New sensors for rapid evaluation of high-yield pulp attributes
Most high yield pulp mills produce various grades of pulp and experience frequent grade changes on their production lines. In order to maximise production yields and maintain quality, characterisation of pulp samples must be conducted and related back to the line in a timely fashion.
In an effort to accelerate the pulp characterization process, FPInnovations has launched a project to develop and commercialise technology that would allow determination of key pulp attributes by performing measurements directly on the pulp, thus eliminating the need for the preparation of handsheets.
The project has focused on the development of a sensor based on near infra-red (NIR) spectroscopy, to measure key attributes of high yield pulp accurately and quickly, despite variations in moisture content, wood species, and pulp grade.
