Purchased brand new from Diedrich, this sweetheart has had a run history of about 3 hours a day, 3 days a week. It was decommissioned about 3 months ago with owner needing to level up in batch size.

Notice that awesome LCD touch-screen flat panel suspended off the top of the attached computer system and the mechanical bean drop into the cooler. Here's why this darling is unique! Both software and mechanical automation. 

This one runs on Natural Gas with 110v power. It has been serviced, cleaned, and maintained meticulously. The pictures definitely tell the story.

This package also comes with an external chaff collector, another rarity amongst Diedrich IRs as they typically collect the chaff in the cabinet base. External cyclone allows for more efficiency in chaff collection as well ease of emptying/cleaning.

NOTE: Diedrich's Zenith II Full Automation feature and hardware is a $10,000 add-on to the base model alone! Then add on an external chaff collector, another $2,500.

The Diedrich Roaster Is Designed For Consistency And Repeatability, Ensuring A Perfect Roast Batch After Batch.

The Diedrich IR-12 can pump out up to 90 pounds per hour, depending on your roast profile. The IR series machine gives you unparalleled precision and control over your roast batches. It uses infrared burners, producing a fresh, clean coffee with all the right notes. 

Another Diedrich Roaster - it’s going to go fast!
