Preparation of spray dried submicron particles: Part B – Particle recovery by electrostatic precipitation

In conclusion, an ESP customized for collecting particles in the range of 0.1–1 µm was designed, built and tested, and collection efficiencies higher than 99% were achieved for submicron particle size distributions. For a robust process continuous cleaning of the charging stage is necessary.Graphical abstract
