- Typical batch capacity
- For this class of equipment, batch capacities commonly range from 5kg to 7kg, suitable for small to medium production.
- Power supply
- Units of this type typically require a three-phase electrical supply, commonly 400V, 50Hz, with specific amperage varying by model.
- Heating method
- Roasters in this category often utilise gas (natural gas or LPG) for the main heating element, with electrical components for controls and motors.
- Cooling
- Integrated cooling trays with powerful fans are standard to rapidly cool roasted beans and prevent over-roasting.
- Chaff collection
- A separate husk (chaff) collector is typically included to remove the outer skin of the coffee beans during roasting, improving air flow and cleanliness.
- Footprint
- While specific dimensions vary, these roasters are generally compact, designed for spaces where floor area is a consideration.
- Control system
- Commonly features manual controls with analogue gauges, though some may have basic digital temperature readouts for drum and exhaust.
