Flash Dryer for Catalysts: Gentle Drying of Heat-Sensitive Catalyst Materials
How a spin flash dryer dries catalyst materials fast and gently, with cooling-water protection at the chamber base to prevent scorching of heat-sensitive products.
Many catalysts and catalyst supports are dried from a wet paste or filter cake and are heat-sensitive — too much heat scorches or discolours them and can harm catalytic activity. A spin flash dryer dries them in seconds, and a cooling-water device at the hot chamber base protects the material, making it well suited to heat-sensitive catalyst drying.
The drying challenge
- Heat-sensitive — excess heat scorches or discolours the catalyst and can reduce activity.
- Wet paste or filter cake that is too thick to pump.
- Controlled moisture and fineness for consistent catalytic performance.
Why a spin flash dryer fits
- Fast, gentle drying in seconds protects heat-sensitive catalyst materials.
- Cooling-water protection at the hot chamber base prevents scorching and discolouration.
- Even drying and controlled fineness via dual-air-duct tangential intake and the top classifier.
- Handles the wet paste or cake directly with the bottom agitator.
Sizing guide
Size against your water-evaporation rate:
| Throughput tier | Suggested model | Chamber Ø | Water evaporation |
|---|---|---|---|
| Small line | XSG-4 to XSG-6 | 400–600 mm | 58–163 kg/h |
| Mid-scale | XSG-8 to XSG-10 | 800–1,000 mm | 238–430 kg/h |
| Large production | XSG-12 to XSG-16 | 1,200–1,600 mm | 515–1,203 kg/h |
