| Cowpea dehulling is an important operation in the processing of cowpea. Traditional cowpea dehulling methods recognize the soaking of cowpea in water for a significant amount of time before manual abrasion is carried out either through the use of mortar and pestle, hands, or legs. Existing mechanical alternatives also require prolonged soaking of cowpea before dehulling occurs in addition to being expensive and beyond the reach of many rural populations. This study designed and fabricated a dry cowpea dehulling machine using engineering principles and with locally available materials. Components of the machine include the hopper, power transmission drive, dehulling chamber, polishing chamber, sieves, discharge chute, and agitator. Dry cowpea varieties of... |

| A multipurpose cabinet dryer was designed, constructed and tested using locally available materials. The system comprises a heating chamber, heat exchanger, drying trays, 3-phase blower, three heating elements of 1800 W each, and a control box, which consists of temperature control, contactor, thermocouple, and circuit breaker. The dryer was evaluated based on power consumed, moisture removal, drying rate, and drying efficiency. The result showed that the energy consumed when drying plantain chips, moringa leaves, okra, and locust beans are 346.55, 55.92, 110.63 and 49.64 kJ, respectively. The energy consumed increased with an increase in the moisture removed and drying time. Similarly, the drying rate for plantain chips, moringa leaves, okra, and locust... |
