Abstract: A decanter centrifuge is disclosed for separating a liquid feed mixture into constituent parts. The decanter centrifuge includes a bowl assembly mounted for rotation about a longitudinal axis. Opposite ends of the bowl assembly are rotatably supported by first and second bearings. A motor is engaged with one end of the bowl assembly for rotating the bowl about the longitudinal axis. A screw conveyor is coaxially mounted within the bowl with a conveyor shaft attached thereto. A gear box is located between the second bearing and the bowl and includes a transmission engaged to the shaft. The transmission rotates the conveyor at a relative speed with respect to the bowl. A plurality of circumferentially spaced posts mount the gear box to the bowl, spacing the gear box apart from the bowl. Effluent discharge ports on the bowl discharge effluent into the space between the bowl and the gear box.

Abstract: A decanter centrifuge is defined for separating a heavy phase material from a liquid within a feed mixture. The decanter centrifuge includes a bowl rotatable about its longitudinal axis for separation of the heavy phase material from the liquid feed mixture due to centrifugal force. The bowl typically includes a cylindrical portion and a frusto-conical portion at one end. A solids discharge is provided in the restricted end of the frusto-conical bowl portion. A screw conveyor is coaxially mounted for rotation within the bowl, having a spiraled conveyor flight extending radially outwardly to a position adjacent the inside wall of the bowl. The conveyor is adapted to rotate at a relative speed with respect to the bowl for conveying separated heavy phase material toward the heavy phase discharge. A baffle in the form of a disc extends radially outwardly from the conveyor hub and is adapted to project into the separated heavy phase material being conveyed along the bowl wall.

Abstract: The present invention is directed to a mist pump for a conveyor of a decanter centrifuge. The mist pump is incorporated into the feed chamber and prevents mist from leaving the feed zone and building up a layer of feed in the conveyor hub. The mist pump includes a plurality of vanes attached to, extending radially inward from and spaced about an interior surface of the sidewall of the feed chamber. The mist pump also includes a ring positioned coaxially about the longitudinal axis, attached to each of the pump vanes and spaced radially inward from the sidewall to provide a plurality of return openings defined by the ring and the sidewall.

Abstract: Containers having improved ability to deliver materials, especially comestibles into restricted containers are provided. Such containers, preferably of the type normally denominated as “measuring cups” preferably comprise elongated snouts projecting upwardly and outwardly from their top and side surfaces so as to facilitate such transfer.
