After the atomization, the solution was washed with scCO2 in order to extract the remaining organic solvents.
Air-jet atomization of solution into droplets followed by controlled drying is increasingly being used for producing nanoparticles for drug delivery applications.
The air spray gun give you the best atomization result, with medium volume air pressure.
Polyvinylpyrrolidone (PVP folic acid (FA) Microspheres [174] BSA (bovine serum albumin) Nanoparticles (60 nm ± 10 nm) [174] SAA (supercritical-assisted atomization) The organic solution and supercritical carbon dioxide (SC-CO2) are mixed; they form an expanded liquid in a saturator.
A TSI constant output atomizer (model 3076) was used for atomization of aqueous solutions.
This work describes the design and manufacture of a seeder based on ultrasonic atomization of aqueous solutions or other fluids of similar viscosity, capable of operating in a continuous way with high atomization rates.
Nanoparticles were prepared using air-jet atomization of precursor solutions of stearic acid in organic solvents (acetone, chloroform, methanol and ethanol), in a pulse heat aerosol reactor, at a process temperature of 50 °C.
Combined with the ultrasonic atomization technology, the desiccant solution can be atomized into tiny droplets with diameter about 50 μm, which may greatly facilitate the dehumidification process.
The process variables studied were inlet air temperature, inlet air flow, spray rate of the binder solution, and atomization air pressure.
