Right: Blue Air Systems says its BBX module offers energy savings of 50–70% in pellet drying
The main energy savings come from the drying method used. Unlike conventional strategies, it needs no regeneration energy. The dryer not only enables a constant dew point without fluctuation, but also needs no cooling water or molecular sieve during operation. It only requires an air filter change after a long period of use. The compact modules can be used for a range of hopper sizes up to 10,000 kg/h, for PET applications up to 1,000 kg PET/h as standard. Installation is straightforward thanks to a plug-and-play design and can be completed in one day. �

Coperion showed an extended portfolio of feeding and weighing technologies at K2025. The company plans to harmonise its expanded feeder product line with the Coperion K-Tron SmartConnex Feeder Control. This includes integrating the redesigned KCM-III Control Module and K-Vision Line Controller that offers a variety of connectivity options. New additions to the Coperion portfolio include

allowing faster decisions during production
the AccuRate Series 602 volumetric feeder and the MechaTron Coni-Flex single screw feeder that is suited to either volumetric or gravimetric feeding applications. Both feature vinyl hoppers that are agitated on the exterior by two paddles. Visitors will see how the MechaTron’s design allows for complete disassembly without removing upper extension hoppers, bins, bulk bags or IBS – reduc- ing maintenance time and operational costs. Another feeder for the plastics recycling industry is the Coperion K-Tron K3-V200 vibratory feeder that delivers high-accuracy gravimetric feeding of free-flowing fragile materials such as flakes and glass fibres. Its drive technology minimises mechanical wear and energy consump- tion while allowing rapid product changeovers with a quick-release tray mechanism. In addition, the S60 single
screw feeder was on display. Its modular design ensures durability and hygiene, with
straightforward disassembly and easy screw replacement for maintenance convenience. It is available in both volumetric and gravimetric configurations, offering flexible options for recycling and processing applications. �

Kreyenborg showed both a continuous system and a batch version of its infrared rotary drum (IRD) at K2025. To fully demonstrate the IRD, a large monitor
provided a view into the interior, showing how the material in the rotating drum behaves under IR light. The company also showed mixers, special silos and extruder feeding systems. The IRD also has a new control system. The 7- and 15in monitors have been given a graphical user interface and the software is more user- friendly, it says. Greater transparency is now possible, allowing the user to make faster, more accurate decisions during production. The new panel with the graphical software will be part of every new IRD system in the future. Kreyenborg offers a retrofit solution for the IRD called the Eco-Booster. Heat from the IR rotary tube is used to preheat the raw material waiting to be supplied. This can save up to 10% of energy use or increase throughput of the material by up to 20%, meaning the system can pay for itself after about one year. �
