摘　　要：设计一款快速生产面鱼的食品挤压机,对物料在挤出端结构中的挤出过程进行分析和模拟。首先采用三维绘图软件绘制零部件和总体装配三维模型,将待仿真的三维模型导入有限元Workbench Fluent分析模块中,随后将待仿真三维模型定义为非牛顿流体,此外设定流体域的输料口的进料速度与出料端压力,最后使用方差试验得到9组挤出端装置的较优结构组合。通过构建以上9种装置以模拟流道内速度场的物料流动情况,选取最优评价指标及挤出端装置的最优组合结构。最终确定挤出端装置为SN4型结构,分析表明使用该结构生产的面鱼生产效率较高。This paper designs a food extruder for the rapid production of noodle fish,analyzes and simulates the extrusion process of the material in the extrusion end structure.The 3D drawing software is used to draw the parts and the overall assembly 3D model,the 3D model to be simulated is imported into the finite element Workbench Fluent analysis module,and then the 3D model to be simulated is defined as a non-Newtonian fluid,and the feed speed and outlet pressure of the inlet of the fluid domain are set.The variance test is used to obtain the optimal structural combination of nine sets of extrusion end devices.By constructing the above nine devices to simulate the material flow of the velocity field in the runner,the optimal evaluation index and the optimal combination structure of the extrusion end device are selected.The extrusion end device is finally determined to be an SN4 type structure,and the analysis shows that the production efficiency of noodle fish produced using this structure is higher.
