Filtration and drying is a critical part of the API manufacturing process. Conical blender dryers are a complex, all in one system that accomplishes the task for drying the crystallized slurry. Rheo offers containment and material handling options for the loading and pack-off of the dry powder. The Fixed Mount Slewing Drum Inverter can lift, invert, and position the drum of material into the blender dryer. The Mobile Ventilation Sleeve is a simple, yet effective containment option that provides local extraction during the pack out process.
