Abstract :

This study presents the development of a shelling efficiency prediction equation for a melon seed machine shelling process. Analytical approach of dimensional analysis was used in the prediction model development. The shelling rate model parameters of ; moisture content of melon seed, bulk density, feed rate, speed of shelling drum, shelling drum diameter and drum concave clearance of the machine were combined using pie terms theory to form both product and sum components equation of the prediction equations. The two component equations were subjected to evaluation test of bias and root mean square error to determine the appropriate model prediction equation while t-test was used for the significant level of the models developed. Developed prediction equation was validated using sufficient data from extensive testing operation of the shelling machine. A comparison of predicted and experimental data of the machine shelling efficiency showed a good fit with value of coefficient of determination as 0.86.
