An electrically operated cotton seed delinting machine was optimized and its performance was evaluated. The machine was modified by introducing three pulleys with diameters as 250mm, 200mm and 120mm, which produced rotor speeds of 550rpm, 600rpm and 650rpm respectively. The rotor speeds were then used to test the designed machine and its efficiency were evaluated. The belt and pulley were used to transmit power from the electric motor to the shaft of the cotton seed delinting machine unit. The designed machine was operated by a 2hp electric motor. The performance test was carried out using three different feed rates at three different speeds which include 550rpm, 600rpm and 650rpm, using 5g, 6g and 7g weight of feed rates of the cotton wool with their seeds. Each one was replicated five times. The results showed that the efficiency of the machine was high at 7g feed rate, which was 79.93% and the speed does not influence the efficiency of the machine. The statistical analysis [ANOVA] for the effect of speed of the rotor and feed rate on the capacity and performance of the evaluated machine at 5% probability level was computed. The result of the analysis confirms that feed rate was significant processing parameter that affects machine efficiency.
