Simulation For Design of Commercial Concurrentflow Grain Dryers

ABSTRACT A simulation model for concurrentflow drying based on diffusion within spherical products was de-veloped. Multistage concurrentflow dryers with inter-mediate tempering and a counterflow cooler were sim-ulated. The model matched previously published single-stage results and experimental results sufficiently well for use in the design of multistage concurrentflow dryers. Design considerations are drawn from the experimental and simulation experiences.
