Abstract
This article discusses the issues of designing a dryer structure for the primary drying process of grain products based on systematic analysis. The study comprehensively evaluated the relationship between technological and aerodynamic parameters of the drying process, heat and mass transfer indicators, air flow directions, and hydrodynamic resistance in the grain layer. During the design process, rational values for the optimal geometric shape of the dryer, drying agent temperature, moisture removal intensity, and energy consumption were determined using systematic analysis methods. The theoretical and practical results obtained will serve to increase the efficiency of the grain drying process, effectively use thermal energy, and create new generation designs of dryers.
