Abstract

This study is concerned with the development of temperature profile inside a maize cob. There was no significant difference in the temperature distribution through the central region during heating or cooling. A faster temperature response was noticed in the germ part. The resistance to heat flow seems to be considerable in a region between the germ and the root of the kernels. Airflow has no significant effect on the temperature distribution, at least within the velocity range of 1.14 m/s to 2.33 m/s. Thermal diffusivities were calculated by graphical method and found to be in close agreement with the results for other cereals.
