Coffee roaster RoastMaster™

drumhot air

Overview
Drum roasters in the RoastMaster™ Series cover small-scale to industrial throughput (up to 1 t/h). They support traditional and multistep roasting profiles and are engineered for homogeneous heat transfer to achieve consistent roast results.

Key benefits

• Adjustable roasting parameters: Control hot-air temperature and airflow to shape flavor development and influence physical bean characteristics.
• Energy-efficient homogeneous roasting: Available as open or hot-air recirculation systems; roasting chamber and drum design optimize heat transfer for uniform results and reduced energy use.
• Profile repeatability: Touch-screen control with recipe functions enables precise control of roast degree, time and temperature evolution for reproducible profiles.

Highlight features

• Digital ecosystem — Playone: Web-based machine control providing real-time data, trend monitoring and recipe adjustment; RoastMaster™ 20 control accessible from PC/tablet and integrable with Bühler Insights or third-party software.
• Modular design: Options to build an integrated bean‑to‑cup line, adaptable to plant layout (examples: pneumatic feeder, pneumatic destoner discharge, afterburner).
• Range of models: RoastMaster™ 20 (≈70 kg/h), 60 (≈240 kg/h), 120 (≈500 kg/h), 240 (≈1000 kg/h) — series capable up to 1 t/h depending on configuration.
• Engineering & consultancy: Manufacturer services for planning, engineering, automation, project management, installation, start‑up and maintenance.

Application possibilities

• Coffee roasting for artisan and industrial production, suitable for mono-origin and blend profiles across a range of throughputs.

Services and training
Technical services, commissioning support and operator training are available to ensure safe, efficient operation and to transfer recipe and process knowledge.

Customer stories
