Abstract: To optimize the design of the hulling chamber structure in rubber-roller paddy hullers and reduce broken rice rate during hulling processing, this study takes a rubber-roller paddy huller as the research object.First, experiments were designed and conducted to analyse the temperature and airflow distribution within the hulling chamber.Second, numerical simulations of the temperature field and flow field inside the hulling chamber were performed based on fluid dynamics principles.Subsequently, comparative analysis between numerical simulation results and experimental data was conducted to validate the turbulence model, mesh generation, and boundary condition settings.This verification ensures the accuracy and rationality of the numerical simulation methodology for temperature and flow fields.The comparative results demonstrate temperature errors within 13.5 % and velocity vector errors within 15 %, confirming the feasibility and rationality of the proposed numerical simulation approach for temperature and flow field analysis.
