From the following input parameters comes a series of pathways a particle can take towards its yielded shape and size. Certain parameters like spraying gas flow, feed rate, and the solution concentration heavily influence the yielded particle size, whereas the inlet temperature plays a significant role into the shape of the particle at the end. Particle size has a great correlation with the original size of the solution droplet from the atomizer, so the greatest way to control particle size can be done by heavily saturating the solution and making the initial droplet larger or smaller. Once the initial droplet enters the drying chamber, the droplet can continue to crust formation, or no particle will be formed. From the crust formation, the temperature of the drying process and duration of the particle in the drying process can lead the particle toward a dry shell or a deformed particle. The dry shell can proceed into a solid particle or a shattered particle. The crust formation can also forgo the dry shell or deformed particle if the drying conditions are not correct and undergo an internal bubble nucleation with another series of pathways.
