In spray drying, a liquid feed (as a solution or a suspension) is sprayed into a hot gas stream with the intention of isolating products in a solid form as well-defined powder. Through spraying, the liquid evolves as small droplets with precisely defined volume(s). These droplets are then transported with the gas flow along a drying chamber (referred to as ‘flight time’). During the flight time, the solvent evaporates from the droplets until only residual solids remain. T
