Abstract A new straw processing equipment that integrates crushing, puffing, and granulation functions has been designed to address the issues of single-function, low efficiency, and high energy consumption in traditional straw processing equipment. By analyzing the advantages and disadvantages of different crushers, puffing devices, and granulation devices, the optimal combination of hammer-type crushers, segmented screw puffing devices, and ring die roller granulation devices was determined. Using SolidWorks and ANSYS, finite element analysis was conducted on the key component, the screw, to verify its structural strength and stability. The research findings indicate that this integrated equipment can efficiently perform straw crushing, puffing, and granulation, significantly enhancing the efficiency of straw feed utilization and providing technical support for the high-value utilization of straw resources.
