| Abstract | The objective of this research was to study the design factors of the axial-flow corn shelling unit affecting losses andpower consumption. The shelling unit was 0.90 m long with a diameter towards the end of the peg tooth of 0.30 m. Designfactors comprised of five levels of peg tooth clearance (PC), 25.4, 50.8, 76.2, 101.6, and 127.0 mm, five levels of concave rodclearance (CR), 15, 20, 25, 30, and 35 mm, and five levels of concave clearance (CC), 10, 15, 20, 25, and 30 mm. The experimentswere conducted based on response surface methodology and central composite design. The results of this study show thatPC, CR, and CC were found to have significant impact on the shelling unit loss and power consumption, but not on grainbreakage. Increase in PC and CC or decrease in CR had a trend to increase shelling unit loss. Increase in PC, CR, and CCresulted in less power consumption. Empirical models were constructed based on multiple linear models to define thebehavior of the shelling unit loss and power consumption, with R2 of 0.92 and 0.72, respectively. |
