Abstract

To address the issue of high damage rates during the operation of peanut shelling machines, a low-damage peanut sheller was designed. This machine effectively reduces damage while improving shelling efficiency. The mechanism and working principles of the device are elaborated, and the critical shelling components are designed based on theoretical and mechanical analysis. The shelling process was simulated using Edem simulation software. Additionally, a quadratic orthogonal composite design experiment was developed using Design Expert to determine the optimal parameters. The final configuration, with a primary shelling drum speed of 302 r/min, a primary concave sieve gap of 10 mm, and a secondary concave sieve gap of 8 mm, achieved a shelling efficiency of 98.28% and a pod damage rate of 4.93%, outperforming industry standards. Field tests showed minimal discrepancy between experimental and simulation results.
