The Witte Company has developed a range of dryers and coolers that eliminate the need for a dedicated, gluten-free drying system.

The US food equipment manufacturer has designed a cleanable vibrating fluid bed that allows complete access for cleaning and inspection.

This enables food manufacturers to process gluten-free flours on the same processing lines used for glutenous products, without the risk of cross-contamination.

Going gluten-free

Gluten-free flours can be made from bananas, corn, potatoes, almonds and rice; while glutenous products include wheat, rye, barley and oats.

Processors have easy access to the entire interior of the machine for complete cleaning and the thorough inspections required to verify the removal of non-soluble solids in Readily Clean in Place (RCIP) sanitation systems.

The Witte fluid bed dryers and coolers allow a single operator to quickly access the interior of the machine without any tools.

The company's signature C-clamps are opened to release the exhaust cover from the conveying surface. An electric hoist then raises the cover to expose the dryer deck and holds it in place while cleaning and visual inspection are performed.

CA complete cleaning takes only 10-20 minutes, making product changeovers a seamless process, while processors can be assured that contaminant removal may be verified, assured and documented.

Family owned and managed

The Witte Company, founded in 1938, designs and manufactures vibrating fluid bed dryers, coolers, pellet classifiers, dewaters and other vibratory process equipment at its headquarters in Washington, NJ.

Last year, Tyson Witte took over as president, representing the fourth generation of leadership for the family-owned manufacturer. He succeeded Richard Witte, now chairman, who guided the company for 30 years.

The company has supplied equipment to some of the world’s biggest food processors, including Kellogg’s, Nabisco and General Mills.
