Abstract :

Design modifications were carried out on an existing melon (Citrullus lanatus) depodding machine. The existing machine can adequately depod melon but it had no mechanism for separating seeds and the pulp to obtain clean seeds. The modifications made include; the incorporation of water showering system, which represents the mechanism of seeds removal from depodded pulp; the incorporation of a reciprocating sieve (cleaning system), which removes unwanted material from clean seeds; and the addition of seed guard system, which influences the flow of seeds directly into the reciprocating sieve (cleaner). The performance evaluation of the machine was carried out on three different melon treatments i.e. freshly sliced pods, fresh and unsliced pods, and fermented pods. The performance evaluation of the machine was conducted under five different pulley speeds i.e. 229 rpm, 187 rpm, 163 rpm, 150 rpm and 122 rpm, in a 5 x 3 factorial experiment which was replicated 3 times. Results of the performance evaluation of the modified machine indicated significant improvement over the existing one. There was reduction in clean seeds output with reduced speed of the machine for the sliced, unsliced and fermented pods respectively. The maximum overall efficiencies on the basis of the considered operating speeds of the machine are 89.2, 77.4 and 93.4% for the sliced, unsliced and fermented pods, respectively. The difference in overall machine efficiency at speeds of 229, 150 and 122 rpm is significant at P = 0.05 but not significant at speeds 187 and 163 rpm. The highest depodding efficiency (98% at 229 rpm speed) was observed while the machine worked on fermented pods. Seed discharge efficiency on the basis of the considered operating speed varies linearly with machine speed and was highest (91.3%) on fermented pods at speed of 229 rpm, while the highest mean discharge efficiency on sliced pod was 85.0% at speed 229 rpm.
