چکیده

ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. the solid particles obtained in this process of drying were semi-porous and known as the group d of geldart classification. the variations of moisture content with resident time, the effects of bed height on the pressure drop, and the influence of moisture content on drying rate were investigated. in this project, the air flow rate and the moisture diffusivity were determined. a model to determine the minimum spout velocity and also a model based on the fick’s law were obtained which predicted the experimental data very well.

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...
