ABSTRACT
The article describes aspects of drying corn in a classic pulsed fluid bed dryer (PFB) and a spouted pulsed fluid bed dryer (SPFB). Experimental results demonstrate a modest difference in drying kinetics and time between the PFB and SPFB for the same amount of seeds. Analysis of data showed that drying kinetics is dependent on the temperature, bed height and the frequency of the disc in the gas distributor. Drying kinetics was modeled mathematically using classic models and the best correlation was obtained for the modified Page's model. A modification of the Page's model was proposed which led to a 97.6% and 99.4% correlation between experimental and calculated values of moisture content for PFB and SPFB, respectively.
