How can rotary valves prevent contamination when conveying food ingredients?

In terms of options and accessories for the food processing industry, food-grade coatings and materials such as stainless-steel, Lectrofluor, and XTR-Coat are the best at preventing contamination. Rotors with U-shaped vanes reduce material packing and make cleaning easier. The valve itself must be properly welded and finished to ensure the surfaces are smooth and durable, which means there will be no cracks or crevasses for bacteria to build up.
