Description
Ultrasonic cleaning uses high‑frequency acoustic waves to generate cavitation bubbles that implode, creating microjets that mechanically dislodge contaminants from surfaces.
Technical
The process relies on acoustic cavitation, where rapid bubble collapse produces localized high temperatures and pressures, generating hydroxyl radicals and microjets that remove biofilms and particulate matter. In culinary settings, operating at 20–40 kHz, 1–3 W cm⁻² for 5–15 minutes in a 20–60 °C bath achieves rapid, chemical‑free sanitization.
