Performance optimization and economic analysis of oil palm broom processing machine

Abstract

The optimal performance and economic potentials of oil palm broom processing machine were examined in this study in order to ascertain its viability, adoption and commercialization. A Box-Behnken Response Surface Experimental design was used to investigate the optimal operational parameters and responses; while standard investment markers such as Payback Period, Accounting Rate of Return (ARR), Net Present Value (NPV) and Benefit cost Ratio (BCR) were evaluated to ascertain its sustainability and viability. The optimal peeling efficiency and throughput of this machine were determined as 94% and 6311 bristles/hr, respectively when operated at rotary peeler speed, stationary peeler arc length and peelers clearance of 536 rpm, 459 mm and 3.9 mm, respectively. Also, an annual initial sum of N 1,816,378.00 is required for start-up whereas average cash inflow of N 1,074,248.00 can be realized yearly. Payback period, Accounting Rate of Return, Net Present Value and Benefit Cost Ratio were also determined as 1.69, 7.89%, N 6,700,123.00, and 1.76, respectively. It can therefore be seen that this mechanized broom processing technology is profitable and thus recommended for both small and medium scales oil palm processors.
