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.}, keywords = {Drying,Spouted bed,Ammonium perchlorate,Minimum spout velocity,moisture}, url = {https://ijcce.ac.ir/article_7916.html}, eprint = {https://ijcce.ac.ir/article_7916_bc6057dd77e1c865de0891b04c426f68.pdf} }
