Coffee Roaster Afterburners for Sale

Coffee Roaster Afterburners for Smoke and Odor Control

A coffee roaster afterburner reburns the smoke, odor, and volatile compounds coming off your drum, so your exhaust stays within local air quality limits and the neighbors stop calling. This collection covers new and used coffee roaster afterburners from Diedrich, Probat, and independent afterburner builders, sized for a single shop roaster or a full production line. Each listing notes condition, BTU rating, and the roaster size it's built for, so you can match a unit to your exhaust volume before you buy. Already have a roaster picked out?

Why Buy Your Coffee Roaster Afterburner Through CoffeeTec

An afterburner stops being optional once your roaster's exhaust draws attention from a neighbor or the local air district. Buyers here get new units and inspected used ones from names like Diedrich, Probat, Clean Stream, and VortX, plus non-combustion filter options for shops that need an alternative to an open flame. Every listing lists condition, BTU or SCFM rating, and the roaster it's built for. Have a used afterburner or filtration system to sell instead? List it with CoffeeTec and reach buyers already searching this category.

Thermal vs. Catalytic Afterburners

Thermal afterburners use straight heat, typically in the 1,250°F to 1,400°F range, to break down smoke and odor compounds. Catalytic afterburners run a coated catalyst bed instead, so the same reaction happens at a lower temperature, often with lower gas use over time. Either style burns extra fuel to do its job, and industry estimates put an afterburner's gas draw at two to three times what the roaster itself uses. The right pick comes down to your exhaust volume, ongoing fuel cost, and how strict your local air permit is.

Matching an Afterburner to Your Roaster

Afterburners are rated by SCFM and BTU output, and both numbers need to line up with your roaster's exhaust. A unit built for a 12kg drum won't keep pace behind a 60kg roaster, and an oversized unit on a small roaster just burns gas for no reason. Check the roaster size listed on each afterburner and compare it against your own drum capacity first. Not sure what you need? Our team can help you cross-reference specs before you order.

Afterburner Alternatives

A combustion afterburner isn't the only route to cleaner exhaust. Wet scrubber and electrostatic filter systems pull smoke and chaff from the airstream without an open flame, which suits roasters with tight space or limited gas access. Browse our Indumax filter systems collection for a non-combustion option worth comparing against a standard afterburner. Running a full post-roast line? Pairing an afterburner with a destoner rounds out your setup between the drum and the bagger.

Shopping by Roaster Brand

Several afterburners here are built to pair with a specific roaster line. Running a Diedrich roaster? Look for a DCO model sized to your IR series. Probat owners should check units built around the TO-2 and similar Probat-compatible burners in our Probat collection. Matching brand and model first narrows the field fast, even when the afterburner itself isn't a Probat or Diedrich part.
