Diedrich roasters for sale on this page cover the full IR and CR lineup, from 1kg lab units to large production machines. CoffeeTec inspects every used Diedrich before it goes live. You get a clear read on condition, usage history, and included accessories before you buy.
Diedrich built its reputation on infrared burner technology and hand-fabricated construction, made entirely in the USA. That combination shows up in roast clarity and mechanical durability, from a single café roaster to a full wholesale production line. If you roast in the 5 to 18 kg range, check the medium batch roasters collection for other brands at the same output level.
Diedrich Roaster Types at a Glance
Diedrich builds infrared drum roasters across several size classes, each built for a specific production scale. Here's how the lineup breaks down.
| Model | Batch Size | Best For |
|---|---|---|
| IR-1 / IR-2.5 | 1 to 2.5 kg | Profile development, training labs, startup cafés (see small batch roasters) |
| IR-3 / DR-3 | 3 kg | Entry commercial roasting, independent specialty operations |
| IR-5 / IR-7 | 5 to 7 kg | Steady weekly production for wholesale accounts |
| IR-12 | 12 kg | Established roasteries managing multiple accounts |
| CR-35, IR-24, and up | 24 kg and above | Contract roasters and regional suppliers running continuous volume (see large batch roasters) |
Diedrich also builds the DR-3E, its main electric model for cafés with limited gas access or tighter ventilation rules.
Why Buyers Choose Diedrich
Infrared Burner Precision
Heat applied through infrared radiation lets beans develop from the inside out instead of the surface first. That lowers scorching risk and supports cleaner flavor clarity than roasters that rely on direct flame contact alone.
Built to Last, Parts Included
Every Diedrich ships hand-fabricated in the USA, and the brand has kept parts available across model generations. Afterburners, drum components, and control panels typically stay serviceable well past the original purchase date. Diedrich's IR series also works with Cropster and Artisan for roast data logging, so you can review a machine's roast history alongside its condition report before you commit.
Resale Value That Holds

FAQs
What does the IR stand for in Diedrich model names?
+IR stands for infrared, Diedrich's signature burner technology. Infrared heat transfers energy through radiation instead of direct flame contact. That supports even bean development and cleaner cup profiles across the roast range.
How much does a used Diedrich roaster cost?
+Pricing depends on batch size, model year, and condition. A compact IR-1 or IR-2.5 generally costs less than a 12 kg IR-12 or a large CR-series machine. Our buyer's guide to used coffee roasters lays out typical price ranges by size category, and each listing above shows its own price and condition.
What is the difference between a Diedrich IR-5 and an IR-12?
+The IR-5 handles 5 to 7 kg batches and suits growing wholesale accounts. The IR-12 steps up to 12 kg batches for established roasteries managing multiple accounts at once. Both share the same infrared burner and independent airflow control found across the Diedrich lineup.
Does Diedrich make an electric roaster?
+Yes. The DR-3E is Diedrich's main electric model, built for urban cafés or facilities with limited gas access. Most of the wider Diedrich lineup, from the IR-1 through large production units, runs on gas.
What should I check before buying a used Diedrich roaster?
+Ask about service history, hours of use, and which accessories come with it, such as the afterburner and chaff collector. CoffeeTec inspects each listing before it goes live. Our condition guidelines page explains what terms like "excellent" and "good" mean on a listing.
What is the typical lifespan of a used Diedrich coffee roaster?
+With regular maintenance, Diedrich machines routinely stay in active service for 20 or more years. Hand-fabricated construction and steady parts supply mean a well-maintained used unit can keep performing at a commercial level long after its original purchase.
