For industrial coffee roasters and commercial brands, transitioning to a large scale coffee roasting line is a major financial step. At this volume, you face highly stressful operational challenges that small shop roasters never experience: How do you keep the flavor profile identical across 5 tons of coffee a day? How do you eliminate dangerous chaff fires? And how do you stop your staff from burning out from heavy manual lifting?

If your current setup relies on human operators manually adjusting gas valves, timing batches by hand, or hauling heavy green bean bags up ladders, you are risking massive product waste and high labor costs. Our 120kg automatic coffee roaster production line is engineered precisely to solve these commercial pain points.

Solving Your 3 Biggest Commercial Roasting Problems

1. The Problem: Inconsistent Flavors Between Batches
The Solution: When roasting 120kg at a time, a 5-second delay in dropping the batch can ruin an entire production run. Our fully automated PLC control system eliminates human error. Once your master profile is established, the system automatically manages the gas burner and airflow to track your Rate of Rise (RoR) perfectly. It drops the beans into the cooling tray at the exact target temperature or development time ratio (DTR) automatically, guaranteeing identical flavor profiles from Monday morning to Friday night.

2. The Problem: Heavy Manual Labor and Production Bottlenecks
The Solution: Moving hundreds of kilograms of coffee beans every hour causes staff fatigue and dangerous workplace clutter. Our integrated line replaces physical labor with automation. Green beans are drawn from floor hoppers into the roaster via a pneumatic vacuum conveyor. After roasting, the beans drop into a high-capacity forced-air cooling tray, and are immediately conveyed into an automated coffee bean destoner to strip out rocks and debris. One single operator can manage the entire system from a central touchscreen panel.

3. The Problem: Chaff Overheating and Fire Risks
The Solution: Roasting 120kg of coffee creates an enormous volume of flammable chaff and oil buildup. A minor lapse in maintenance can trigger an exhaust blockage or fire. To solve this, our industrial lines are engineered with high-precision thermal sensors inside both the roasting drum and the cyclone chaff collector. These sensors monitor internal temperatures 24/7. If a temperature spike is detected, the system instantly triggers a visual and audible alarm on the PLC panel while automatically shutting off the gas supply and adjusting the airflow to safely isolate the heat, preventing a fire before it can spread.

High-Volume Engineering Built for Your Bottom Line

A large scale coffee roasting line must be tough enough to handle continuous, multi-shift schedules without breakdown.

No Scorched Beans: We use a precision-engineered, double-walled carbon steel drum. The outer layer shields the beans from direct burner flames, while the inner layer provides deep, uniform convective heat. This eliminates “facing” or scorching, allowing you to run back-to-back batches safely.

Rapid Cooling to Lock in Aroma: Leaving hot beans in a sluggish cooling tray cooks them past their intended profile, flattening the flavor. Our high-pressure suction fans pull ambient air through the cooling bed, dropping the bean temperature to a stable level in under 3 minutes to lock in delicate aromatic oils.
