What makes a Ribbon Blender Sanitary?
Ribbon blenders can be designed for sanitary food, pet food, cosmetic, API (active pharmaceutical ingredients) and any blending application that required good cleanability including colorants, catalysts, detergents, air freshener, potpourri, and even dry industrial cleaning chemicals.

All welds must be ground smooth, flush and pit free, shaft seals must be air or liquid purge and easily disassembled for cleaning.
