Our Vertical Mixer Dryer – Ribocone consists of a vertical cone-shaped vessel with a special combination of top-placed vortex breakers and a helical ribbon agitator with minimal clearance to the side walls. The internal dead-free design avoids cross-contamination and eases the cleaning process. The vertical ribbon mixer dryer is lifted along the heated side wall and falls through the center of the chamber, resulting in a uniform temperature and humidity.
