Nutsche filter dryers
Drying
Applications
Nutsche filter dryers are widely used in:
- The pharmaceutical industry (APIs, antibiotics, peptides)
- The chemical and fine chemicals industry (catalysts, pigments, polymers)
- Biotechnology (fermentation products, proteins)
- The food industry (additives, extracts, flavorings)
- High-potency and toxic substances (closed-loop processing)
Product overview
Nutsche filter dryer – batch filtration and drying system
The Nutsche filter dryer is a closed, vertical batch system in which multiple process steps take place without product transfer.|
Principle of operation:
- The suspension is introduced into the vessel
- Liquid is separated via a filter medium (filtration)
- Solid material (filter cake) can be washed
- Heating and vacuum ensure drying of the product
- Mechanical agitation ensures homogeneity and efficient drying
This combination results in a controlled and reproducible process with minimal handling.
Key features
