The WA-6 coffee roaster is a professional gas-driven commercial roasting equipment tailored for specialty coffee shops, medium-small roasteries and coffee laboratories. Adopting premium industrial materials and intelligent PLC touchscreen control system, this machine supports continuous non-stop roasting with single batch capacity ranging from 1kg to 6.5kg, stable output and consistent roasting performance to match daily commercial production demands.
1. Heavy-Duty Carbon Alloy Roasting Drum
- The core roasting drum is manufactured with 8mm thick carbon steel alloy, recognized as the ideal material for balanced heat transfer during coffee roasting.
- Thick reinforced welded support brackets inside the drum enhance structural stability and greatly extend service lifespan.
- Specially engineered mixing blades deliver full tumbling of coffee beans inside the chamber to eliminate uneven roasting.
- Front and rear bearings are constructed from food-grade 304 stainless steel, wear-resistant and convenient for regular lubrication maintenance.


2. High-Efficiency Fuel-Saving Gas Heating System
- Custom factory high-performance burner compatible with LPG, Natural Gas and Propane fuel types.
- Easy ignition and stable strong flame supply for steady drum heating.
- Multi-layer premium thermal insulation layer traps heat inside the drum to avoid heat loss and reduce fuel consumption.
- Independent hot air pressure gauge tracks real-time airflow pressure value under all working conditions. It solves inaccurate airflow control issues brought by blocked exhaust pipes, clogged fans, strong wind or heavy rain, enabling highly precise roasting parameter adjustment.
3. Integrated Roasting & Rapid Cooling Design
- Roasting and cooling functions run simultaneously to improve overall working efficiency.
- Separated independent chaff cyclone achieves thorough chaff collection and separation, avoiding chaff accumulation in the roasting chamber.
- Cooling tray adopts food-safe 304 stainless steel material, equipped with built-in stirring agitator and dedicated cooling mixing motor.
- Complete cooling of a full batch of roasted beans only takes 1–2 minutes.
- Special baffle plate installed at bean discharge position prevents hot beans from splashing out to avoid scald risks during unloading.


Intelligent PLC Touch Screen Control Panel
- Integrated touch control covers heating adjustment, timing, cooling, cooling stirring, hot air volume and drum rotation speed regulation.
- Supports storage and one-click repetition of custom roasting profiles for consistent roast results batch after batch.
- Adjustable parameter ranges:
- Drum Speed: 0–120 RPM
- Hot Air Output: 0–50 adjustable gears
- Heating Power: 0–50 adjustable gears
- Reserved USB data transmission port: Connect to PC to record all roasting curve data. Compatible with Artisan roasting software for professional data logging and roast tracking
5. Convenient Maintenance & User-Friendly Structure
- Large dedicated maintenance access door with matching key, allowing quick disassembly, cleaning and replacement of core components like gas burners without complicated disassembly work.
- Transparent sight glass, burner observation window and dedicated sampler spoon are equipped for real-time bean inspection during roasting. Real-time temperature values are displayed directly on the control panel.
- Four independent high-quality motors separately control drum rotation, hot air supply, tray cooling and cooling mixing for independent precise parameter tuning.
