Abstract
The paper presents the effect of corn kernel moisture and various temperatures and drying air speed on the change of kernel volume. In the process of drying corn kernel volume decreases. According to the data obtained the decrease is 24.8% (if the kernel containing 32.7% of moisture is dried to 13.2% at the temperature of 85°C). The investigation was carried out on the hybrid BC 492 at drying air temperature of 85°C and 100°C and air speed of 0.8; 1.1 and 1.3 m/s. The moisture level of the corn kernel dried was between 18 - 33%. The kernel containing 24.61% of water, dried at air temperature of 85°C shrank by 15.7%, while the kernel containing 24.77% of water, dried at air temperature of 100°C shrank by 6.8%. Various drying air speeds did not have a significant effect on the change of kernel volume. The data on the outside dimension changes of the kernel (length, width and thickness) in the course of various drying conditions are also given.
