JUPITER
Tangential Roaster

The individualist among the roasters

The JUPITER is a unique all-rounder thanks to its huge array of possible roasting times, extreme flexibility and, last but not least, robust design: All types and blends of coffee can be roasted as you desire, making the tangential roaster perfect for meeting market requirements for greater variety.

The JUPITER roaster is internationally unrivalled when it comes to optimally roasting in the shortest possible time, no matter the quality of the green coffee. Precisely controlled and tangentially supplied roasting air, combined with the mechanical movement of coffee beans by a shovel mechanism with variably controllable speed, ensures heat is ideally transferred from the surface of the beans to their core to ultimately achieve consistent color and moisture content.

The closed roasting container even permits the gentle processing of batches of non-uniform coffee and of the smallest beans. Precisely timed addition of water ensures that the roasting process is finished on point in a controlled manner while also pre-cooling the coffee. The JUPITER roaster guarantees unrivaled product diversity and a stable roasting operation right from the get-go.

Energy loss is also minimized by the roasting system’s insulation. The easy-to-access modular design leads to minimal maintenance, cleaning and repair time.

The Tangential Roasting Process

The heart of PROBAT’s JUPITER series tangential roaster is a closed and stationary roasting chamber. Specially developed, rotating shovels move and mix the coffee beans around the drum. The flow of hot incoming air transmits the heat onto the beans through convection. The combination of controlled roasting air and mechanically mixed coffee beans creates the perfect transition between the temperature of the bean’s surface and its core. The flow of incoming air can be reduced to a minimum without affecting the movement of the coffee. The addition of water systematically ends the roasting process while simultaneously precooling the roasted coffee.

Benefits for your coffee

The roasting times of the JUPITER tangential roasters lie between 1,5 and 18 minutes. Also within shortest roasting periods perfect and reproducible results are achieved. Its flexibility makes the JUPITER tangential roaster an all-rounder that roasts every coffee with the desired profile. JUPITER tangential roasters offer these and many other benefits:

Perfect roast of both whole beans and crushed coffee
Uniform bean appearance and homogeneous roast through the application of heat via convection
Reliable production from light to extremely dark roast colors
Maximum range of density and volume for the produced roasted coffee
The flexible adjustment of various key parameters makes it possible to systematically affect the coffee’s flavor
Rapid recipe changes
Short heating-up time
Emptying into the cooler in a matter of seconds
Extremely rapid and uniform cooling, even with short roasting times
Highly uniform color- and moisture level

All data relevant to production is saved, allowing it to be accessed and analyzed at any time
Transparent presentation of the system’s operating status in real time
Can be operated directly at the roaster or centrally from a control room

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

Energy savings through recirculation of roasting exhaust air
Energy savings and increased production through green-coffee preheating
Reduction of product-specific odors and visible roasting exhaust
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 the use of heat exchangers
Minimal heat loss due to particularly well-insulated roasting system
Thermal cleaning cuts human resource costs and saves time
