Granulizing-Drying System

This granulizing-drying system consists of a centrifugal screener, a spheroidizer, a circulating fluid-bed dryer, and a vibratory screener. Non-flowing moist solids that have been discharged from cartridge and vacuum filters, filter presses, mixers or other equipment are converted into uniform, compact, dry, de-dusted, free-flowing granules that can be stored, shipped, packaged or put through secondary processing. Its Centri-Sifter centrifugal screener uses rotating helical paddles to break up lumps and drive non-flowing materials through apertures in a horizontal cylinder, thereby continuously producing moist pellets at high rates. Binder powder may be applied before the materials enter the unit or with internal spray nozzles. The fluid-bed dryer vibrates and dries particles on a perforated screen within a rising column of heated air on a first-in/first-out basis. Dried particles are discharged into a vibratory screener that uses an upper screening deck to gently remove oversized particles and a lower deck that removes undersized dust particles for re-processing. This screener operates on a batch or continuous basis. The system’s equipment meets industrial, 3A, FDA, USDA, BISSC and other sanitary standards.
