What is a Drum Dryer? wiseGEEK

A drum dryer is a rotating cylinder that uses steam or hot air to heat feedstock and reduce the moisture content during a manufacturing process. The configuration may include one or more drums. A drum dryer may use atmospheric pressure or function under a vacuum. Drum dryers have many applications in the food industry because they are very efficient for drying pastes or gelatinous materials

With the Royal GMF-Gouda drum dryer running costs can be significantly lower than with other dryers. Its high thermal efficiency translates to steam consumption of approx. 1.4 kg for each kilogram of water evaporat-ed. Useful energy can even be recovered as it exits the system. Drum drying is environmental friendly as well; there is hardly any dust emission thus avoiding complicated filter

Drum drying

31/10/2007 Drum drying is a method used for drying out liquids from raw materials with a drying drum. In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product. This product is milled to a finished flake or powder form. Modern drum drying techniques results in dried ingredients which

The design of flights in rotary dryers ScienceDirect

26/11/2001 Rotary dryers for particulate solids commonly use flights along the length of the shell to lift solids and make them rain across the dryer section. These flights are critical to dryer performance.
