A small-scale maize harvester was designed and fabricated for developing countries and is composed of a harvester header, a chain conveyor, a drive power unit and a five-wheel tricycle. Fabrication of components was made and assembling of the devices on the tricycle was done. The performance evaluation of the small-scale maize harvester was done at 15% kernels moisture content (wet basis). Three rotational speeds of the engine, 1347, 1521 and 1937 rpm were used, while the forward velocity of the harvester was kept at an average of 0.617 km.hr-1. The testing experiment revealed significant effect of physical properties of maize (p<0,05). The highest machine capacity was obtained at 0.05 ha.hr-1, while the highest driving efficiency was 97.30% and the highest picking and conveying efficiencies were 84.11% and 98.21%, respectively. However, it was observed that the machine noise level decreased with increase in engine speed. Also, the engine speed affected both picking and conveying efficiencies. The designed machine is found suitable for most smallholder farms.

Potato Peeling

An Irish potato peeling machine was developed for use at small-scale/household level. Machine performance evaluation was carried out using three locally grown Irish potato varieties namely; Nicola, Bartita and Bawondoya respectively. A 22x3 factorial experiment in completely randomized design (CRD) with three replications was used for evaluation where tuber feed rate, shaft speed and variety were the independent variables and peeling efficiency, tuber flesh loss and machine output capacity were the performance indicators. Analysis of variance (ANOVA) results showed the effects of variety on peeling efficiency and feed rate on output capacity as highly significant (P=.01). Also, the interaction of speed and variety on peeling efficiency and the effect of variety on output capacity was significant (P=.05). The interaction of variety and speed at 480 rpm achieved a maximum mean peeling efficiency of 55.6% for Bawondoya. Similarly, at slightly higher speed of 510 rpm, the maximum mean peeling efficiency of 64.6% was achieved for Bartita. Flesh loss value of 0.84% was the least obtained and this was for Bartita while the highest flesh loss of 1.43% was observed for Nicola. At feed rates of 50 g/sec and 60 g/sec; the minimum and maximum output capacities of 31.3 kg/h and 59.2 kg/h were obtained respectively.

And Performance

The importance of heat energy source from wood to humanity cannot be over emphasised since many depend on it for their heating needs. In this work, a wood stove was designed, constructed and tested without a skirt and with a detachable skirt of height 120 mm (same height as the pot used for the experiment) to ascertain the influence of the skirt on the stove in terms of thermal performance in a water boiling test. Thermal efficiency and specific fuel consumption were evaluated. It was found that the stove tested without a skirt gave an average thermal efficiency of 31.33% and an average specific fuel consumption of 0.14 kg/l. When tested with a skirt, however, the stove gave an average thermal efficiency of 38.65% and an average specific fuel consumption of 0.09 kg/l. This signifies an improvement in thermal performance by the use of skirt on the stove designed. Keywords: Humanity, Globally, Detachable-skirt, Thermal performance, Wood stove.
