The performance evaluation of a maize roasting machine was carried out with the aim of achieving efficient roasting of maize kernel. The performance evaluation of the machine was carried out using maize purchased at Ejigbo market in Osun State as sample. The machine was tested with 1000 g of peeled and unpeeled maize with three different temperatures of 200, 300 and 350C and four different speeds of 6.6, 15 and 19 rpm, respectively. The machine optimum functional efficiency was recorded for peeled and unpeeled maize at a temperature of 200C and the speed of 6.6 rpm which were 76 and 80.9%, respectively. Also, the machine optimum conveyance efficiency recorded for both peeled and unpeeled maize were 76.84 and 81.4%, respectively at a temperature of 200C and the speed of 6.6 rpm. Hence, the two evaluation parameters: speed and temperature have significant effect on the performance of the machine. The experiment shows that as the temperature increases, the conveyance efficiency decreases due to linear expansivity of the metal. The temperature of 200C with the speed of 6.6 rpm shows the optimum performance of the machine.



Key words: Performance evaluation, maize, roasting machine, throughput capacity, conveyance efficiency, roasting efficiency, temperature and speed.
