- Typical capacity
- For this class of equipment, capacities commonly range from 60 kg to 120 kg per batch, depending on the specific model variant and desired roast profile.
- Power supply
- Units of this type typically require a three-phase electrical supply, commonly 400V, 50Hz, for motors and controls, in addition to a natural gas or LPG supply for the burner.
- Heating method
- Petroncini TTA series roasters are typically indirect hot air roasters, providing consistent and controllable heat transfer to the beans.
- Footprint
- A complete roasting line, including roaster, cooling tray, cyclone, and afterburner, will require a significant industrial footprint, typically several square metres, with adequate ventilation and access for maintenance.
- Control system
- Modern commercial roasters like the TTA60 commonly feature PLC controls for automated roasting profiles, temperature management, and safety interlocks.
- Fuel type
- This specific unit is noted to run on natural gas; however, other units in this range may be configurable for LPG or other fuel sources.
