Aseptic spray drying versus lyophilisation

An equivalent quantity can be manufactured using spray drying within a shorter period — because of high-volume capacity — and with less energy consumption. Product Quality Benefits Spray drying also contributes to a higher standard of manufactured product. Lyophilisation subjects materials to freezing temperatures, which can lead to damage.
