Cracking of dika nut has presented serious challenges to local processors considering the arduous task it constitutes during processing. A motorized machine that is capable of multiple cracking of dika nuts was designed, fabricated and tested. The major components of the machine include a sliding hammer, a gear unit, a chain conveyor and cracking trays. The experimental machine was evaluated on the basis of cracking efficiency and throughput considering three types of pre-treated nuts (sun-dried, oven-dried and roasted) and two nut sizes (small and big). The cracking efficiency and throughput were: 65% and 8.84kg/h, 63% and 7.75kg/h, 45% and 5.67 kg/h for roasted, oven-dried and sun-dried small nuts; while the corresponding values for big nuts were: 72%... |

This paper aims to analyse the direct energy utilization in the processing of cocoa beans into powder using energy from the national grid and diesel engine in some cocoa processing factories located in South-western Nigeria. Energy consumption in the processing of cocoa beans into powder was evaluated for the eight major unit operations that cocoa processing entails, namely: cleaning, roasting, winnowing, milling, alkalizing, pressing, butter packing and grinding/sieving. The data obtained were imputed into existing energy equation to estimate the energy requirement for each of the eight unit operations. The results show that total energy expenditure in the processing of raw cocoa bean into powder were 1.815 and 2.384 MJ/Kg using national grid (PHCN) and... |

This paper is an appraisal of Agricultural Engineering education in the quest for manpower to drive the agricultural transformation agenda in Nigeria. It takes a critical look at Agricultural Engineering training especially in Nigerian Universities, focusing on curriculum changes, institutional capacity for manpower development and training, succession plan and post graduate training vis-à-vis modern trends around the world. Among twenty seven (27) institutions presently offering Agricultural Engineering in Nigeria, ten (10) were established after year 2000 and do not have post graduate training program. The survey show that 31.6, 28.7, 11.8 and 27.9% of the academic staff are in the area of farm power and machinery, crop processing and storage, farm... |

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... |
