Factory-Direct Commercial Coffee Roasters
for U.S. Roasteries
Yoshan has manufactured drum coffee roasters since 1990 — from 1 oz sample machines to 660 lb industrial plants. Siemens PLC automation, cast-iron drums and Probat/Giesen-grade engineering, shipped to U.S. ports at factory-direct pricing.
Find Your Roaster
From first cupping sample to full production — one drum philosophy across the range, so your profiles scale as your roastery grows.
1 oz – 1.1 lb
Sample Roasters
Cupping-lab and product-development roasters with full data logging. Build a profile on a sample machine, then scale it to production on a matching Yoshan drum.
2 – 7 lb
Shop Roasters
1–3 kg drum roasters for cafés roasting in-house and nano-roasteries. Manual craft control or full PLC automation — same drum geometry, so your profiles scale up cleanly.
13 – 66 lb
Commercial Roasters
6–30 kg production roasters with Siemens PLC automation and cast-iron drums. Two design lines: Giesen-style (YS) and Probat-style (SD Pro). Built to run shift after shift.
132 – 660 lb
Industrial Roasters
60–300 kg fully-automatic roasting plants — Yoshan is the only factory in China building a true 300 kg (660 lb) drum roaster. Complete lines engineered to your floor plan.
