Blitz-Trockner und -Kühler
Der Heyl Patterson Flash Dryer wird zum schnellen Trocknen von feuchten, temperaturempfindlichen Materialien mit hoher thermischer Effizienz eingesetzt. Zu diesen Materialien gehören Chemikalien, Mineralien, Schlamm, Lebensmittel, Kunststoffe, Gips sowie vorgetrocknete Hanf- und Holzfasern. Nach dem Prinzip der selektiven Verarbeitung sorgt dieses Gerät dafür, dass die Verweildauer jedes Partikels proportional zu seiner Größe und seinem Gewicht ist, was zu einem hochwertigen Produkt ohne physikalische und chemische Qualitätsverluste führt.
Durch selektive Verarbeitung liefert Ihre Produktionslinie ein hochwertiges Handelsprodukt mit einem homogenen Endfeuchtigkeitsgehalt, das frei von physikalischen oder chemischen Qualitätsverlusten ist.

Flash-Trocknungsdesigns
Von der herkömmlichen Flash-Trocknungstechnologie bis hin zu unseren Rotacurrent- und Venturijet-Konstruktionen werden Materialien schnell und effizient getrocknet. Wir bieten auch Flash-Kühler an, um die Temperatur Ihrer Produkte schnell zu senken.
Wir bieten auch Rotationstrockner und -kühler sowie Fließbetttrockner und -kühler für andere Spezifikationen unserer Kunden an.
Unsere industriellen Flash-Trockner können höhere Gastemperaturen als andere Trocknungstechnologien nutzen, da die Verweildauer des Materials sehr kurz ist.
Jeder Flash Dryer wird nach Ihren individuellen Vorgaben gebaut oder von unseren Ingenieuren so konzipiert, dass er Ihre spezifischen Anwendungsanforderungen übertrifft. Vor der Umsetzung des endgültigen Designs kann jeder Flash Dryer in unserem Innovationszentrum und Testlabor getestet werden.

What is a Flash Dryer & Cooler?
The Heyl Patterson Flash Dryer and Cooler is a pneumatic thermal processing unit designed to rapidly dry high-moisture materials by dispersing them in a high-velocity stream of hot gas. Its purpose is to deliver fast, continuous moisture removal with minimal residence time, making it particularly effective for temperature-sensitive materials and high-capacity operations where speed and product quality cannot be compromised.
So funktioniert es
The Heyl Patterson Flash Dryer and Cooler uses pneumatic conveying and direct gas-to-particle contact to achieve rapid heat and mass transfer. It is engineered around four integrated principles that work together to give processors precise, high-throughput drying performance.
Selective Processing
Material is introduced into a high-velocity hot-gas stream, where particles are immediately dispersed and conveyed upward through the drying column. The key principle is selective processing: larger, heavier, and wetter particles resist the gas velocity and remain in the active drying zone longer, while smaller, lighter, and drier particles are carried out of the column more quickly. This means every particle’s residence time is proportional to the drying it actually needs, producing a homogeneous final moisture content without over-drying fines or under-drying coarse particles.
High-Temperature Short-Exposure Drying
Because residence time in the flash dryer is measured in seconds rather than minutes, inlet gas temperatures can be significantly higher than those used in conventional dryers without damaging the product. The material surface temperature remains close to the wet-bulb temperature of the gas throughout the active drying phase, protecting heat-sensitive materials from thermal degradation while still achieving rapid moisture removal.
Feed Preparation and Dispersion
Wet, sticky, or pasty feed materials are conditioned before entering the drying column using mechanical disintegration devices, custom feeders, or back-mixing systems that blend incoming wet feed with already-dried product. This dispersion step is critical to performance: it ensures the material enters the gas stream as individual particles rather than agglomerates, maximizing surface area exposure and enabling efficient drying from the first moment of contact.
Design Flexibility
Heyl Patterson offers conventional flash drying technology alongside proprietary Rotacurrent and Venturijet designs, each suited to different material characteristics and throughput requirements. Flash coolers are also available to rapidly reduce product temperature after drying or other thermal processing steps. The main body can be clamped or bolted for interior access, and custom feeders, air slides, and bag filters can be integrated to match the specific demands of the application.
Key Benefit
This design is well-suited for quickly drying powders, granules, filter cakes, and high-moisture materials, including chemicals, minerals, plastics, gypsum, flour, and municipal solid waste, where minimizing thermal exposure, maintaining product integrity, and achieving consistent final moisture content across variable feed conditions are essential to production quality.
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.
