Locust beans dehulling machine was design, develop, and evaluated. The machine was evaluated at different speed and boiling time for its performance efficiency. The results showed that with increase in the boiling time from the first to second hr the throughput capacity, qualitative, and quantitative dehulling efficiency increased but from the second to the fourth hr of boiling, it decreased. Whereas as the dehulling speed increase the throughput capacity increased but the quantitative and qualitative dehulling efficiency decreased. Highest throughput capacity and the least labor requirement were recorded at 1 hr boiling, whereas highest quantitative and qualitative dehulling efficiency was recorded at 2 hr of boiling. The boiling time and dehulling speed significantly affects the throughput capacity, quantitative and qualitative dehulling efficiencies of the dehuller, but does not affect labor requirement. The economic analysis reveals that developed dehuller can be useful for small to medium scale locust bean processing industries. PRACTICAL APPLICATIONS: The developed dehuller is relevant in the dehulling of boiled locust bean seed. This would, therefore, combat the challenges surrounding locust bean processing especially with the rural women dwellers and commercial producers. The dehuller would, therefore, reduce the time consumption and drudgery associated with the processing of locust bean.
