Summary The aim of this work was to study the simultaneous heat and mass transfer between air and soybean seeds in concurrent moving bed dryers. The stationary behaviour of the process was described by the mass and energy equations applied to both fluid and particulate phases, assuming uniform velocity of the seeds and flat velocity profile of the air. The results of the fluid‐dynamic study confirmed that the velocity of the seeds and air inlet profiles were essentially uniform. The experimental data and simulated values of the temperature of the fluid and temperature and moisture of the seeds were in good agreement.
