Improving the efficiency of corn drying in a conveyor belt dryer

Abstract

The paper deals with the theoretical background of drying corn kernels in the moving bed. The authors present a system of the drying medium (drying air) uniform distribution in the dryer. They proposed a system that can improve the performance of the conveyor dryer. A rationale for the essential geometry features of the system is provided. The system implies air supply through two rows of multidirectional nozzles. The proposed layout increases the flow velocity at the nozzle outlet by 35–45%. The study determined the optimum values of the four-stage process for drying corn kernels in a conveyor dryer: for the drying medium, the average temperature was tdm =35 … 50 °C, the velocity at leaving the moving bed was Vdm = 1…1.5 m/s.
