Conventional and modified rotary dryer: Comparison of ...

Sep 01, 2009  The values of drying rate in the roto-aerated dryers were 3.1 to 4.9 times higher than in the conventional cascading rotary dryer. All these results confirm the better gas-particle contact in the roto-aerated dryers, resulting from the higher heat and mass transfer coefficients occurring in this non-conventional rotary dryer.

In this work, the performance of a conventional cascading rotary dryer has been compared with a modified configuration, known as a roto-aerated dryer. The results obtained show that for the roto-aerated dryer the residence time was 48% lower, the difference between outlet- and inlet-solids temperature was 1.7–3.3 times higher and the air ...

ROTARY DRYERS COOLERS

Direct-heat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steam-heated clean air and flue gases may be used as a heating medium. Indirect-heat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
