Infrasound Drying
Harnessing low-frequency sound for smarter, more efficient drying
A modular system
A modular system designed for flexibility and scalability. Components can be configured, expanded, or adapted as your needs evolve. This ensures long-term performance without unnecessary complexity.
“The only thing we need to know is your requirements.”

Drying to your needs
With our EU-backed project underway, we’re sharing results from InfraDryer #3: a full-scale infrasonic dryer for grain and biomass powered by a solar-driven heat pump. Building on InfraDryer #2, it can cut energy use by about 40% versus conventional dryers. Designed for year-round use, it makes fossil-free drying more cost-effective for farms and supports 2030 climate goals. Four test campaigns in 2025–2026 confirmed performance, showing it can replace oil-based dryers and significantly reduce CO₂ emissions.
The Drying Process
The principle of drying wheat in a hot air dryer
The air flow has two functions:
- Mass transfer of water from the surface to the air
- Transport of water
Mass transfer requires high air velocity. For water transport, a low air speed is desirable.
The principle of drying wheat in an infrasound dryer
The mass transport of water from the surface to the air is enhanced by an intense infrasound with a high particle velocity.
