View full detailsAbout Drum Coffee Roasters
Drum roasters are the standard for roasteries that want deep, developed flavor and steady batch control. Each machine tumbles green coffee inside a rotating, heated drum, giving you slower, more even heat transfer than an air or fluid bed system. You'll find drum roasters here from Probat, Diedrich, US Roaster Corp, and other trusted names, spanning small shop sizes up through full production capacity. Every listing includes real specs: batch size, fuel type, condition, and service history, so you can compare machines the way you'd compare any other major equipment purchase.
Weighing a drum roaster against an air roaster? Our drum vs air roaster guide breaks down the difference in flavor, speed, and batch size. Have a roaster to sell instead of buy? Visit our sell equipment page and put your current machine to work funding your next upgrade.
Why Buy a Used Drum Roaster from CoffeeTec
Drum roasting has been the industry default for decades because it rewards patience. The slower, indirect heat lets sugars develop and body build up, which is why so many wholesale and cafe roasters stick with drum machines batch after batch. Every drum roaster listed here is condition graded and comes with the details you need before you buy: capacity, fuel type, hours or last-used date, and service history. You can browse our full lineup of used coffee roasters if you want to compare drum machines against sample and fluid bed styles side by side.
Drum Roasters by Batch Size
Batch size is usually the first thing to narrow down. A small shop roasting for a single cafe has very different needs than a wholesale operation running multiple accounts.
| Batch Size | Best For |
|---|---|
| 1 to 4 kg | Single cafe roasting, retail bags, starting a small roastery |
| 5 to 18 kg | Wholesale accounts, growing production, multiple retail locations |
| 20 kg and up | Established production roasteries and high-volume wholesale supply |
Most growing roasteries land in the middle tier. Browse our 5 to 18 kilo drum roasters if that sounds like where you are.
Popular Drum Roaster Brands
Two names come up again and again when roasters talk about drum machines. Our Diedrich drum roasters use infrared burners for even heat and consistent, repeatable batches, and this 2.5 kg Diedrich IR-2.5 is a good example of what a low-hour, well-serviced machine looks like on our site. Our Probat drum roasters are known for durable drum construction and consistent heat retention, a strong pick for roasteries planning to run a machine hard for years. You'll also find US Roaster Corp, Mill City, San Franciscan, and other established drum brands throughout our inventory.
Drum vs Air: A Quick Comparison
Drum roasters develop richer, fuller-bodied coffee through slower, indirect heat, and they generally handle larger batch sizes than air roasters, which use fast-moving hot air for a brighter, cleaner cup. Neither style is universally better. It comes down to the flavor profile you're roasting for and the batch sizes your business needs.
FAQs
What is a drum roaster and how does it work?
+A drum roaster tumbles green coffee inside a rotating, heated drum. Heat transfers to the beans through the drum wall and through direct contact, roasting them slowly and evenly. This slower process is what gives drum-roasted coffee its typical body and depth.
Drum roaster vs air roaster: which is better?
+It depends on the cup you want and the batch size you need. Drum roasters tend to produce richer, more complex flavor and handle bigger batches, which is why they're common in wholesale and cafe roasting. Air roasters roast faster and produce a brighter, cleaner cup, but usually in smaller batches.
How much does a used drum roaster cost?
+Pricing depends heavily on batch size, brand, and condition. Small shop-sized drum roasters typically start in the low thousands, mid-size 5 to 18 kg machines run into the tens of thousands, and large production roasters climb well beyond that. Every listing on this page shows the actual asking price and condition grade.
What size drum roaster do I need for my business?
+Match batch size to your actual weekly volume rather than where you hope to be in a few years. A single cafe usually does well with a 1 to 4 kg machine, growing wholesale accounts tend to need 5 to 18 kg, and established production roasteries look at 20 kg and up.
Can I finance a used drum roaster through CoffeeTec?
+Yes, CoffeeTec offers monthly financing options on used coffee roasting equipment, including drum roasters, so you can secure the machine you need while managing cash flow.
