The Witte 400 vibrating fluid bed dryer-cooler-classifier reduces the temperature of plastic pellets from 100°C to 50°C at up to 5000 lb/hr using ambient air. Integrating drying, cooling, dedusting, and classifying into a single, compact unit, the Witte 400 removes residual moisture that may condense during packaging, separates minus 20 mesh “fines” to pass the “hand test”, removes minus 10 mesh chips, and then removes “oversize” material, yielding consistently on-spec pellets for clog-free bag filling and packaging.
The Witte 400 is ideal for processing nylons, polyesters, polyurethanes, polystyrene, polyethylene, polypropylene, polyvinyl chloride, and other commodity and engineering resins. The self-contained plastic pellet system opens easily to expose the interior for cleaning and inspection, and is available with a motorized, hands-free safety hoist, a choice of steam, gas, or electric process air heating systems, and a variety of custom options.
