Abstract
The thermal properties such as specific heat, thermal conductivity, thermal diffusivity and volumetric heat transfer coefficient for three different oil producing crops (sunflower variety Giza 102, soybean variety Giza 111 and canola variety Serow 55) were  determined at five different levels of seeds moisture content and temperature. The results show that, the specific heat was found to be both seeds moisture content and temperature dependent. Its value increased linearly with the increasing of both seeds moisture content and temperature for all studied crops. Also, the seeds moisture content had higher effect on seeds specific heat than that of seeds temperature. Thermal conductivity and thermal diffusivity were increased with the increase of seeds moisture content while, thermal diffusivity decreased linearly with the increasing of seeds temperature for all studied crops. Also, the volumetric heat transfer coefficient was increased linearly as the air flow rate and air temperature increased.
Mathematical relationships were also developed for the different studied crops to relate the change in seeds moisture content, temperature and mass air flow rate with the obtained values of all thermal properties.
