This mixer comes in a variety of sizes, for pilot to industrial scale

The Helical Dryer series HD was designed to meet the requirements of multipurpose production, as specified by a study group that included major European pharmaceutical manufacturers. The dryer incorporates an optimized mixing assembly, which features a mechanical seal (without product contact); rugged bearings; a small surface area (for reduced product hold-up); a reduced gap to the vessel wall (for enhanced mixing performance); and a 30% reduction in shaft length (so there is no bending moment). An integrated containment filter is included for processing active agents. The overall height of the HD has been reduced due to a patented bowl design. The dryer is available as a mobile unit, with a usable volume of 15–30 L, or a stationary version, with a usable volume of 100–4,000 L. Particle sizes up to 5 mm can be handled.
