range of the test, when the optimal jet parameters of scales are jet pressure 9 MPa, jet incidence angle 20˚, and jet target distance 100 mm;at this time the uniformity of force, effective strike ratio and maximum strike force are the best, which provided theoretical methods and technical support for fish raw water jet descaling equipment.
