GEA has again proven the efficiency of its machinery following the successful deployment of a CF 8000 decanter at European wheat starch processors.
The installation of the starchMaster CF 8000 decanter is responding to the growing global market for starch and starch products.
According to Euromonitor, this market is expected to reach a volume of over $129 billion by 2030. The new decanter has been specially optimised for high-throughput starch extraction and gluten separation and is already being used successfully by European users following convincing tests.
The high-performance starchMaster CF 8000 can be used for both 2-phase and 3-phase processes and offers a capacity of 15-20 tonnes of wheat flour equivalents per hour.
The CF 8000 decanter comes standard with the GEA summationdrive, whose frequency-controlled motors automatically and seamlessly adjust the differential speed according to the solid load. Since the intensive starch processing is often associated with high differential speeds and torques of the decanter and thus with considerable gearbox loads, the starchMaster CF 8000 has been proactively equipped with a cooling system. This ensures reliable gear operation even under the most extreme conditions.
The CF 8000 decanter offers an optional active torque control (ATC) system. This GEA solution provides precise, automatic adjustment of the differential speed through active torque control to maintain the optimal operating point while avoiding stick-slip. This not only maximises solid yield but also minimises energy costs for thermal drying. ATC also significantly reduces the risk of machine damage from stick-slip, contributing to more efficient and sustainable production.
The starchMaster CF 8000 also features the new GEA varipond C system, allowing flexible adjustment of the separation zone within the decanter. This system is suitable for both 2-phase and 3-phase processes and enables quick response to changing feed conditions. With varipond, users can adjust the running decanter to changing requirements at any time, ensuring optimal separation results and stable solid discharge through variable pond depth.
The CF 8000 completes the package for this new decanter. By integrating the decanter into the cloud, operational data can be monitored in real time.
Through customised service level agreements (SLAs), GEA provides proactive service and maintenance with trained personnel to ensure maximum uptime and efficiency of the machines.
The stick-slip phenomenon is a detrimental effect that can occur in industrial machines like decanter centrifuges – irrespective of manufacturer and design – when the static friction between the solid bodies moving against each other is greater than the dynamic friction. If the slipping speed of the solid body becomes too slow, it gets stuck and needs additional energy to start slipping again.
The stick-slip effect cannot be detected from the outside and leads to increased fatigue and wear to machine components such as the bowl, scroll, gearbox, shafts and coupling. Stick-slip increases the risk of unplanned, expensive downtimes with costly repairs.
