the individualist
The PROBAT Jupiter coffee roasters are a unique all-rounder thanks to thier huge array of possible roasting times, extreme flexibility and robust designs. There are 4 versions offering different capabilities and batch sizes.
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 minimised by the roasting system’s insulation. The easy-to-access modular design leads to minimal maintenance, cleaning and repair time.

BENEFITS TO 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
PERFORMANCE DATA - Best Life-Cycle Costs and Performance
CONTROL
All JUPITER tangential roasters are equipped with the PILOT Roaster Excellence control system. In this context, high-quality hardware and software guarantee maximum production reliability. Customers can choose between various PLC-solutions and visualization concepts according to their individual demands.
- Fully automated PC-based control system
- Clear visualization and simple operation
- Recipe management with up to 999 user-definable recipes. Settings that have been found once are reproduced safely and automatically.
- Reflex Automatic function (optional): reproducibility of roasting profiles by eliminating external influences such as varying batch sizes, green-coffee moisture, or ambient temperature
- Reflex Extended function (Type JUPITER SY-LT): In addition to the functions of the Reflex Automatic target/actual values can be faster adapted
- Overview of all key roasting parameters and temperature curve
- 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
ENVIRONMENTAL & 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 standardised requirements.
- 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

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.
