The entire drying process of a rotary flash dryer

2026,03,16
In flash drying, wet material enters the grinding and drying section of the dryer body via a customized feed system. A grinding rotor disperses the wet material into very fine particles, which are fluidized in the grinding chamber by temperature-controlled hot gas from an air heater.
 
The hot air (or inert gas) can be heated to 650°C, and its size is reduced at the bottom of the Flash Dryer as the wet product is dispersed. The system maintains negative pressure via an exhaust fan, significantly increasing the surface area of ​​the product, causing water (or other solvents) to evaporate instantaneously.

The dried and fine particles are conveyed with the airflow to the top of the dryer, where a separator classifies the particles by size. The particles then pass through the classifier at a set cut point and are conveyed with the exhaust gas to a dust-air separation system, such as a cyclone separator or cyclone Dust Collector.
 
The rotary flash dryer maintains a fluidized bed of product within the drying chamber to ensure low-level adhesion of the wet material to the chamber walls. In addition, process parameters such as classifier speed and outlet temperature can be used to control the moisture content and particle size of the final product.
