Agitated nutsche filter dryer for solid-liquid separation

Achieve high-purity solid-liquid separation with optimized throughput and contamination prevention, addressing critical process challenges in achieving homogeneous products across varied production lines.

Performs Filtration, Separation, and Vacuum Drying

The Nutsche Filter Dryer (FNB-S) by Bachiller combines agitated pressure filtration and vacuum drying to meet demanding solid-liquid separation needs, especially in pharmaceuticals and fine chemicals. Its hermetic design prevents contamination, making it ideal for hazardous materials. Operating under pressures up to 3 bar(g) and temperatures up to 200°C, this equipment supports reactions, drying, and cake washing in batch modes. Its versatile filtering surface ranges from 0.07m² to 15m², with capacities from 19L up to 15,000L, catering to various production scales. Constructed from durable materials like Hastelloy, and compliant with cGMP and EHEDG standards, it ensures purity while minimizing waste. The FNB-S integrates smoothly into production lines with automation options and energy-efficient features, supported by CIP/SIP systems for streamlined cleaning. Optional mirror polishing and electro-polishing enhance its corrosion resistance, while hardware and software control options offer precise process management.

Benefits

  • Eliminates contamination risk with hermetic processing.
  • Saves time and labor costs through semi-automatic and automatic batch operations.
  • Ensures high product purity suitable for sterile applications.
  • Reduces energy usage through optimized vacuum drying processes.
  • Complies with GMP and EHEDG standards for pharmaceutical and fine chemical industries.
