  • Patent number: 8628802
    Abstract: The invention concerns a process for the continuous treatment of an emulsion and/or a micro-emulsion assisted by an “expanded liquid” for the production of micro- and/or nano-particles or micro- and/or nano-spheres containing one or more active ingredients. In particular, a liquid solvent expanded by compressed or supercritical CO2 is contacted with an O/W emulsion, or alternatively a W/O emulsion or multiple emulsions, formed by an external phase that is itself a liquid expanded by compressed CO2. The expanded liquid forms a solution with the dispersed phase of the emulsion and extracts it inducing the formation of the desired particles of the dissolved compounds. The process is carried out in a counter-current packed column wherein the expanded emulsion is fed from the top, while the expanded liquid is fed from the bottom. Thanks to the presence of the expanded liquid, any deposition of the solid particles produced on the packing elements is avoided, thus preventing any column blockage.

  • Patent number: 8430558
    Abstract: A micromixing apparatus includes a mixing microchannel formed in a top surface of a substrate having a channel length and a variable channel width defined by a first sidewall surface and an opposing second sidewall surface. The channel width varies from a minimum channel width h to a maximum channel width H in a ratio of H:h?1.1:1.0. A first inlet is for injecting a first fluid into the mixing microchannel and a second inlet for injecting a second fluid into the mixing microchannel. The first and second fluid flow in a flow direction in the mixing microchannel along the channel length. The first sidewall surface includes first curved surface portions and the second sidewall surface includes a second curved surface portions. The plurality of first curved surface portions and plurality of second curved surface portions are non-overlapping to provide the variable channel width.

  • Publication number: 20130077433
    Abstract: A blender includes a container having a plurality of substantially triangular shaped ribs projecting into a processing zone of the container. The plurality of spaced ribs each include a width and a depth that taper from a top end section adjacent a teardrop shaped opening of the container to a more narrow bottom end section adjacent a bottom wall of the container. A side wall of the container continuously tapers from the teardrop shaped opening to a substantially square shaped bottom end portion including first, second, third and fourth side wall sections connected to one another at respective rounded corners. A blade assembly is coupled to the container and includes a plurality of blades angled at different planes with respect to a horizontal plane. Each of the blades includes a beveled leading edge, resulting in a downward suction force that draws ingredients down into the blade for processing.

  • Publication number: 20130077434
    Abstract: Embodiments of the subject invention are directed to methods and apparatus for inducing mixing in a fluid using one or more plasma actuators. In an embodiment, a pair of electrodes is positioned near a fluid and a voltage potential is applied across the pair of electrodes such that a plasma discharge is produced in the fluid. In an embodiment, the plasma discharge creates turbulence in the fluid thereby mixing the fluid. In an embodiment, flow structures, such as vortices are generated in the fluid. In an embodiment, the fluid is mixed in three dimensions. In an embodiment, a plurality of fluids are mixed. In an embodiment, solids are dispersed in at least one fluid. In an embodiment, heat or other properties are dispersed within at least one fluid. In an embodiment, at least one of the pair of electrodes has a serpentine shape.

  • Patent number: 8404189
    Abstract: A gas mixer is disclosed which includes a vessel (10) (e.g., pipe) containing a stream (12) of a first hydrocarbon-containing gas. The mixer includes a hollow pipe (14) located internal to the vessel containing a stream of a second gas, e.g., an oxygen-containing gas stream such as a stream of pure oxygen gas or air enriched with oxygen. The internal pipe further includes a mixer tip (30) at the peripheral end thereof. The mixer tip includes a body having an internal passage for conducting the second gas out of the pipe and an opening introducing the second gas stream into the first gas stream in a radial plane at an acute angle relative to the longitudinal axis of the pipe. The pipe further includes a deflector (20) on its external surface in longitudinal alignment with the opening of the mixer tip. The deflector serves to deflect any entrained particles within the first gas stream away from the mixing zone where the two streams mix, minimizing the risk of ignition of the hydrocarbon-containing gas.
