Drum drying is a food processing method that involves drying liquid or pureed foods by spreading them thinly over the surface of a rotating drum. As the drum turns, hot air is applied to the food, evaporating the moisture and leaving behind a dry and shelf-stable product. This technique is widely used for producing items like powdered …

Freeze-drying is an extreme form of vacuum drying in which the water or other solvent is frozen and drying takes place by subliming the solid phase. Freeze-drying is extensively used in two situations: (1) when high rates of decomposition occur during normal drying; and (2) with substances that can be dried at higher temperatures, and …
