The National Technical University of Athens (NTUA) offers its customers the Spray Freeze Dryer for the development of nanopowders with different functionalities due to the presence of active compounds (e.g. antimicrobial activity). The spray freeze dried particles are incorporated into polymers using a twin screw extruder to develop functional pellets for different applications.

Specification of the nanopowders and pellets:

Throughput: up to 4 kg/day of nanopowders and up to 10 kg/h of pellets

Diameter of the powder particles: 200-600 nm

Development of nanopowders and pellets with different functionalities and extended shelf life of active ingredients

Controlled release of active ingredients: depending on the final application.
