One technique to improve physical properties is the foam centrifugal spray drying method. This method was initially used to improve thermal efficiency and later to adjust product performance. Practice has proved that foam spray-dried products have large particle size, porous, porous, heavy, rough surface, and good soybean. Some require spherical particles with uniform particle size. In general, various forms of particles can be achieved by changing the atomization method. Before choosing the centrifugal spray dryer, the commodity manufacturer, with the assistance of the equipment manufacturer, conducted parameter optimization experiments to determine a better parameter combination to ensure the drying effect of the sprayed drug.
