Granulizing-Drying System converts moist solids into dry granules
A new granulizing-drying system, consisting of a centrifugal screener, a spheroidizer, circular fluid bed dryer, and a vibratory screener, converts non-flowing moist solids discharged from cartridge and vacuum filters, filter presses, mixers and other equipment into uniform, compact, dry, de-dusted, free-flowing granules ready for storage, shipping, packaging or secondary processing. A centrifugal screener uses rotating helical paddles to break-up lumps and drive non-flowing materials through apertures in a horizontal cylinder, producing moist pellets continuously, at high rates. The unit handles smooth, lumpy, sticky and otherwise difficult-to-handle materials, and is reportedly more productive, compact and economical than screw-type extruders. The equipment is available to industrial, 3A, FDA, USDA, BISSC and other sanitary standards, as individual components or complete, automated and integrated systems tailored to small- to large-scale granulizing applications in the chemical, food and pharmaceutical industries.
