- Typical batch capacity
- For this class of equipment, batch capacities commonly range from 5kg to 60kg of green coffee beans per roast.
- Power supply
- Units of this type typically require a three-phase electrical supply, commonly 400V, 50Hz, with varying amperage depending on heating element and motor sizes.
- Heating method
- Roasters in this category often utilise gas (natural gas or LPG) for the main heating, with electrical components for motors and controls.
- Associated equipment
- A complete roasting line typically includes a roaster, cooling tray, destoner, afterburner, cyclone, chaff collector, and green bean loader.
- Control systems
- Modernised units, or those refurbished, commonly feature PID controllers or more advanced PLC-based systems for temperature and roast profile management.
- Footprint
- The overall footprint for a complete line, including ancillary equipment, can vary significantly but typically requires a dedicated space of at least 15-30 square metres.
