1 oz – 1.1 lb
Sample & R&D 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.

For green buyers, QC labs and roasteries that need to evaluate lots before committing. Electric heating means no gas line — plug into a standard 240V outlet and roast.
