Acoustic Cleaning with Sonic Horn to Prevent Buildup & Improve Efficiency
Spray drying is a critical process in industries like food, pharmaceuticals, chemicals and dairy, transforming liquids into powders. However, powder buildup inside spray dryer, cyclones and bag filters leads to clogging, contamination and reduced efficiency. Traditional cleaning methods—such as manual scraping or compressed air—are disruptive, labor-intensive and often ineffective.
Sonic horns are compressed-air driven acoustic cleaning solution to maintain optimal spray drying performance. By using high-energy, low-frequency sound waves, sonic horns dislodge buildup without stopping production or damaging equipment.
How Sonic Horns Work in Spray Drying
Sonic horns (acoustic cleaners) use low-frequency (100~125Hz), high-energy sound waves to:
- Break particle adhesion – Vibrations disrupt electrostatic & moisture bonds.
- Fluidize deposits – Stuck powder loosens and falls by gravity.
- Prevent future buildup – Continuous or timed operation keeps surfaces clean.
Benefits with Acoustic Cleaning
- Food grade stainless steel.
- Explosion-proof configuration.
- Online clean during operation, reduced downtime.
- Non-contact cleaning, no mechanical cleaning to equipment.
- Hygienic – Reduces contamination risks.
- 360° cleaning by omnidirectional sound waves.
Industries That Benefit from Acoustic Cleaning
- Food & Dairy (milk powder, whey, coffee, starch)
- Pharmaceuticals (spray-dried APIs, excipients)
- Chemicals (detergents, catalysts, ceramics)
- Biotech (enzymes, probiotics)
