Optimization of Operational Parameters of an Improved Maize Sheller Using Response Surface Methodology

The research was carried out to optimize parameters for evaluating an improved motorize maize sheller. Statistical analysis was performed using response surface methodology insert ignore into journalissuearticles values(RSM); with 3 by 3 factorial experiment with 3 replicates. The three parameters are speed insert ignore into journalissuearticles values(850 rpm, 950 rpm and 1100 rpm);, moisture content insert ignore into journalissuearticles values(12, 15, and 17%); and feed rate insert ignore into journalissuearticles values(120 kg h-1, 130 kg h-1 and 140 kg h-1); used to illustrate the ability of the machine to shell maize insert ignore into journalissuearticles values(throughput capacity, shelling rate and machine efficiency);. Results obtained showed that for optimum throughput capacity of 630.97 kg h-1; shelling rate 485.34 kg h-1 and machine efficiency 93.86% of the machine; is maximum for 129.6 kg h-1 feed rate and moisture content 16.49% and machine speed of 1026.9 rpm. The machine can be used on commercial farms with these operational results.
