  • Drum-Drying - an overview ScienceDirect Topics

    A pilot electric drum-dryer was tested for drying wet slurry containing 30% solids of Scenedesmus algae at 120°C for about 10 s [81]. The rate of energy consumption under such operation was 52 kWh. Conversely, replacement of the electrically heated drum dryer by a steam-heated dryer could lower the processing cost by 6.8 times. Operating at a steam pressure of 8 atm, water loss of up to 50 kg ...
