Abstract

One of the effective DRYING mechanisms is FLUIDIZED BED dryer where particles are fluidized by hot air. Mixing and heat transfer are very rapid, therefore the DRYING time is short. In order to study the mechanism of DRYING under different conditions a two-fluid model is imposed. The model uses one-dimensional conservation of mass, heat and momentum equations for each phase of gas and solids. Numerical method is carried by finite-volume scheme. The verification of the theoretical results was done by the use of an experimental setup. The results indicate a good qualitative agreement. By eliminating the convective terms in a solid phase and drags model; PACKED BED condition is obtained. The result verified with the performed PACKED BED experimental data. Futher, with the proposed model, the performance and comparison of fluidzed and PACKED BED dryer can be shown.
