- Typical batch capacity
- For this class of equipment, a batch capacity of approximately 20-25 kg of green coffee beans is common.
- Power supply
- Units of this vintage and capacity typically require a 3-phase electrical supply, commonly 400V, 50Hz in the UK, for motors and heating elements.
- Heating method
- Gothot roasters of this era commonly utilise gas (natural gas or LPG) for the main roasting heat source, often combined with electric components for controls and ancillary functions.
- Cooling method
- Integrated cooling trays with forced air circulation are typically found on units of this type to rapidly cool roasted beans.
- Footprint
- A roaster of this capacity typically requires a footprint of around 2m x 1.5m, plus space for ventilation and bean storage.
- Construction materials
- Robust construction using cast iron and steel is typical for Gothot roasters, ensuring durability and heat retention.
- Control system
- Older units commonly feature manual controls for drum speed, airflow, and burner intensity, with analogue temperature gauges.
