PROBAT is the world's only supplier of patented centrifugal roasting technology where the beans aren’t mechanically moved. The rotating roasting bowl creates a centrifugal force moving the beans upwards in the dish and positioning them into the main hot air stream. The roasted goods are well blended in a gentle and uniform manner thanks to the vertical rotational movement combined with an outer lamellar ring.
SATURN achieves unique roasting results in the middle roasting time range. On the one hand, it offers a number of ways to influence the flavor, density and degree of extraction from the roasted coffee. On the other hand the thermal equilibrium which is reached quickly ensures that the bean-roasting process proceeds extremely gently.
The SATURN roaster minimizes heat losses, saves a great degree of energy and is friendly to the environment while also automatically regulating the cooling time. The air volume can be reduced to a minimum, while the integrated roasting air circulation ensures an optimum balance of energy. The compact system also provides another advantage: small spatial requirement.
The distinguishing characteristic of the PROBAT SATURN centrifugal roaster is the rotation of the roasting bowl which is equipped with a lamellar ring around the vertical axis. In this manner, the green coffee is mixed gently during the roasting process. Hot air is guided into the roaster through the center of the bowl, and as a result, the heat is transferred evenly and the beans are roasted homogeneously. The result is a particularly uniform bean appearance. In this context, the quantity of air needed for the roasting process can be reduced to an absolute minimum. The addition of water systematically ends the roasting process while simultaneously precooling the roasted coffee.
SATURN centrifugal roasters show their strengths in the medium roasting range between 5 and 10 minutes. The flexibility to change various key parameters makes it possible to fine-tune the aroma, density, and the extraction level of the roasted coffee.
SATURN centrifugal roasters offer these and many other benefits:
All SATURN centrifugal 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.
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.
