ABSTRACT

The performance evaluation of a power operated stationary maize dehusker sheller at the Institute for Agricultural Research, IAR, Ahmadu Bello University, Zaria was conducted in order to develop an optimization mathematical model. The experiment was set in a factorial design involving four variables each at three levels; the layout was in a completely randomized block design (3x3x3x3= 81 treatments) and replicated three times. The analysis of the data was carried out using the SAS statistical package.. Duncan’s multiple range tests were used to compare the differences between significant means for variables .Best performance was obtained with speed, feed rate, concave clearance and Moisture content of 950 rpm, 40 kg/min, 35 mm and 9 % respectively. The performance indices shelling efficiency, Output capacity, cleaning efficiency, grain damage and scatter loss obtained at this combination were 99.45 %, 882.05 kg/h, 94.08 %, 6.37 %  and 15.00 %, respectively.


Keywords: cylinder speed, feed rate, shelling efficiency, grain damage, concave clearance.
