- Typical batch capacity
- For this class of equipment, a 150kg nominal capacity is common, with some flexibility for larger batches depending on bean density and desired roast profile.
- Power supply
- Traditional roasters of this size typically require a robust three-phase electrical supply for motors and controls, alongside a gas supply for the burner.
- Heating method
- Units of this vintage commonly utilise direct gas-fired heating, providing efficient heat transfer to the roasting drum.
- Associated equipment
- A complete line commonly includes a cooling tray, green bean loader, destoner, and an integrated control panel for operational management.
- Footprint
- A full roasting line with ancillary equipment will require a substantial dedicated area, typically several square metres, for safe operation and maintenance access.
- Construction materials
- Roasters from this era are generally constructed from durable cast iron and heavy-gauge steel, built for longevity in industrial environments.
