Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later. Drum Drying also known as Roll Drying is a continuous process that creates dry powders and flakes from a liquid feedstock. The liquid feed is sprayed onto or in between two rotating drums. The drums are heated internally with steam to increase the surface temperature. As the material is sprayed onto the drums, it sticks and dries to the surface. Drum drying can be clean and hygienic.. Drum dryers are easy to operate and maintain.. The dryers are flexible and suitable for multiple but small quantity production. The disadvantages of drum drying are the following:. Some products may not form a good film on the drum surface and are not suitable for drum drying.. Drum-drying. In the drum-drying process, puréed raw ingredients are dried over two rotating, high-capacity drums and undergo a validated kill step. Sheets of drum-dried product are milled to a finished flake or powder form. Drum-dried ingredients reconstitute immediately and Drum. Purpose. The dryer drum is where the wet material is showered through the hot drying gases to evaporate water. The drum is the most important part of a rotary dryer system. Drums that are rigid tend to last longer than those that are not. A rigid drum reduces flexing and the problems caused by cyclic loading. Symptoms. Headplate cracks
