Indirect Drying vs. Direct Drying - FEECO …
Conversely, indirect dryers do not utilize direct contact with process gas to dry the material. In fact, this is the precise advantage of an indirect rotary dryer for two reasons: It avoids the issue of fine materials becoming entrained in a process gas, which can be a problem when processing fine materials in a direct dryer.
Rotary Dryer: Operating principle, Classifications, …
Direct-heated rotary dryer. Indirect- Direct rotary dryer. Indirect rotary dryer. Special type. A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class.
Direct and Indirect Heat Rotary Dryers - Schenck …
The rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length. With heat transfer indirect and through the cylinder wall, the gas velocities within an indirect dryer are low as compared to a direct heat dryer, and correspondingly, the off-gas system is smaller and more economical.
How does Direct Heat Rotary Dryers Work?
The Louisville Rotary Direct Heat Dryer is a continuous type dryer which operates primarily through convective heat transfer. Wet material, which is to be dried, is fed into one end of a rotating drum and travels to the other end where it discharges as dry product into a transfer conveyor.
What are the benefits of Indirect Heat Rotary Dryers?
These types of materials are easily aspirated from, or degraded in, a conventional direct fired, or direct heat dryer, therefore leaving little time to be brought up to temperature. The Louisville Dryer Indirect Heat Dryer provides the perfect tool to accomplish each of these tasks as effectively as possible.
Rotary Dryer - Industrial Rotary Dryers …
The co-current direct-heat rotary dryer is the most common, wet material is in contact with the hot gas stream as its highest temperature, which causes rapid evaporation of surface moisture. As it progresses through the dryer, heat energy is lost to the material it is drying and it leaves the dryer at a comparatively low temperature.
