How Do Indirect Heat Rotary Dryers Work?

Jun 24, 2016· How the Indirect Heat Dryer Works. Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace. This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber. As the material progresses down the length of the unit, it is subjected to different temperatures in

Process Advantages of Indirect Heat Dryers

Process Advantages • Product is isolated from the burner flue gases. • Material is heated through radiation and conduction. • Processing material is contained in an atmosphere that can be controlled through the introduction of nitrogen or other gas to facilitate or retard a reaction inside the rotating drum.

Indirectly heated tube drum dryers BÜTTNER Energy & Drying

In doing so, the water contained in a product is evaporated into the dryer air, which is preheated by heat exchangers. At the end of the dryer drum, the dried product is separated in a drop box and discharged through an air-tight rotary valve. Warm and moist dryer air is extracted and dedusted in cyclones or bag filters.

Indirect Rotary Dryers Vulcan® Drying Systems

Vulcan® Indirect Rotary Dryers are built to rigorous safety and performance standards because they are 100% designed, manufactured and tested in the USA. Vulcan® Indirect Rotary Dryers rely on the heat transferred through the drum’s shell to dry the material via conduction and radiation to reduce the material’s moisture content.

Indirect Drying vs. Direct Drying FEECO International Inc.

Indirect dryers rely on the heat emanating from the drum’s shell to dry the material via conduction and radiation. Subsequently, indirect dryers would not benefit from the addition of lifting flights, since there is no process gas moving through the drum. Furthermore, because the furnace exhaust is kept separate from the process gas, indirect
