The drum roasting process in detail

The heart of PROBAT’s P60 drum roaster is a horizontally lying roasting drum which is  equipped with a rotary drive. 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.

Environment and Cost-Effectiveness

Different PROBAT systems make it possible to clean the thermal energy released during the roasting process. They are specifically tailored to the respective roasting process.

  • reduction of visible roasting exhaust
  • reduction of emissions and adherence to local thresholds through modular exhaust air treatment systems
  • minimal heat loss due to particularly well-insulated roasting system

PROBAT safety technology goes far beyond standardized requirements. We offer safety components that guarantee maximum process security.

  • ensuring the functional safety of your processing systems
  • maintenance-friendly safety components
  • battery and water buffer increase operation safety (P60 PRE)
