| description | Poor shelling quality degrades the performance and profit of the peanut industry. The Hertz theory and the wear resistance experimental method were applied to identify a highly wear-resistant material guaranteeing a low mechanical damage rate (MDR) of peanut kernels. The Box–Behnken design method was applied in the experiment to illustrate the influence of the material’s elastic modulus (<i>X</i><sub>1</sub>), radius of curvature of the key parts (<i>X</i><sub>2</sub>), rotating speed of the shelling drum (<i>X</i><sub>3</sub>), and clearance between the shelling drum and concave screen (<i>X</i><sub>4</sub>) on MDR and shelling efficiency (SE). Depending on the analysis of variance, the weights of the influential factors were observed as <i>X</i><sub>1</sub> > <i>X</i><sub>3</sub> > <i>X</i><sub>4</sub> > <i>X</i><sub>2</sub>. The mathematical models of MDR and SE were derived from the least squares’ method, and four-dimensional slice diagrams of the three most significant factors were used to illustrate the trends of MDR and SE. A multi-objective analysis provided the optimal combination of parameters as: <i>X</i><sub>1</sub> = 10 MPa, <i>X</i><sub>2</sub> = 12.77 mm, <i>X</i><sub>3</sub> = 277.48 r/min, and <i>X</i><sub>4</sub> = 24.24 mm, yielding MDR = 4.89% and SE = 97.91%. The results were further verified by a production trial test, proving that the proposed solution with the selected material, machine design, and working parameters were effective in improving peanut shelling quality. |
