Abstract
A process and apparatus utilizing the process of the present invention are provided to produce a fast dissolving, thermally sensitive granular product. The process employs a fluidized spray dryer having a fluidized bed of granular particles into which recycled off-sized product is fed after being agglomerated to adjust particle size. The spray dryer optionally can employ a second nozzle positioned above the fluidized bed. The process can be employed in the production of calcium hypochlorite water sanitizing chemical wherein the chlorine is supplied from a hypochlorous acid reactor and lime hypochlorinator.
