Advantages

Maximum Reproducibility

The precise control of the air volume flow and the supply air temperature enables a controlled energy input into the coffee beans and guarantees reproducible roasting results.
Maximum Quality

The movement of the coffee beans on defined paths guarantees even mixing of the coffee beans and a homogeneous bean pattern.
Maximum Aroma Flexibility

The optional manual control of the air volume flow using the so-called aroma wheel enables maximum flexibility when developing different aroma profiles (G45 only).
Maximum Individuality

The customization of different design parts rounds off the classic look of the roasting machines and makes each one unique.

Built to solve. Designed to deliver.

With their round contours and clean lines, the PROBAT G Series roasters are as visually striking as they are technically advanced. Designed for medium-sized roasting operations, these machines combine a sophisticated design with exceptional roasting performance, making them the perfect choice for businesses that value form and function equally.

With batch sizes ranging from 45 to 150 kg, the G Series consistently produces high-quality roasting results. Heat is transferred primarily via convection, with a controlled flow of hot air supplied through the rotating drum. This method delivers uniform bean development and excellent reproducibility across batches.

For added flexibility, the G45 model — visually aligned with the iconic UG series — offers manual airflow control, enabling roasters to create unique profiles and fine-tune flavour development. Standard features across all G models include the automatic emptying of the bean container, roasting drum and cooling sieve, which streamlines workflow and boosts efficiency.
