12kg Diedrich IR-12 Used Coffee Roaster

2020 Fully Automated Roaster With External Chaff Collector and Catalytic Oxidizer

Opportunities like this don’t come around often. If you’ve been searching for the perfect balance of shop-sized performance, reliability, and compliance, this package has your name on it. This fully automated 2020 Diedrich IR-12 with external chaff collector PLUS a Diedrich Catalytic Oxidizer is a matched set that’s built to deliver consistency in every batch and keep the air clean while doing it.

Why This Makes Sense for Your Roastery

The IR-12 is a workhorse for roasteries ready to level up. With its automated infrared burner system, it makes roasting predictable and repeatable — just set the profile, let it run, and watch as the system handles the cooler, agitator, and drum door for you. That means more efficiency, fewer mistakes, and roasts you can stand behind.

Need output? You’ll get about 70 lbs. per hour from four medium roasts in the 12–15 minute range — all while cooling and roasting simultaneously. And with the catalytic oxidizer destroying up to 98% of pollutants and odor at 640–750°F, you can keep your neighbors happy and meet compliance standards without stress.

The Story On This One

This isn’t a roaster that’s been run into the ground. Its one and only owner bought it new in 2020 and has only used it lightly — just a couple of days a week, 2–3 hours per day. The only reason it’s for sale? They’re upsizing to keep up with growth.

The oxidizer comes with all connecting ducting between the roaster and afterburner, making it a complete turnkey system. Lightly used, well cared for, and ready to go.

If you’ve been waiting for the right IR-12 opportunity, this is it.
