Flash drying is an inexpensive solution to drying powders and granular materials, and is designed for high moisture materials with a constant-rate drying zone.
Carrier’s industrial flash dryer systems can use higher gas temperatures, versus other dryer types, because the material retention time is very short. Flash drying is accomplished with a large quantity of gas and active heat exchange, which simultaneously transports the processes materials.
Industrial flash dryers are well suited for:
Drying materials with high moisture contents in the constant-rate drying zone. High temperature drying gas is blown into the duct, where material is continuously fed, dried, and transported. The processed material is separated from the exhaust gas and collected by a cyclone or bag filter in the flash dryer system.
Features and benefits of Carrier flash dryers:
- Capable of processing high capacities in a relatively small amount of space.
- Often used as a pre-dryer to expand production capacity on existing lines.
- High thermal flash drying efficiency.
- Crushing of lumps is possible with addition of a Cage Mill to the flash dryer system.*
*For dispersion of material, de-agglomeration equipment, such as a Cage Mill or scatter is used. Carrier offers to quote these items as an option.
- If size reduction is not desired, a mechanical slinger is available for the flash dryer system to disperse sticky materials.
- Pneumatic conveying while flash drying eliminates additional equipment.
- High process gas temperatures possible for reduced size and cost.
- Industrial flash dryer systems designed for easy installation.
- Furnished through a license agreement with NARA Machinery Company, Ltd., Japan — a world-class leader in fluidized bed technology.

Flash Dryers FAQs
What is a flash dryer?
A flash dryer rapidly removes moisture from fine particles by suspending them in a stream of hot gas, enabling drying in seconds.
What materials are suitable for flash drying?
Flash dryers are commonly used for powders, fine chemicals, minerals, starches, and other materials with small particle sizes.
What are the advantages of flash drying?
Flash drying offers fast moisture removal, compact equipment footprint, and efficient processing of fine or lightweight materials.
How does particle size affect flash dryer performance?
Smaller particles dry faster because they have more surface area exposed to the heated airflow.
Are flash dryers suitable for heat-sensitive materials?
Yes. Because the drying process occurs quickly, flash dryers can often process materials that require short exposure to heat.
