Experimental Study on the Peeling Fracture Effect of Fresh Corn Ear Based on High and Low Roller Peeling Equipment

Aiming to address the problems of low working efficiency and high damage rate roller peeling equipment in process fresh corn harvesting China, this paper theoretically analyzes mechanical motion between device ear, a high–low roll structure is proposed. This incorporates elastomeric rubber material, segmentation design, an adjustable spiral frame, selection relevant parameters given. To determine optimal operating for fresh-corn-peeling device, three-factor, three-level orthogonal test was conducted using Box–Behnken central grouping method Design-Expert 12 software. The factors were speed, tilt angle, vibrating plate frequency. evaluation indices considered bract (BPR) grain breaking (GBR). Based on theoretical analysis results, bench fresh-corn-ear-peeling established parameter combination quality determined according actual work situation. results show that impact BPR GBR, from large small, following order: frequency vibration plate. optimization module used optimize integers obtain combination: speed 480 r·min−1; angle 8°; 260 times·min−1; corresponding 91.75%, which 0.66% points lower than value; GBR 1.55%, 0.08% higher value. Notably, exhibited superior performance terms fracture compared with standard equipment. Therefore, study provides valuable technical support design
