Used Coffee Roasters

Pre-Owned Coffee Roasting Machines, From Sample to Production

Shop used coffee roasters for sale from Probat, Diedrich, US Roaster Corp, Giesen, Mill City Roasters and dozens of other brands. The range runs from gram-scale sample roasters for cupping labs to production drums and full roasting lines. Every listing shows batch size, year built, condition grade and location. That lets you compare a used coffee roaster machine on facts, not a stock photo.

Most machines here come from roasteries that upgraded or changed their setup, so proven models turn up at every size. Have a roaster to sell instead? List it on our sell-equipment page and reach buyers already shopping this collection.

Why Buy a Used Coffee Roaster From CoffeeTec

CoffeeTec has served the coffee industry since 1972. The idea behind this collection is simple: you should know what you're buying before it ships.

So listings carry the details roasters actually ask about. You'll see batch capacity, fuel type and power needs. You'll see last-used and last-serviced dates where the seller has them. And you'll see what's included, such as a cyclone, loader, destoner or afterburner. Many listings also note when crating is included, and our team helps arrange freight once you're ready to buy.

Types of Used Coffee Roasters for Sale

• Used commercial coffee roasters: Drum roasters in the 5 to 30 kg range for wholesale accounts and growing retail brands.
• Sample and lab roasters: Gram-scale units for cupping, green evaluation and profile work, including multi-barrel models that roast samples side by side.
• Fluid-bed and air roasters: Hot-air machines with fast heat transfer and a bright cup. Many are all-electric, which suits indoor shops without a gas line.
• Refurbished and rebuilt roasters: Machines with rebuilt burners, drums or controls. Check each listing for the rebuild date and who did the work.
• Production roasters and mini plants: Drums of 20 kg and up, sometimes listed with loaders, destoners and afterburners as one line.

Fuel narrows the field fast. Of the roasters listed on CoffeeTec from October 2024 to October 2026, about half ran on natural gas, a quarter on propane and one in five was all-electric.
