Valmet fiber furnish analyzer measures wider range of properties

Valmet says its completely redesigned Fiber Furnish Analyzer takes advantage of its extensive field experience and new technology. The analyzer is designed to provide fast, precise on-line measurement of key fiber and furnish properties for paper, board and tissue makers.

New image analysis techniques enable automatic measurement of a wider range of furnish properties. Additional modules can be added to the platform, with standardized measurements of Canadian Standard Freeness or direct Shopper- Riegler as well as a chemistry module to monitor pH and conductivity. The analyzer is ideal for process control and, with the addition of a remote manual sampling station; it is also a laboratory tool providing fast, accurate analyses.

Rather than relying on infrequent and time-consuming laboratory tests, machine operators now have the information to act quickly and decisively. Better control of refining levels, monitoring of incoming pulp quality or fiber blend optimization are further improved with the built-in Valmet’s Data Modeler and Soft Sensor, which continuously predict pulp strength properties from a combination of measured properties.

“Operators can now see fiber development and (the) impact of process changes on pulp strength in real-time. Without waiting for physical tests, shift-to-shift quality variations can be greatly reduced to provide significant energy and raw material savings,” says Ismo Joensuu, product manager, analyzers & measurements, automation business line, Valmet.

With comprehensive self-diagnostics and Industrial Internet capabilities, including remote product and application support, measurement reliability is assured. The fiber furnish analyzer also enables operators to remotely activate the automatic collection of follow-up samples for later laboratory verification and automatic validation of pulp strength modeling.

Connections to existing and future mill systems are securely supported by versatile communication interfaces. The analyzer’s application areas have also been widened with a new sampler for coarse pulps and an optional de-foamer addition to improve measurement capabilities with certain grades of pulp.
