Sanitary Ribbon Blenders: What Makes It Sanitary And What Are The Use Cases?

January 30, 2025


Sanitary ribbon blenders are designed for industries where hygiene and cleanability are critical, including food processing, pet food, cosmetics, active pharmaceutical ingredients (API), and applications like colorants, catalysts, detergents, air fresheners, potpourri, and even dry industrial cleaning chemicals.

To meet sanitary requirements, the ribbon blender’s product contact parts are made of stainless steel with a surface finish of at least #4 polish, 180 grit, or 32Ra. All welds must be smooth, flush, and free of pits, while shaft seals should feature air or liquid purge systems, allowing for easy disassembly and thorough cleaning. The top cover is designed to fully open, eliminating any hidden or hard-to-reach areas, ensuring direct visibility for operators during cleaning.

The discharge valve should be simple, accessible, and visible from both the top and underneath, allowing for easy disassembly when needed. Externally, the blender features stainless steel surfaces polished to at least a 120 grit or finished with a virgin glass bead blast. A direct-drive system—without belts or chains—eliminates the need for complex guards that could trap contaminants.

For optimal hygiene and accessibility, the ribbon blender should be installed at least 3 feet from any wall, providing easy access for regular inspection and maintenance.
