The biggest hurdle to installing a roaster in the U.S. usually isn’t the machine — it’s the smoke permit. Here’s the short version.
Why roasters need abatement
Roasting releases smoke, VOCs and chaff particulate. Local air-quality districts (like California’s AQMDs) set limits, and many require control equipment above a roast-capacity threshold.
Thermal afterburner
Burns off smoke and odor at 200–1,000°C. Required in strict VOC/odor districts. Higher running cost because it consumes gas, but it’s the gold standard for approval.
Electrostatic precipitator (ESP)
Captures 95%+ of particulate electrostatically, runs on electricity, and is quieter and cheaper to operate — a strong choice where the limit is particulate and odor is less of an issue.
Also on the checklist
NFPA 86 gas-train safety, a mechanical/ventilation permit, and adequate gas supply. We configure the roaster and abatement so your local engineer can complete the review.
