An apparatus for promoting a mass transfer reaction having a flow distributor and a drive unit. The flow distributor has a top end surface, a bottom end surface and a peripheral surface that are axisymmetric with respect to a rotation axis. The flow distributor is configured to submerge in a fluid medium and to generate a flow of the fluid medium through at least one of the top end surface and the bottom end surface and through the peripheral surface by rotating around the rotation axis. The drive unit is configured to move the flow distributor perpendicular to the rotation axis.

A blender system includes a blender tub, the blender tub defining a mixing chamber, an interior, and an upper opening. In addition, the blender system includes one or more blender paddles positioned within the mixing chamber. Further, the blender system includes a multi-tiered dispersion adapter positioned within the blender tub, the multi-tiered dispersion adapter including plates arranged at an angle to a horizontal plane of the blender tub's upper opening.

An aftertreatment system comprises: a housing, a SCR system disposed in the housing. A mixer is disposed upstream of the SCR system and includes: a hub, a tubular member disposed circumferentially around the hub and defining a reductant entry port, and plurality of vanes extending from the hub to the tubular member such that openings are defined between adjacent vanes. The plurality of vanes swirl the exhaust gas in a circumferential direction. A reductant injector is disposed on the housing upstream of the SCR system along a transverse axis and configured to insert a reductant into the exhaust gas flowing through the housing through the reductant entry port. The reductant is inserted at a non-zero angle with respect to the transverse axis opposite the circumferential direction to achieve virtual interception. A mixer central axis is radially offset with respect to a housing central axis of the housing.

A mixing vessel for a frozen drink maker is described. The mixing vessel includes a curved sidewall defining a substantially cylindrical vessel chamber therein. The vessel chamber includes a front, a rear, a right side, a left side, and a top. The mixing vessel also includes at least one internal baffle configured to control slush flow within the vessel chamber. The at least one internal baffle may be a corner baffle positioned at the front top of the vessel chamber on either the right side or the left side, a side baffle extending laterally along the vessel chamber from the front to the rear, and/or a front baffle positioned at the front of the vessel chamber extending across the top from the right side to the left side.

A mixing vessel for a frozen drink maker is described. The mixing vessel includes at least one curved sidewall defining a vessel chamber that is at least partly cylindrical configured to receive a drink product to be processed. The vessel chamber includes a front, a rear, a right side, a left side, a top, and a bottom, and the vessel chamber includes at least one asymmetric wall portion proximate to at least one of the front or the top of the vessel chamber. The at least one asymmetric wall portion is configured to promote slush flow within the vessel chamber.

A mixer and a method therein, including feeding a rotating flow of exhaust gas in a mixing pipe towards a turning end of a mixing chamber; dosing reactant by a doser against the rotating flow around a centreline of the mixing pipe; maintaining a guide around the doser such that a front face of the guide faces the rotating flow, and the guide defines a central opening surrounding the doser; guiding a side flow out of the rotating flow to a carrier flow around the doser via the central opening; and inhibiting by the guide turbulence from being transferred from the side flow to the carrier flow.

An aeration plate is provided, including an aeration top plate portion and a side baffle portion. The aeration top plate portion is scattered with a plurality of aeration holes, such that the aeration top plate portion and the side baffle portion cooperate to form an aeration member. A fruit and vegetable cleaning machine is provided, including a machine body. The machine body is provided with a cleaning tank with a top opening, and the cleaning tank is provided with the aeration plate at an inner bottom wall, such that an area enclosed by the aeration top plate portion, the side baffle portion, and the inner bottom wall forms a first dissolving zone for gas and water, and a second dissolving zone for bubbles and water is formed between a periphery of the aeration plate and the cleaning tank.

A multi-component fluid mixing device for mixing two or more fluids which can be used with an applicator tool, such as a spray gun. The mixing device is used with a removable cartridge that is pressure fitted into the body of the mixing device using an actuation mechanism that elevates a cartridge engagement base to create a fluid-tight seal.

A system for preparing a polymeric mixture includes: a containment device configured to distribute dry polymeric materials; a receiving chamber in fluid communication with the containment device; a wetting bowl; a dispersing channel; and a mixing chamber connected to the dispersing channel. A method of preparing a polymeric mixture includes distributing water and dry polymeric materials through the various components of the system and mixing the materials with the mechanical mixing device.

A mixing vessel comprises a top portion (12) on an inverted conical middle portion (14) and a mixing chamber (16) below the middle portion. A launder (28) surrounds the upper part of the top portion. Solution from the launder is led to a vertical pipe (46) including a motor driven impeller (42) down to the level of the mixing chamber. Two feed pipes (47, 48) lead from the vertical pipe to enter the mixing chamber tangentially in opposite directions.
