An apparatus includes a body having a length extending from a first end to a second end. The body defines a bore extending through the entirety of the body and at least one of a plurality of grooves or holes around the bore. The body has a length that is dimensioned to be received entirely within a neck of a container.

A static homogenizing apparatus for blending a fluid additive with a polymer melt includes: (a) a homogenizing conduit; and (b) a plurality of homogenizing elements in the conduit for flow of the melted resin and fluid additive through the homogenizing elements in series. The plurality of homogenizing elements includes a plurality of mixing elements and at least one amplifier element. Each mixing element has a quantity of mixing channels passing therethrough, and each amplifier element has a quantity of amplifier channels passing therethrough. The quantity of amplifier channels is greater than the quantity of mixing channels.

A mixer assembly for mixing an injected reductant with an exhaust gas comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The reductant inlet is positioned on a first side of the tubular housing and oriented to direct injected reductant along an injection access that extends transversely to a longitudinal axis. A first flow guide element is shaped as a sheet including a first aperture extending therethrough as well as a surface facing upstream. Exhaust gas flowing through the first aperture is impinged by the injected redundant. A second flow guide element is shaped as a sheet, positioned downstream from the first flow guide element and fixed to the first flow guide element to define a mixing chamber between the first flow guide element and the second flow guide element in which the injected redundant and the exhaust gas mix.

A system for continuously processing a combination of materials includes a continuous process vessel having an outlet and one or more inlets. The continuous process vessel is configured to oscillate along an oscillation axis. An acoustic agitator is coupled to the continuous process vessel. The acoustic agitator is configured to oscillate the continuous process vessel along the oscillation axis. An outlet passage is in fluid communication with the outlet. At least a portion of the outlet passage or at least a portion of the continuous process vessel is disposed within a portion of the acoustic agitator.
