  • Profile bar screen for digester vessels
    Patent number: 8980061
    Abstract: The improved profile bar screen is for draining treatment liquor from a suspension of comminuted cellulose material and treatment liquor in an essentially cylindrical digester vessel. The profile bar screen is designed with horizontal support arches that have expansion slots allowing the otherwise rigid structure of the support arches to flex and adapt to any unevenness of the vessel wall, thus allowing support shoulders to rest against the inside of the vessel wall.
