The heart of PROBAT’s G Series drum roaster is a horizontal roasting drum, driven by a gearmotor. Shovel blades circulate the coffee beans during the roasting process. The flame of a burner generates the energy for the roasting air ,which is guided both through as well as around the roasting drum by means of flaps. As such, heat is applied through conduction via the bean’s contact with the roasting drum as well as through convection via the hot incoming air.
The PROBAT G Series roasters are all equipped with a user-friendly control panel for precise, consistent results.
Thermal or catalytic afterburners are available for pollution control requirements. Both systems can be applied to treat roaster and cooler air. PROBAT emission controls are designed to:
