VIBRO-BED™ Dryers, Coolers and Moisturizers


Complete circular vibratory fluid bed systems skid mounted ready to process

Greater performance in less space at lower cost than ever before possible

Kason fluid bed dryers, coolers, and moisturizers employ an innovative circular processing unit which is inherently stronger, lighter, and less costly to build and finish to sanitary standards than rectangular units having equivalent surface area.

Because the circular fluid bed processor is also more compact, complete fluid bed systems can be pre-engineered and pre-configured on caster-mounted frames, ready for installation and start up.

Moreover, Kason circular fluid bed processors maintain an unprecedented level of operating efficiency across a wide range of model sizes from 18 to 84 inches (460-2540 mm) in diameter for laboratory and pilot plant testing as well as batch or high-volume in-line drying, cooling, or moisturizing of bulk foods, pharmaceuticals, and chemicals.

Principle of Operation

Fluid bed processors dry, moisturize, heat, or cool bulk solid material by causing it to vibrate on a screen or perforated surface within a rising column of heated, chilled, or moisturized air.

Continuous air flow and vibration separate and fluidize individual particles, maximizing the surface area of material and, accordingly, the rate at which drying, moisturizing, heating, or cooling can occur.

To prevent the uppermost layers of fluid bed particles from being pulled into the exhaust stream, the fluid bed exhaust plenum tapers outward, effectively reducing the air velocity by 50 percent.

The vibratory motion of the processor also serves to convey the material along a defined pathway for uniform processing on a "first in/first out" basis, and to evacuate the fluid bed at the end of each cycle.

To fit your material application and integrate with existing plant equipment, Kason offers a comprehensive range of equipment available as components, sub-systems, or complete systems.
