- Typical capacity
- This unit is specified at 15 kg per batch, which is common for small commercial roasters.
- Power supply
- For this class of equipment, a 3-phase electrical supply (e.g., 400V/50Hz) is typically required for heating elements and motors, though smaller auxiliary components may use single-phase.
- Heating method
- Coffee roasters of this size commonly utilise gas (natural gas or LPG) for the primary heat source, often supplemented by electric elements for precise temperature control.
- Cooling system
- An integrated cooling tray with an agitator and fan is standard to rapidly cool roasted beans and prevent over-roasting.
- Dimensions
- Footprint for a 15 kg roaster typically requires a dedicated space, often around 1.5m x 1m, plus clearance for maintenance and ventilation.
- Chaff collection
- An external or integrated chaff collector is essential for safety and cleanliness, removing the husks separated during the roasting process.
- Control system
- Units of this type commonly feature manual and/or semi-automatic controls for drum speed, airflow, and temperature, with digital readouts for monitoring.
