Patent number: 7985019Abstract: A method and an apparatus for continuously mixing two flows, a first, larger flow and a second, smaller flow. The second flow is introduced counter-directed into the first flow. The apparatus comprises a T pipe where a first connection constitutes an inlet for the first flow. A second connection, at 180° in relation to the first connection, constitutes an inlet for the second flow. The second flow is led into the first flow through a conduit within the T pipe. The first connection is provided with a conical portion in which are provided a number of holes, so that the first flow is throttled and divided up into a plurality of subflows immediately before the mixing operation. A third connection is oriented at 90° in relation to the other connections and constitutes an outlet for the intermixed flows, which implies that the intermixed flows are caused to change direction immediately after the mixing.Type: GrantFiled: April 8, 2004Date of Patent: July 26, 2011Assignee: Tetra Laval Holdings & Finance SAInventors: Eric Lundgren, Bengt Palm
