Batch mixer for segregative, free-flowing powders and pastes

Achieve precise and gentle batch mixing for delicate products with advanced conical screw technology, ensuring high mixing accuracy and minimal power consumption for effective processing of powders, pastes, and slurries.

Mixes and Blends Powders, Pastes, and Slurries

The Nauta® Conical Screw Mixer from Hosokawa Micron stands out for its ability to achieve high mixing accuracy without compromising the integrity of delicate materials. Its convective mixing mechanism utilizes a rotating screw suspended from an orbital arm, ensuring efficient axial, radial, and tangential mixing. This equipment is ideal for applications spanning pharmaceuticals, food, and cosmetics, where precise mixing of powders, pastes, and slurries is crucial.

With a capacity ranging from 5 to 100,000 liters, it supports varying batch sizes and production scales. Capable of operating in all ATEX zones, it ensures safety and compliance for explosive environments. PLC-controlled systems allow seamless integration into automated production lines, while an energy-efficient design minimizes power consumption. Constructed from durable materials like stainless steel, it offers excellent resistance to corrosion, critical for industries handling aggressive chemicals and materials.

Certified to meet the stringent standards of GMP and FDA, the mixer supports applications in pharmaceutical and food industries. Maintenance is simplified with features such as CIP/SIP capabilities and easy access for component inspection, ensuring downtime is minimized. Customization options, such as intensifier rotors and liquid injection systems, provide additional flexibility to meet specific processing requirements.
