Industrial Coffee Roaster – Automatic Drum Coffee Bean Roasting Machine For Coffee Factory Production

For coffee brands and large-scale roasting factories, stable batch quality and high throughput are the core competitiveness. Our industrial coffee roaster, mainly drum-type roasting equipment, is designed for mass production of roasted green coffee beans. It can precisely control temperature, airflow and roasting time to produce consistent light, medium and dark roasted beans. We supply multiple batch models ranging from 10kg to 120kg per batch, supporting medium coffee roaster workshops and full-scale industrial coffee manufacturing plants. Both gas and electric heating versions are available for different factory energy conditions.

What Is An Industrial Coffee Roaster Used For?

The industrial coffee roaster turns raw green coffee beans into aromatic roasted coffee beans through controlled thermal reaction. During roasting, beans go through drying, Maillard reaction, first crack and second crack. The machine is widely used for specialty coffee factories, commercial roasting enterprises, coffee bean packaging manufacturers and large coffee brands. Compared with small commercial roasters, industrial models support continuous batch production, stable flavor repeatability and lower labor cost for mass orders. It can process Arabica, Robusta and blended green coffee beans.

Working Principle of Industrial Drum Coffee Roaster

This drum industrial coffee roaster relies on combined conduction and convection heating. Green beans are loaded into the rotating stainless steel drum. The drum keeps tumbling beans evenly to avoid local scorching. Operators set roast profiles on PLC panel to control inlet temperature, drum rotation speed and exhaust air volume. When roasting finishes, beans are quickly discharged into the cooling tray. Fast cooling stops chemical reactions instantly to lock flavor. Chaff separated during roasting is collected by the exhaust system to keep workshop clean.

Main Components of Industrial Coffee Roasting Machine

Rotary Roasting Drum & Heating System

The roasting drum is made of thick heat-resistant stainless steel. Gas burner or electric heating module provides stable and adjustable heat source. Uniform heat distribution ensures every bean gets equal heating, reducing defective roasted beans.

Chaff Collection & Rapid Cooling Tray

Built-in cyclone chaff collector captures silver skin chaff generated during roasting, avoiding dust pollution. The large cooling tray with strong air cooling can drop bean temperature rapidly within 3–5 minutes after roasting to stop over-roasting.

PLC Touchscreen Control System

The intelligent PLC touch screen stores multiple roast profiles. Users can save recipes for different bean origins and roast levels. Real-time data including bean temperature, exhaust temperature and roast time can be recorded and exported for quality traceability.

Key Benefits of Our Industrial Coffee Roaster

Precise temperature control ensures consistent flavor across every batch. Stainless steel contact parts keep coffee pure without contamination. Low noise and good sealing design reduce heat loss and save energy. Automatic roast profile storage makes operation easier for new operators. The whole machine has stable structure, low failure rate and easy maintenance. We can customize exhaust, automation and connection with downstream bean cooling, sorting and packaging equipment. The machine supports long-hour continuous batch operation for large daily output.

Available Capacity & Heating Options

Standard batch sizes: 10kg, 20kg, 30kg, 60kg, 120kg per batch. Two heating types: LPG gas heating and electric heating. Gas heating is more cost-effective for large-volume roasting; electric heating suits factories with strict emission requirements. We also provide auxiliary equipment including green bean feeder, destoner, bean cooler and automatic packaging machine to build full coffee roasting production line. Our engineers provide installation guidance, operation training and long-term spare parts support.
