The Witte Company Vibrating Fluid Bed Dryers and Vibrating Fluid Bed Coolers, Vibrating Dewaterers and Vibrating Screeners

The Witte Company designs and manufactures vibrating fluid bed dryers and coolers, dewaterers, screeners and related process equipment. Privately-owned and operated since its founding in 1938, Witte has earned a stellar reputation for engineering expertise, craftsmanship and personal service.

Witte has developed innovations in machine design, while formulating what has become its signature vertical air-flow engineering and establishing a track record for operational dependability, safety and longevity. Dow, DuPont, Bayer, Merck, Pfizer, Roche, Nestles etc and other global leaders in the chemical, pharmaceutical, plastics, food and related process industries rely on Witte and have for decades.

The company not only guarantees the workmanship of its equipment, but also guarantees the equipment’s performance in your processing line.

CUSTOM DESIGN VIBRATING FLUID BED DRYERS AND COOLERS FOR POWDERS TO PELLETS

Witte custom designs vibrating fluid bed dryers and coolers to meet demanding specifications for moisture content, shape, purity, crystallinity and other parameters. Drying the product while gradually moving it forward toward the discharge, Witte Dryers gently handle virtually any product including:

  • Soaps and detergents
  • Herbicides and pesticides
  • Cleaners and disinfectants
  • Strippers
  • Electro-chemicals
  • Ion exchange resins
  • Chlorine and bromine
  • Vitamins and analgesics
  • Enzymes and proteins
  • Cosmetic powders
  • Plastic Pellets

WITTE VIBRATING FLUID BED DRYER AIRFLOW TECHNOLOGY INNOVATIONS

Witte’s signature vertical airflow engineering is based on the understanding that drying or cooling air flowing vertically through the product dries more efficiently than air that “short circuits” at an angle. In fact, air flowing at even slightly more or less than 90 degrees creates dead spaces where drying is weak and hot spots where drying is too strong. This causes charring, clogging and layering which all lead to stoppages for cleaning and high reject rates.

But in a Witte system, air flows vertically, perpendicular to the fluid bed deck, and at a constant velocity. This ensures uniform heat history throughout the entire length of the system.

The result is a thin layer of product in intimate contact with the air flowing delicately and evenly from feed to discharge, with the first product in as the first product out. To achieve this precise airflow control, Witte devised an advanced Air Distribution System and pioneering Wedge-Wire Decks and Autoweirs that work together for maximum drying and energy efficiency.

WITTE VIBRATING FLUID BED DRYERS, VIBRATING FLUID BED COOLERS, VIBRATING FLUID BED DEDUSTER VIBRATING SCREENERS FOR PELLET TECHNOLOGY

Witte offers a range of custom and off-the-shelf systems and equipment proven to increase productivity and upgrade end product uniformity in pellet operations.

WITTE SERIES MODEL 200 VIBRATING SCREENERS FOR PELLETS

The 200 Series Pellet Classifier, responsible for separating nearly half of all on-spec plastic material produced in the USA, earned widespread acceptance for its reliable performance, designed-in ease of cleaning, negligible maintenance and quiet operation.

WITTE SERIES MODEL 400 VIBRATING FLUID BED DRYER / DEDUSTER / DEWATERER AND VIBRATING SCREENERS FOR PELLETS

The choice of Chevron, DuPont, Dow, BASF and other global resin manufacturers and compounders, Witte’s range of plastic processing equipment is highlighted by its breakthrough Witte 400, the first integrated, multi-step system combining air classification, cooling, surface drying, chip removal and oversize removal in a single unit.

WITTE SERIES MODEL 700 VIBRATING SCREENERS DOUBLE SCREEN THE “OVERS” FOR HIGHER EFFICIENCY

The company’s 700 Series Pellet Classifier boasts two perforated decks for high product uniformity including an ‘oversize’ deck, which actually screens the product twice and significantly reduces the amount of ‘short longs’ in the final product.

WITTE’S VIBRATING FLUID BED DRYERS AND SCREENERS ARE DESIGNED FOR SAFETY, CLEANABILITY AND EASE OF MAINTENANCE

Whether designing a classifier, dryer, dewaterer or other machinery, Witte engineers ensure each machine complies with EPA/EU regulations, provides unmatched safety features and invites easy access to the entire system for cleaning.
