Nutsche filter-dryer for solid-liquid separation
Ensure precise moisture control and efficient solid-liquid separation for high-purity compounds with this versatile solution, seamlessly integrating filtration, washing, and drying processes within your production line.

Processes Filtration, Washing, and Drying
The Nutsche Filter-Dryer from AUSTAR is engineered for precise solid-liquid separation, crucial in pharmaceutical, chemical, and food industries. It operates by integrating multiple processes, such as filtration, washing, and drying, ensuring efficient handling of active pharmaceutical ingredients, cytotoxic compounds, and specialty chemicals. The system can manage batch, manual, or continuous operations, adapting to varying production requirements and accommodating solids, liquids, slurries, and cakes.
Its innovative design includes a heated, fully welded filter plate which accelerates drying by directly transferring heat from the bottom through all contact surfaces. The air knife system facilitates product discharge, while the lateral discharge valve minimizes contamination risks. With a containment level of OEB5, it safely handles high-potency active pharmaceutical ingredients.
The equipment supports diverse filtering materials, providing flexibility with filter cloths or multi-layer sintered metal mesh. Integrated PAT technology allows online monitoring of solvent residues, enhancing process control. These features, combined with its robust design, make it a reliable choice for maintaining purity and efficiency in demanding production environments.
