Double-Deck, Circular Vibratory Fluid Bed Processors are inherently rigid, allowing materials of construction to be down-gauged and vibratory motors to be downsized. Associated components are also eliminated, such as multiple air inlets and outlets and their associated ducting? the circular unit requiring only one of each. The result is a unit of significantly lighter weight and higher operating efficiency, with lower capital cost and a smaller footprint. Reductions in material, weld seams, and associated labor also decrease fabrication cost, particularly when units are finished to FDA, USDA, BISSC or 3-A standards. Four models of the patent pending, double-deck fluid bed processor range in diameter from 48 inches to 84 inches (1220mm to 2135mm), satisfying medium- to high-volume production requirements. All are available configured for continuous drying, cooling or moisturizing applications.
