Abstract: 

Based on experimental data the workflow dynamics in the dryer shaft was analysed. It was confirmed that it is a stochastic dynamic system. The curves of kinetics of the process were built. Authors have assessed the uneven drying in the lower horizontal section of the dryer. It was discovered that near the outlet chamber’s wall the grain was heated more due to uneven distribution of gas. The interplay between changes of grain humidity and temperature confirmed the correlation coefficients. Fluctuations in humidity and temperature of grain lead to low quality of drying. In order to improve the quality and intensity of drying authors have offered the enhanced gas distribution system and the improved workflow regulation system.
