  • Designed for reduced fibre loss, improved energy efficiency and increased reliability
  • Low maintenance machines increase runability
  • Global customers such as Bulleh Shah Packaging are convinced of efficiency gains and cost savings

Voith, one of the leading full-line supplier in the paper industry, presents its optimised LC (low-consistency) pulping system for recycled paper. The previous TwinPulp system has undergone extensive further development, with the focus on improving efficiency and reducing costs. Following the optimisation of the IntensaPump after the IntensaPulper IP-R, the IntensaMaXX and the IntensaScreenDrum, the revisions of all main components have been successfully completed. The high-performance OCC dissolution system, which meets the latest technological standards, is now available under the name BluePulp LC.

We are proud that we have been able to further develop our TwinPulp pulping system into the BluePulp LC, a product of the proven BlueLine product family. It now combines all the key economic and technological advantages that our BlueLine portfolio stands for: reduced fibre loss; low energy consumption; simple, safe operation; increased runability; and a robust, low-maintenance machine design.

Every component of BluePulp LC contributes to more efficient and reliable resolution. Compared to conventional LC pulpers, energy consumption can be reduced by up to 25 per cent with the eccentric IntensaPulper IP-R. The improved IntensaPump conveys the highly contaminated stock flow from the IntensaPulper IP-R to the IntensaMaXX disposal machine largely free of blockages, enabling energy savings of up to 30 per cent and reducing wear at the same time. IntensaMaXX allows for maximum contaminant contents, while the special shape of the housing suppresses the formation of spinning. The IntensaScreenDrum screening drum washes out rejects very efficiently, thanks to sophisticated spray pipes, and minimises fibre losses.

BluePulp LC can be integrated into existing stock preparation systems as well as newly configured systems. The response is impressive. For Bulleh Shah Packaging, the installation of BluePulp LC has been a valuable step.

“The Voith pulper is outclass. We get very convincing results. It delivers uniform mixing and separates reliably. After installing the IntensaPump and its back flushing sequence, we are running free of blockage issues and are 100 per cent satisfied with the performance. The IntensaScreenDrum also receives special recognition: I have never seen such a high-performance screen in my career. It completely removes plastics and supports us in reaching maximum yield after pulper slushing.

With the development of the BluePulp LC system, Voith once again underlines its goal to provide sustainable and resource-efficient solutions for paper production from a single source, thereby increasing productivity and profitability for its customers.
