Dryer/Classifier

The food-grade 418-D dryer/classifier is a multi-step system that integrates sanitary drying, cooling, classifying, and fines collection in a single, compact unit. Applying the engineering of the Witte 400 series plastic pelletizing system in a sanitary design, the 418-D dryer/classifier features a vibrating fluid bed dryer, a wire mesh fines collection screen, steam-heated air supply, and cyclone exhaust with blower with continuously welded and polished T-304 stainless steel in product contact areas. Ideal for processing starches, nuts, snack chips, and other food and dairy products in low volumes or in pilot scale lab settings, this dryer/classifier meets USDA, FDA, and 3-A standards and regulations for contact with food and dairy products. The system also includes an exhaust air silencer to support compliance with OSHA specifications for permissible sound exposure levels and high-efficiency particulate air (HEPA) filters on both the air supply inlet and the exhaust to promote hygienic drying while also permitting the safe return of the filtered process air into the plant or outdoor environment.
