modeling drying kinetics of canola in fluidized bed dryer

modeling of drying kinetics of canola was studied at 30 to 100 ?c in a lab scale fluidized bed dryer. drying rate of the crop was assessed, using many conventional moisture ratio models employed in food science. effective diffusivity coefficient (deff) and activation energy (ea) of kernel moisture were determined using fick's law of diffusion and arrhenius equation. besides, the effects of...

Improving Three Phase Modeling of Fluidized Bed Dryer

Heat transfer phenomena in batch fluidized bed dryer have been studied and analyzed using three phase model including solid phase, interstitial gas phase and bubble phase based on Rizzi model. New correlations of heat transfer coefficient to surrounding and convection heat transfer coefficient between solid and interstitial gas are being proposed. In addition, some modifications have been d...

Drying of calcium carbonate in a batch spouted bed dryer: optimization and kinetics modeling

In the present work, the drying of calcium carbonate in a batch spouted bed dryer with inert particles has been investigated experimentally. The effect of several operating parameters including air temperature (90, 100, and 110 ˚C), air velocity (Ums, 1.2 Ums, and 1.5 Ums), and dry solid mass (5, 10, 20 g) has been studied. The Taguchi method has been applied to determine the optimal parameters...

drying rough rice in a fluidized bed dryer

the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...
