Title: Per-Anders Ottosson: Innovator in Digester Vessel Technology
Introduction
Per-Anders Ottosson is a notable inventor based in Skoghall, Sweden. He has made significant contributions to the field of digester vessel technology, particularly with his innovative designs that enhance efficiency and reduce costs.
Latest Patents
Ottosson holds a patent for a "Profile bar screen for digester vessels." This invention relates to an improved profile bar screen designed for draining treatment liquor from a suspension of comminuted cellulose material and treatment liquor in an essentially cylindrical digester vessel. The design features horizontal support arches with integrated support shoulders located only at the outer ends of the support arch. This innovative approach allows the support shoulders to rest against the inside of the vessel wall, combining techniques from self-supporting screens with support members of weaker screen designs. This design avoids the need for additional welds in the classified pressure vessel wall of the digester. The installation of new screens in compartments previously equipped with blind plates can be done quickly and at lower costs, resulting in shorter downtime for the digester.
