Development of an active evaporative cooling system for short-term storage of fruits and vegetable in a tropical climate CIGR Journal
Chinenye, Ndukwu Macmanus; Manuwa, S. I.; Olukunle, O. J.; Oluwalana, I. B..
An active evaporative cooler for short-term storage of fruits and vegetable has been developed to improve the shelf life of fruits and vegetables for small holder farmers in Southern Nigeria.  The evaporative cooler uses palm fruit fiber as cooling pad material which is considered a waste in palm oil production in Nigeria and consists of three suction fan, automatic water control switch, water pump and evaporative cooling chambers.  The performance of cooler was evaluated in terms of temperature drop, efficiency of the evaporative cooling and cooling capacity.  The temperature drop ranged from 40C to 130C while the relative humidity of the ambient air was increased to 96.8%.  The cooler could drop the temperature close to wet bulb depression of ambient air...

Nigeria’s grain resource structure and government sustainable policy: a review CIGR Journal
Chinenye, Ndukwu Macmanus.
Nigeria is rich in several food grain resources that empower the country with a large capacity to develop a food-grain policy. The current food-grain resource structure of Nigeria is reviewed in terms of production, milling, storage structure and issues confronting the sector growth, sustainability, policies and frameworks towards the actualization of food production efficiency. Total food-grain consumption (wheat, maize, sorghum and rice) decreased by 1.2 Mt in 2011-2013. Local consumption of wheat, and rice marginally increased by 191,000 and 500,000 t respectively in 2011-2013, that of maize and sorghum decreased by 1.5 Mt and 350,000 t respectively at the same period. About 76% of the total food grain consumption was produced locally in 2011/2012 while...
