Abstract

This study aims to evaluate the performance of the AMDP cassava (Manihot esculenta L.) granulator and establish its optimum working conditions. An average %MCwb of 60.80%, 57.02%, 55.45% for 0, 2, and 4 days after harvest (DAH), respectively were obtained. The material balance showed a 73-76% granulated weight of the cassava. Fifteen experimental runs were done using the Design Number 1 of Box and Behnken experimental design to determine the optimum working condition of the machine and to know the effect of the independent parameters (DAH, days, blade clearance, mm, and drum speed, rpm) to the response variables (capacity, kg/h, percent granulated size < 12.7 mm, %, and power consumption, W-h ). The data generated were subjected to statistical analysis at 95% confidence level and were analyzed using Response Surface Methodology through Statistical Analysis System and Statistica v7. Results showed that blade clearance has insignificant effect on the response variables while DAH and drum speed have significant effects. The machine optimum working conditions were: 2 DAH, 16-mm blade clearance, and 900 rpm drum speed with 1076.10 kg/h capacity, 76.57% granulated size <12.7mm, and 25.30 W-h power consumption. Predicting equations were derived for the response variables and were compared to actual values through a verification run which gave insignificant differences. This means that the derived equation can predict the machine performance.
