In order to realize sterilization of the aseptic spray dryer, the following improvements are adopted:
After being heated, the external cold air will be filtered by the hot air HEPA filter, so that the air quality can meet the GMP medicine production standards.
Mix the slurry and filtered water and stir it. Then mix the filtered air and slurry and realize atomization via two-fluid atomization nozzle to get better atomization effect and to meet the requirements of aseptic spraying.
To prevent powder sticking on the inner wall of the drying tower, the drying tower is equipped with air sweeper which can realize easy cleaning of the powder sticking on the inner wall.
