<p>[Problem] To provide a digester vessel, whereby it becomes possible to provide a proper flow rate over the entire surface of a solid carrier in the vessel, to maintain uniform mixing performance in the vessel, and to prevent the formation of precipitates at the bottom part of the digester vessel with an extremely low power. [Solution] A digester is equipped with: a cylindrical solid carrier (3) which extends in the vertical direction and is immobilized in such a manner that a gap (6) is formed between the solid carrier (3) and the inner wall of a vessel (2) and gaps (7, 8) are formed respectively between the bottom part of the vessel (2) and the solid carrier (3) and between the top part of the vessel (2) and the solid carrier (3), and which has a through-hole that extends in the vertical direction; a stator vane (11) which is arranged at the bottom part of the vessel (2) and extends radially; and a rotor vane (13) which is arranged above the solid carrier (3) and in the vicinity of the lower part of the liquid level.</p> |
