6kg Commercial Gas Coffee Roaster: Double-Walled Drum & Artisan Ready
For growing specialty cafes, boutique roasteries, and expanding wholesale bean suppliers, the 6kg commercial coffee roaster represents the ultimate “sweet spot.” It bridges the gap between small shop sample roasters and massive industrial machinery, offering a capacity of up to 24kg per hour while maintaining precise craft-level temperature control.
Designed for roasters who demand consistency, thermal stability, and roast curve repeatability, our 6kg gas coffee roaster combines heavy-duty industrial craftsmanship with smart digital profiling tools.
Key Engineering Features of Our 6kg Commercial Coffee Roaster
To achieve the ideal balance of convective and conductive heat transfer—preventing scorching, tipping, or underdeveloped cores—our 6kg roaster incorporates state-of-the-art thermal engineering:
1. Heavy-Duty Double-Walled Drum
Built with food-grade SUS310S heat-resistant stainless steel or specialized alloy cast iron, the double-walled drum technology creates a thermal air cushion between the inner and outer drum layers. This design shields the beans from direct conductive scorching while maximizing gentle, uniform convective heat transfer during the critical First Crack.
2. Seamless Artisan & Cropster Software Integration
Equipped with dual high-precision Omron PT100 thermocouples (measuring Bean Temperature BT and Exhaust Air Temperature ET), our 6kg roaster offers plug-and-play USB and Bluetooth data logging. Roasters can monitor, save, and replicate precise RoR (Rate of Rise) roasting curves on Artisan or Cropster software in real-time.
3. Infinite Variable Airflow & Drum Speed Control
Every bean origin—from high-altitude Ethiopian Yirgacheffe to dense Colombian washed coffees—requires tailored heat dynamics. Our unit features dual frequency inverters allowing independent, stepless adjustment of both drum rotation speed (RPM) and exhaust fan airflow.
4. Rapid Cooling Tray & Integrated Cyclone Chaff Collector
To lock in delicate origin aromas and prevent over-roasting post-drop, the high-torque cooling arm and heavy-duty suction fan reduce batch temperatures to ambient levels in under 3 minutes. An external cyclone collector efficiently removes silver skin (chaff) to maintain a clean workspace.

Frequently Asked Questions (FAQ)
Q: Can I roast smaller batch sizes (e.g., 2kg or 3kg) in a 6kg coffee roaster?
A: Yes. Thanks to our variable drum speed and adjustable gas metering valves, our 6kg machine maintains excellent thermal airflow dynamics even when roasting smaller 2kg or 3kg batches without scorching the beans.
Q: How do I connect the 6kg roaster to Artisan software on my laptop?
A: The roaster features a built-in USB/Bluetooth communication module. Simply plug the provided cable into your Mac or Windows laptop, open Artisan, select our pre-configured thermocouple driver, and start recording your Bean Temp (BT) and Rate of Rise (RoR) instantly.
Q: What is the gas pressure requirement for the 6kg gas roaster?
A: Standard units operate on 2.8–5.0 kPa for LPG or 2.0 kPa for Natural Gas. We customize burner orifices and pressure regulators to match your country’s local municipal gas standards.
