- Typical capacity
- For this class of equipment, batch capacities commonly range from 30kg to 60kg, allowing for significant production volumes.
- Power supply
- Units of this type typically require a three-phase electrical supply, commonly 400V, for motors and controls, alongside a natural gas connection for the burner.
- Heating method
- Probat GG series roasters are traditionally gas-fired, utilising direct flame or hot air for efficient bean roasting.
- Control system
- While vintage, many units are retrofitted with modern roast profiling software, offering precise control over temperature and time.
- Ancillary equipment
- Roasters of this size typically include a destoner, cyclone for chaff collection, and an afterburner for emissions control.
- Footprint
- The overall footprint, including ancillary equipment, requires a dedicated industrial space, typically several square metres.
- Construction material
- Units are generally constructed from robust materials such as cast iron and steel, ensuring durability and consistent thermal performance.
