Abstract: A series of experiments for wheat, bean and pea seeds on the pulsofluidized bed dryer were carried out. Based on the results of this investigation the aerodynamics and drying kinetics of pulsoflu-idized bed drying were analyzed. The relationship between the drying rate and drying air temperature, superficial air velocity, static bed height, pulsation frequency and perforation rate of screen were developed. Also, the relationship of pressure drop with static bed height was obtained.
