Résumé ou Introduction
This paper investigated the significant effects of the identified variables (input capacity, blower air velocity and the shelling cylinder shaft rotation) on the shelling recovery process of mungbeans to lessen the impurities and mechanical damages of kernels. This study utilized response surface methodology through Box-Behnken design as a tool to identify the effect of the identified variables to the response variable using the Minitab 17 software. It also aimed to establish the optimum values of the identified variables and the response variable. Based on the assessment from the fifteen (15) experimental runs, it was identified that the three identified variables are considerably significant to the shelling recovery of the mungbeans. Moreover, the optimal conditions of the independent variables, input capacity, blower air velocity and shelling cylinder shaft rotation are 40 kg/hr, 3.3536 m/seconds and 343 revolution per minute, respectively. These optimum values could predict an optimum shelling recovery of 96.9691%. This means an increase of the weight of cleaned kernels, decrease in impurities and the total losses (blower loss, scattering loss, unshelled loss and the separation loss) as well. The computed optimum values for input capacity and shelling cylinder shaft rotation are the medium level values and only the blower air velocity values are to be changed to produce optimum shelling recovery. It is lesser than the medium level (4 m/sec) therefore it is recommended redesign of the blower’s shaft rotation to decrease its air velocity. The study is delimited in the verification of those values in the actual set-up.
