- Typical batch capacity
- This '20Kg' model designation commonly refers to a nominal batch capacity of 20 kilograms of green coffee beans.
- Heating method
- Units of this type are typically gas-fired, often configured for LPG (propane) as mentioned, or natural gas.
- Power supply
- Electrical requirements for control systems and motors commonly range from single-phase 230V to three-phase 400V, depending on the specific model and region.
- Chaff collection
- An external cyclone, as described, is a standard component for separating and collecting chaff during the roasting process, improving air quality and roast consistency.
- Cooling system
- Integrated or external cooling trays are typically included to rapidly cool roasted beans, preventing over-roasting.
- Typical footprint
- For this class of roaster, a footprint of approximately 1.5m x 1m x 2m (LxWxH) might be expected, plus space for the cyclone and ventilation.
