The heart of PROBAT’s R Series drum roaster is a horizontal roasting drum, directly driven by a gearmotor. Paddles in the drum 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 mainly through convection via the hot incoming air as well as through conduction via the bean’s contact with the roasting drum.
The PROBAT R Series roasters are all equipped with a user-friendly control panel for precise, consistent results.
Thermal or catalytic afterburners as well as flameless regenerative afterburners for the treatment of roasting and cooling exhaust streams.
PROBAT safety technology goes far beyond standardized requirements. We offer safety components that guarantee maximum process security.
