After the roasting process the beans are ground. This critical process must be as homogeneous and gentle as possible. The best flavor can only be achieved later if the best beans are combined with perfect roasting and the right grinding process. The grain size and density determine how the coffee reacts during brewing.
The compactly designed PROBAT standard and special two-stage or three-stage grinders are configured to grind beans gradually. Depending on the model, it’s possible to process up to 4,000 kilograms per hour (kg/h) (with special grinders, up to 2,570 kg/h). A compressor is also integrated for over 30% more compression. If that’s not enough, an additional compressor can be connected separately. (Remote) computer-controlled operations offer a high degree of safety, control, and consistent results.
The clear difference
The PROBAT grinders are designed to last a long time with little need for maintenance. Sound workmanship ensures wear-resistant operation over the long run with no interruptions. The split roller bearing housing makes it possible to exchange rollers easily in case of a fault. The specially designed profiles can be repeatedly refurbished if necessary.
Closed, dust-proof housings and special protection mechanisms against contamination by foreign bodies protect these grinders. Special guiding plates with polished surfaces prevent deposits from forming. Effective cleaning systems stop the build-up of products inside the grinders. The easy-to-access cleaning ports feature a practical and user-friendly design.
Experts at work
The special grinders are even more sophisticated. . Frequency-controlled motors in each grinder propel the large, water-cooled grinding rolls. The grain spectrum can specifically be influenced by individually controlling the relative speed of the grinding rolls, making it possible for the grinders to master even the most difficult of tasks, such as products for capsules and ultra-fine grinds. Their modular design makes it possible to adapt the number of rolls to the requirements of the coffee. The motor-driven grinding gap adjuster simplifies the configuration and calibration of the roller gap. A second outlet without a densifier allows the extraction of uncompacted ground coffee.
All PROBAT roll grinders are equipped with a water-cooled turbo mixer that specifically crushes residual chaff once again and homogeneously mixes the entire product. The densifier attached to the grinder’s outlet can compact the coffee to a constant level, if so desired. With the PROBAT roll grinder series, we offer every type of grinder for your individual requirements.
While the 500 series’ operating range stretches from a coarse grind for filter coffee to the finest espresso grind, the 300 series was also designed for grind levels up to a microfine grind. PROBAT roll grinders offer the following benefits:
All PROBAT roll grinders are equipped with the PILOT Grinder Excellence control system. In this context, high-quality hardware and software guarantee maximum production reliability.
PROBAT roll grinders are high performance grinding solutions that can be used for specific applications and recipes. They are flexible, offer constant, high-quality results and guarantee process stability.
PROBAT safety technology goes far beyond standardized requirements. We offer safety components that guarantee maximum process security.
