Performance Evaluation of a Hybrid Dryer for Grains

Nathaniel Oji, S. A. Okaiyeto & Pwajok Nyam · Journal of Engineering Research and Reports · 2025

The study evaluated a hybrid grain dryer prototype at Ahmadu Bello University, Zaria, Nigeria, in May 2019, focusing on air flow rate (3.6, 4.5, 6.1 m³/s) and grain depth (5, 10, 20 cm) as key factors. A 3×3 factorial experiment in a randomized design assessed the dryer's perform...

Thin Layer Modelling of Indirect and Mixed-Mode on-Farm Drying of Selected Vegetables

Nathaniel Oji, S. A. Okaiyeto & Y. A. Unguwanrimi · Asian Food Science Journal · 2022

The thin layer drying characteristics of tomato and okra slices dried using mixed-mode on-farm solar dryer, indirect mode on-farm solar dryer and open sun drying. The tomato and okra slices dried faster when dried under the mixed-mode on-farm solar dryer. Drying time was reduced...
