Title: Improving Maize Shelling Operation Using Motorized Mobile Shellers: A step towards Reducing Postharvest Losses in Low Developing Countries


Maize shelling is still a challenge in low developing countries with more efforts required to advance this operation. In Uganda, motorized immobile maize shellers have been fabricated locally to enhance the shelling operation. However, transportation of these maize shellers has remained a challenge and it imposes an extra cost to the farmers hence reducing their profits from maize growing. This study reviewed maize shelling operation in low developing countries with case studies of using mobile and immobile maize shellers. The study concluded that, on addition to other maize sheller performance attributes, motorized mobile maize shellers can solve the transport challenges associated with the motorized immobile maize shellers.


Denis Nsubuga is an early career scholar and currently finishing his Ph.D. in Department of Agricultural and Biosystems Engineering, Makerere University, Kampala, Uganda. He is also an Assistant Lecturer in the same department and a visiting academic in the school of chemical and metallurgical engineering, University of Witwatersrand, Johannesburg, South Africa. He is passionate about post-harvest engineering with a special focus on maize shelling. He has so far published 7 papers with 21 citations to date and he is peer reviewer for a number of reputable journals. Before joining the University as a staff, he worked with small holder farmers for 4 years and helped in building their capacity in the area of post-harvest engineering.
