Px 120
DRUM ROASTER

In a class of its own

The all new Px 120 drum roaster is a unique fusion between cutting-edge engineering and classic design. Almost 80% of the machine components are completely new developed. All parts are available as 3D data with which a full virtual plant can be created.

By means of CFD (Computational Fluid Dynamics) analytics the roasting system has been optimized to increase coffee quality and energy efficiency. The forward-thinking new partial recirculation system significantly reduces energy consumption. A high-efficiency cyclone with optimized flow processes ensures an effective chaff separation and fast and clean disposal. The trailblazing intuitive control solution guarantees highly efficient processes, increased quality and productivity.

The drum roasting process in detail

The heart of PROBAT’s Px 120 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.

Benefits for your coffee

With an extended batch size range between 60 and 120 kg and roasting times between 6 and 20 minutes, the Px 120 drum roaster guarantees more flexibility while maintaining a constantly high coffee quality. The Px 120 roaster offers this and many other benefits:

Reduced exhaust air volume due to partially recirculating system
Fewer deposits due to optimzed feed hopper
Optimized chaff separation, less dust deposits and increased cleaning results due to high-efficiency cyclone
Lower energy consumption and more flexibility due to frequency converters for all drives as standard
Increased roasting quality through optimized drum geometry
Increased flexibility through extended batch size range
Increased cooling performance

Environment and Cost-Effectiveness

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

Energy savings through partial recirculation of roasting exhaust air
Energy savings and increased production through green coffee preheating (optional)
Reduction of product-specific odors and visible roasting exhaust gases
Reduction of emissions and adherence to local thresholds through modular exhaust air treatment systems
Maximum cleaning efficiency thanks to the Proforte exhaust air treatment system (flameless, renewable, thermal oxidation)
Energy monitoring for cost transparency
Heat recovery through use of heat exchangers
Minimal heat loss due to particularly well insulated roasting system
Thermal cleaning cuts human resource costs and saves time
