EXPERIMENTAL STUDY ON THE MAIN PARAMETERS DETERMINATION FOR SESAME SEEDS ON THE BATCH PULSED FLUIDIZED BED DRYER

Abstract

The paper presents the results of experimental research to determine the technological parameters of sesame drying process in the batch pulsed fluidized bed dryer. The experiments were carried out according to the 2-level orthogonal experimental plan, combined with multiple response optimization according to Response Surface method (RSM) to determine the optimal parameters (gas temperature, gas velocity, pulsed speed) in the sesame drying process. As the result, the optimal parameters were determined such as: gas temperature was Z1opt = 63,13C, gas velocity was Z2opt = 1,21 m/s, pulsed speed was Z3opt = 12 RPM. Corresponding to these optimal parameters, the objective functions reached the minimum value, including the final moisture content Y1min = 6,26%, the specific electrical energy Y2min = 408 Wh/kg vapor
and the specific heat value consumption Y3min = 4989 kJ/kg vapor.
