Flash Dryers & Coolers
The Heyl Patterson Flash Dryer is used for quickly drying high moisture, temperature-sensitive material with high thermal efficiency. These materials include chemicals, minerals, sludge, foodstuffs, plastics, gypsum and pre-drying hemp and wood fibers. Using the principle of selective processing, this unit ensures that every particle’s resistance time is proportional to its size and weight, resulting in a high-quality product that’s free of physical and chemical degradation.
With selective processing, your production line will deliver a high-quality commercial product with a homogeneous final moisture content, free from physical or chemical degradation.
Features & Benefits
- Provides a homogeneous final moisture content without product degradation.
- Small footprint flash design efficiently processes high capacities in less space than conventional dryers.
- Quickly and efficiently dries powders and granules with high-moisture content.
- Speed of drying makes flash dryers ideal for use as a pre-dryer to expand production capacity on existing process lines.
- Handles feed rates ranging from 50 to 1600 pounds per hour.
- Alumina
- Flour
- Fluorspar
- Municipal Solid Waste (MSW)
- Polyethylene
- Sodium Bicarbonate
Flash Drying Designs
From conventional flash drying technology to our Rotacurrent and Venturijet design, materials are quickly and efficiently dried. We also offer flash coolers to quickly bring down the temperature of your products.
We also offer Rotary Dryers & Coolers and Fluid Bed Dryers & Coolers for our customers’ other specifications.
Our industrial flash dryers can utilize higher gas temperatures than other drying technologies since the material retention time is very short.
Built to your unique specifications, or designed by our engineers to exceed your specific application requirements, each Flash Dryer can be pilot tested at our Innovation Center & Test Lab before the final design is implemented.

Flash Dryers & Coolers FAQs
What is a flash dryer & cooler?
A flash dryer and cooler is a pneumatic processing system that rapidly dries or cools fine particulate materials by suspending them in a high-velocity stream of hot or cool gas. Because the particles are dispersed in the gas stream, heat and mass transfer occur very quickly, allowing moisture removal or cooling in a matter of seconds.
What materials are typically processed in flash dryers & coolers?
Flash dryers & coolers are commonly used for fine powders, filter cakes, pastes, and slurries. Typical applications include starches, minerals, chemicals, pigments, and food ingredients.
Why choose flash drying instead of other drying methods?
Flash drying is ideal for materials that require rapid moisture removal and short residence times. The process can handle heat-sensitive materials while maintaining consistent product properties.
How does a flash dryer handle sticky or wet materials?
Flash dryers often include mechanical disintegration devices or feed systems that break apart wet agglomerates before drying. This allows the material to disperse in the air stream and dry efficiently.
What are the benefits of flash drying & cooling systems?
Flash dryers offer compact system design, rapid drying times, continuous processing capability, and efficient moisture removal. They are commonly used when production requires high throughput and consistent powder characteristics.
