Electric Hot Air Afterburner Solution for Coffee Cocoa Roasting
Using Leisters Hotwind System Vulcan System – Swiss Heating Technology for a Greener Roast
Clean Roasting with Electric Afterburners – Effective, Sustainable & Regulation-Ready
Roasting coffee, cocoa, or other agricultural products naturally releases smoke, odors, and volatile organic compounds (VOCs). As environmental regulations tighten, modern roasters are switching to electric hot air afterburners – a clean, safe, and highly efficient method to:
- Burn off smoke, oils, and VOCs
- Eliminate odor emissions
- Meet environmental compliance standards
- Replace traditional fossil-fuel burners
Why Emission Control Is a Must in Coffee Roasting
In Vietnam and many international markets, coffee roasting is increasingly subject to air quality and environmental protection regulations.
Vietnam’s environmental requirements (as per QCVN 19:2009/BTNMT):
- Total suspended particles (TSP): ≤ 400 mg/Nm³
- CO emissions: ≤ 1000 mg/Nm³
- SO₂ & NOx limits: must meet local thresholds
- Odor nuisance must be controlled for urban production zones
International standards (EU/US):
- VOC limits: often < 50–100 mg/Nm³
- Odor threshold: measurable control required
- Required for export-oriented facilities to meet GMP & ESG criteria
→ Installing a reliable afterburner system is not only an environmental responsibility but a legal and competitive requirement for sustainable production and export.
Advanced Electric Afterburner Technology – Efficient, Sustainable, and Environmentally Friendly
During the roasting process of coffee, cocoa, and various agricultural products, smoke, odors, and volatile organic compounds (VOCs) are naturally released. Electric hot air afterburners are a modern and eco-friendly solution to:
Completely eliminate smoke and odors
Neutralize VOCs and organic residues
Ensure compliance with environmental regulations
Operate safely without fossil fuels
