Automation of pulp testing with forming a hand-sheet is not so popular in Japan but pulp testing has been done manually by operators. Under the situation, it has been difficult to make pulp testing frequently due to limited number of shift operators and long testing time required. Furthermore, the difference among individual operators at measurement might influence on the results.
Pulp Expert (PEX) is the fully automated pulp testing system that was developed in Finland about 10 years ago. PEX measures rapidly more than ten kinds of physical and optical properties of pulp sample that is formed to sheet automatically in the PEX. Samples are taken automatically from up to 8 positions of process lines via sampling valves controlled by signal from PEX.
It allows mills to make pulp testing more frequently and consequently mills can keep good quality of their pulp, also it allows to consider saving manpower on each sift. At present PEX has been delivered more than 80 units in the world. PEX is receiving high reputation from users because of its good repeatability and good correlation with lab data.
