Nutmeg sheller, Peeling machine, Two –way ANOVA


The development peeling machine for nutmeg sheller peeling was to obtain a model of a peeling machine for community production and tested the efficacy of the peeling machine. At present, most of the peeling of nutmeg is done manually using knives. The prototype consisted of the chassis set, the rotation speed set, and the spinning cylinder peeling of nutmeg set. The experimental factors consisted of 4 speeds: 100, 150, 200 and 250 rpm and 4 peeling times: 2 4 6 and 8 min and the batch load was 10 kg, and amount of water used was 5 liters. The results showed that using the rotation speeds for peeling nutmeg sheller at 200 rpm and peeling time of 6 minutes got the weight of 9.33 kg, which was the highest weight of the nutmeg peeled in the experiment. When comparing the efficiency of peeling nutmeg sheller between human labor and machine, it was found that the machines more efficient than human labor at 84.15 percent. In addition, the statistical analysis found that the main factor had the same effect as the contributing factor on the weight of the nutmeg peeled at the significant level of 95% (gif.latex?\alpha ) = 0.05.
