The influence of gas-pulsed flow when supplied in the perpendicular direction to the refined standard (RS) sugar layer has been studied in this article. Some hydrodynamic parameters of the RS sugar in the gas-pulsed fluidized bed have also been determined. The research results have been applied in the design of the RS sugar dryer using the modern pulsed fluidized bed drying method. The bed porosity in the static particle layer (e₀) was 0.44 while the bed porosity in the minimum fluidized bed (e_mg) was 0.484 and the minimum fluidized bed velocity (U_mg) was 0.65 m/s. The bed porosity in the homogeneous fluidization bed (e_hg) was 0.67, and the homogeneous fluidization velocity (U_hg) of 1.63 m/s has been calculated. The critical velocity (U_cg) of 2.7 m/s and the bed porosity (e_cg) of 0.8 in the circulating particle bed were determined. The pressure drop through the layer of RS sugar with a thickness of 300 mm was 3808 N/m².
