Abstract: The present invention relates to a straining device in association with the displacement of liquid through a pulp bed preferably in connection with the withdrawal of cooking liquid in a continuous digester (1) for producing chemical pulp, which straining device (2) is preferably rectangular and comprises a number of strainer-bars (3), arranged in parallel, which have been fixed to at least two rod elements (4, 5), which are placed transversely in relation to the lengthwise extension of the bar-strainers, the said rod elements (4, 5) being made of metal, preferably stainless steel, and having a strength value RP 0.2 at 100.degree. C. which exceeds 200 MPA, preferably 300 MPA, and more preferably 350 MPA, and the width of the said rod element (4) being less than 800 mm, preferably 650 mm, and more preferably 550 mm, so that the straining device becomes self-supporting.
