In drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam/ hot air inside, at a desired pressure raising the temperature of the cylinder wall. The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods.
The dried product is removed from the drum with the help of a scrapper/blade. Vacuum drum drying is used when the materials are highly sensitive to heat. In that system, the drum and its accessories are enclosed in a vacuum chamber. Drum drying is extensively used in the production of instant mashed potatoes, precooked cereals, soup mixtures and low-grade milk powder.
