Abstract: [Objective] The mold hole of the granular equipment of fresh giant fungus grass granules is one of the key components that determine the quality of the finished granular feed and the energy consumption of production, and the key parameters of the die hole need to be studied in order to improve the production efficiency. [Method] The experimental design method of DesignExpert BBD (Box-Behnken Design) was used to simulate the pressing process of the fresh giant fungus grass granular feed preparation equipment based on the nonlinear finite element software ABAQUS. [Result] The contribution rate of each factor is ranked as cone angle>cone depth>mold hole diameter. The optimal design parameter combination for the mold roller mold hole is 45° cone angle, 5 mm cone depth, and 6 mm mold hole diameter. [Conclusion] By using ABAQUS software to simulate the key components of the equipment for preparing fresh giant fungus grass granules, the optimal process combination of mold hole design parameters can be obtained, shortening the product design cycle, saving production costs, and providing a theoretical basis for related designs.
