摘要
A novel Rotating Jet Annular Spouted Bed (RJASB) dryer was developed for drying of particulates in the falling rate period. This gas-particle contactor consists of one rotating spouting air jet in the annular region of a cylindrical vessel. Effects of the spouting jet rotational speed, bed height, and nozzle diameter as well as particle size, shape and density on the minimum spouting velocity as well as peak and steady spouting pressure drops were determined experimentally and correlated empirically.
