The Witte Company, Inc products

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.

Witte Vibrating Fluid Bed Coolers offer a series of engineering advances that yield superior cooling performance. Showcasing the company’s signature vertical air flow engineering, Witte fluid bed coolers feature a porous conveying surface set within an enclosed vibrating vessel. This proprietary technology directs ambient 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 cooling speed and performance.

Witte plastic pellet classifiers separate “fines” and “overs” from on-spec plastic material with such precision that nearly 50% of the plastic resin in the United States is classified on Witte equipment. Resin manufacturers and compounders especially appreciate the designed-in ease of cleaning, negligible maintenance and quiet operation.

The Witte 700 Series Classifier is recommended for those plastic pellet applications where particular emphasis is placed on the uniformity of the final, pelletized product.

The innovative Witte 400 combines the 200 or 700 series vibrating plastic pellet classifier with the vibrating fluid bed dryer/cooler to deliver drying, cooling and classifying in one, self-contained unit. This plastics processing system is capable of meeting the following objectives:

Witte vibrating dewaterers quickly drain large quantities of liquids from slurries of granular solids. With a gentle, vibrating action, the wet material is moved uphill and over a series of dams squeezing out the liquid. Witte dewaterers provide an inexpensive means of separating large quantities of liquids from solids.

Witte Vibrating Screeners gently and efficiently screen dry, granular, free-flowing and non-free flowing products while protecting product integrity.

Witte Vibrating Conveyors gently and safely feed, move and screen dry, granular, free-flowing, and non-free flowing products efficiently and cost-effectively while protecting product integrity.

The Witte clamp is one of the clever design elements that make Witte process equipment easy to access and clean. The C-20 clamp and the new, larger C-30 permanently mount onto equipment to deliver up to 1,000 or up to 1,700 pounds of clamping force, respectively, yet easily retract with one hand. Removing and re-connecting covers, doors, panels and hoods from machinery and equipment are fast and easy. There is no need to struggle with steel bolts, carbon steel clamps, toggle clamps and other fastening systems. If you need both a tight seal during operation and easy operator access for quick cleaning and maintenance, this clamp is for you.

Witte vibrating packers gently compact powders, pellets, and other dry materials in a container to increase net contents per container, permit the use of smaller containers for the same net contents and/or to strengthen and add rigidity to a container for safe stacking and handling.
