Abstract


The performance of a Cassava Attrition peeling Machine was quantified and optimized using response surface methodology with  mass, Mc moisture content, MC geometric mean diameter, Dg, peel thickness, Pth of cassava tubers; number of peeling balls, nb and peeling drum speed, Nd as factors investigated while flesh loss, peeling efficiency and throughput constitute the response variables. The experimental plan used was based on standard central composite RSM design, with a half factorial portion in which all combination of factors were at two levels. The results of the performance analyses revealed that the machine operates optimally with a throughput of 180.71kg/h, efficiency of 88.7% and 5.4% flesh loss at the determined optimal speed of the peeling drum (Nd), moisture content of the cassava(MC), mass of loaded cassava (Mc), number of peeling balls (nb), average geometric mean diameter of the cassava tubers (Dg) and the mean peel thickness of the cassava (Pth) of 45rpm, 85% 82kg, 134, 48mm and 4.13mm respectively. These results improved the machine by over 60% of its throughput and 17.64% efficiency at the optimal settings of the operational parameters. The results further showed that the main effects of all the factors provided significant influence on the responses with the exception of geometric mean diameter on efficiency (hence elimination of preoperational treatment) while the factor interactions provided secondary influence. Confirmatory test of the developed RSM models revealed over 95% prediction accuracy.
