- Typical capacity
- For this class of equipment, a 15kg batch capacity is common, allowing for moderate production volumes.
- Power supply
- Units of this type commonly require a 3-phase electrical supply for motors and heating elements, alongside a gas supply for the burner.
- Heating method
- Typically direct flame gas-fired, with hot air convection assisting the roasting process.
- Cooling system
- Most units include an integrated cooling tray and fan to rapidly cool roasted beans, preventing over-roasting.
- Chaff collection
- Equipped with a cyclone separator for efficient collection of chaff, which is a common feature for safety and cleanliness.
- Footprint
- The physical footprint for a 15kg roaster, including the cyclone, typically requires a dedicated area of approximately 2-3 square metres.
- Control system
- Commonly features manual or semi-automatic controls for drum speed, airflow, and temperature, with digital readouts.
- Construction material
- Typically constructed from robust materials such as cast iron and stainless steel for durability and heat retention.
