Mathematical Modeling of Conductive, Convective and Irradiative Drying of Cereal Based Baby Foods

The influence of three different drying methods (conductive, convective and irradiative) on the behavior of three wet baby food mixtures during drying was studied. Conductive drying experiment was performed at drum dryer(steam pressure 6 bars ; dryer velocity 7 rpm ; material thickness 0.0002 m), convective drying experiment was conducted in tunnel dryer (drying temperatures 60 °C, 80 °C, 100 °C ; air velocities 0.5 m/s, 1.0 m/s, 1.5 m/s ; material thickness 0.005 m) and irradiative drying experiment was carried out in infrared dryer (drying temperatures 60 °C, 80 °C and 100 °C ; material thickness 0.0017 m). Drying behavior of all materials was the best described by Page’s mathematical model.
