Title: Temperature Variations within Wooden and Metal Grain Silos in the Tropics during Storage of Maize (Zea Mays)
Abstract: The study was carried out on the comparative analysis of temperature variation within wooden and metal grain silos under a typical tropical weather condition in Nigeria. Temperature variations within and outside the silos were monitored for 130days (July to November) during storage of maize. Results showed that the grain temperature at the centre of the silos ranged between 24.0-32.7°C and 23.8-35.0°C for wooden and metal silos respectively. Also, at the silo walls, grain temperatures ranged between 24.5-35.8°C and 24.0-34.7°C respectively. The standard error of estimate between the results of the silos at the centres and walls were 1.65°C and 1.16°C respectively. The temperatures at the top of the metal silo (grain surface) were 1.9°C and 4.1°C higher than those of the wooden silo and ambient respectively. It can be concluded that wooden silo is more effective at temperature control than metal silo under the tropical conditions.
