A mixing block for mixing components of a beverage prior to the mixture reaching the tap, for improving the consistency of the mixed beverage as it leaves the tap. The invention is particularly effective when one of the components tends to settle out during storage. In the mixing chamber, one stream goes straight through and the other impinges from the side, to cause enhanced mixing.

A first inlet flow can be directed along an axial direction in a hydrocyclonic flow cell. The first inlet flow can include first constituent molecules. At a same time, one or more second inlet flows can be directed along a circumferential direction of the hydrocyclonic flow cell. Each second inlet flow can include a buffer solution. The first inlet flow can be subjected to flow focusing by a surrounding primary vortex formed by the one or more second inlet flows, so as to generate a flow comprising a plurality of nanoparticles at an outlet of the hydrocyclonic flow cell. Each nanoparticle can be formed by a respective plurality of the first constituent molecules.

A mixing and dispersing apparatus includes a tank body, a stirring part, a dispersing part, and a driving part. The tank body has an accommodating cavity configured to accommodate materials. The stirring part is disposed in the accommodating cavity and configured to mix the materials in the accommodating cavity. The dispersing part is disposed in the accommodating cavity and includes a first cylinder and a second cylinder. The first cylinder has a first cavity in communication with the accommodating cavity, the second cylinder is located in the first cavity, and the second cylinder has a second cavity in communication with the accommodating cavity. The driving part is connected to the stirring part and the dispersing part. The materials mixed in the accommodating cavity flow into the second cavity and flow out after being dispersed in the dispersing part.

A bladeless mixer for mixing a liquid, includes a cylindrical or truncated cone-shaped receptacle having an axis A and a radius R, the radius R being the shortest distance between the axis A and a side wall of the receptacle, the liquid to be mixed being placed in the receptacle and having an exposed surface at a height H measured along axis A; a member for tilting the receptacle such that axis A forms a non-zero-degree angle of up to 30° relative to the vertical direction; a member for imparting a rotational movement to the receptacle along axis A at an angular speed of rotation Ω; wherein the aspect ratio H/R of the height H to the radius R and the angular speed of rotation Ω are selected such that an inherent mode of inertia of the liquid has an unstable resonance when the receptacle is tilted and rotates.

A method for preparing a dispersion of nanoparticles of a solid organic dye or pigment in a liquid carrier, the method comprising continuously mixing: at least one solution or slurry containing a reactant precursor for the solid organic dye or pigment in an organic or other solvent with the liquid carrier in a counter current mixing reactor whereby to obtain reaction of the reactant precursor and formation of the solid organic dye or pigment as a dispersion of nanoparticles in the liquid carrier and solvent mixture; optionally, removing unreacted reactant precursor and/or by-product from the dispersion when present; and optionally, concentrating the dispersion.

Embodiments of the disclosure produce a method and system for deasphalting a hydrocarbon feed. The hydrocarbon feed and a first solvent is combined using a Taylor-Couette mixer to form a mixed stream. The mixed stream and a second solvent are introduced to an extractor to produce a first deasphalted oil stream and a pitch stream. The first deasphalted oil stream is introduced to a solvent recovery unit to recover the first solvent and the second solvent via a recovered solvent stream and to produce a second deasphalted oil stream.

Agitating device (10) for a digester (1) of a biogas plant (100) having a housing (11) and a driving device (12) for rotatably driving the agitator blades (13-15). The driving device (12) comprises a drive shaft (16) and an electric drive motor (20) wherein the drive motor (20) is accommodated sealed in the housing (11). The drive motor (20) comprises an outer, hollow stator (21) and a rotary rotor (22) which is centrally accommodated therein and is configured at least partially hollow. The rotor (22) is rotatably supported at the housing (11) and comprises a coupling device (23) for non-rotatable coupling with the drive shaft (16) to drive the at least one agitator blade (13-15) by means of the drive shaft (16).

A device for generating bubbles or droplets may include a cavity comprising a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary. The opening of the tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary. The cross section of the cavity may be selected so that, in use, the average speed field in the cavity is quasi-static.

The present invention relates to compositions and methods for manufacturing an adjuvant comprising a saponin using a microfluidic device and to aspects thereof.

A fine bubble generation device in one aspect of the present disclosure is a device that generates fine bubbles in a liquid by causing the liquid to pass through a porous element having many pores. In the fine bubble generation device, a differential pressure is applied between first and second sides of the element, and, by the applied differential pressure, the liquid disposed on the first side of the element is passed through the element and is jetted toward the second side to thereby generate fine bubbles. In this fine bubble generation device, the flow speed of the liquid during passage through the element is 0.009769 [m/s] or higher. The fine bubbles can thereby be generated efficiently.
