What Is a Shop Coffee Roaster?
A shop roaster is a compact, commercial-grade machine typically used in coffee shops, micro-roasteries, and training labs sitting between the Sample PRO 100 and our commercial roasters in our full roasting machines range. Designed for 1kg to 6kg batch sizes, it bridges the gap between sample testing and full production offering the flexibility and precision needed for small-batch excellence without the footprint or overhead of a commercial-scale machine.

Why Choose a Shop Roaster from Coffee Pro Direct?
At Coffee Pro Direct, we design shop roasters specifically for roasters, educators, and entrepreneurs. We craft every feature to optimize performance while ensuring sustainability, ease of use, and long-term durability.
Precision Control
All three shop roasters the CM1, CM3, and CM6 use traditional drum roasting technology with a 12–18 minute roast cycle that allows full flavor development and even heat extraction. Adjustable heat and airflow settings give roasters complete control over every stage of the roast curve.
The system includes Artisan software as standard for detailed data logging, roast profiling, and batch replication. Users can also upgrade to Cropster compatibility across the range.
Advanced Burner Technology
The CM3 and CM6 feature Metal Fiber pre-mix burners that combine air and gas before combustion delivering even, stable heat distribution throughout the drum and up to a 50% reduction in CO, CO₂, NOx, and aldehydes compared to traditional atmospheric burners meeting environmental benchmarks referenced by the International Coffee Organization for responsible coffee processing. The CM1 uses an atmospheric burner at 31.76 BTU efficient and reliable for its batch range. All models support precise, responsive heat adjustment mid-roast so you’re always guiding the profile, never chasing it.
Eco-Friendly and Compliant
Coffee Pro Direct’s shop roasters are designed with environmental responsibility built in. The pre-mix burner technology on the CM3 and CM6 delivers near-zero emissions when properly installed, and all models comply with international environmental standards. They’re safe for indoor café and lab module use when paired with appropriate ventilation a practical choice for urban roasting environments where air quality compliance matters. Pair with the Sample PRO 100 for a complete roast development and quality control setup.
Built to Last
These are not starter machines that you’ll outgrow in a year. The CM1 weighs in at 125 kg, the CM3 at 250 kg, and the CM6 at 450 kg heavy-duty, heat-stable, food-safe construction that holds up under daily commercial production pressure.
