Effect of drum drying temperature on drying kinetic and ...

2017-9-1 · The drum clearance was set at 2 mm for all processing. The drying temperatures (100, 110 and 120 °C) were set by the steam pressure feed and the drying times were fixed by the rotation speed of the drums. For each drying temperature five batches (100 g each) of pomegranate peel were processed at different times at atmospheric pressure.

Drum-Drying - an overview | ScienceDirect Topics

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.

DT-6: Lesson 27. DRUM OR ROLLER DRYING

Often, two drums are set up side by side at a very small distance apart. The water evaporates within a few seconds, which is possible due to the high drying temperature (>100°C). On a drum drier, the product enters as a liquid and leaves as a solid. The product is removed from the exterior of the drum by a "doctor" blade.
