Fluid Bed Dryer

Witte Vibrating Fluid Bed Dryers

Witte Vibrating Fluid Bed Dryers offer a series of engineering advances that yield superior drying performance. Showcasing the company’s signature vertical air flow engineering, Witte dryers feature a porous conveying surface set within an enclosed vibrating vessel. This proprietary technology directs heat transfer air or gas to pass up vertically through the product, creating the high degree of fluidization that promotes maximum air contact with the product surface for superior drying performance.

Drying while the product gradually moves forward toward the discharge, Witte vibrating fluid bed dryers gently handle virtually any product from the most delicate snack chip to the heaviest rock product while assuring particle integrity and ultimately meeting your tightest drying specifications.

Witte dryer designs offer:

  • Air distribution cage uses static pressure buildup rather than baffles, permitting uniform control of air velocity over the entire dryer conveying surface
  • Wedge wire conveying surface features triangular profile wires with a thin, tapered slot, providing seven times more open area than the typical drilled deck and delivering superior heat exchange
  • Every six foot increment of dryer length features independent controls for air temperature and velocity, including a cooling zone, if desired
  • Controlled exhaust air assures uniform vertical air flows and eliminates the high, horizontal air currents near the bed that disturb the material flow
  • Automatic weirs provide unprecedented control of bed depth and/or retention time without product degradation
  • Entire dryer is accessed and cleaned by one person by releasing the clamps, engaging the cover lift hooks and raising the cover with the convenient hand winch or with automatic control
  • Sanitary stainless steel designs with continuously welded seams available to meet USDA, FDA and 3-A standards and regulations
  • Material which enters first, leaves first

Witte vibrating fluid bed dryers are guaranteed to work as specified.
