The need to find alternative method for drying wood due to erratic electric power
source necessitated the need to explore renewable energy source. Performance of solar kiln
drying and air-drying on Alstonia boonei and Brachystegia eurycoma wood was examined. Daily
temperature and relative humidity patterns in the two drying media were investigated to determine
the influence of the drying methods on the attainable moisture content of the selected wood after 21
days. Average daily temperature and relative humidity in the solar kiln dryer for the drying periods
were 39.83°C and 80% respectively while 28°C and 96% recorded for the air-drying shed. Higher
temperature was recorded for the solar kiln dryer than the air-drying shed. The final moisture
content for Alstonia boonei and Brachystegia eurycoma at the end of the 21 days of drying were
19.38% and 20.99% respectively. Statistical analysis showed that there was no significant difference
in the final moisture attained by the two wood species because they were dried in the same
compartment. However, there was significant difference in the interaction between the dryer and
the wood species.
