Disclosed herein are powder mixing apparatuses and methods that utilize the deagglomerizing and mixing effects of an air flow that impacts a flowing powder. The resulting powder can have smaller particle sizes and/or exhibit a more homogenous mixture than the premixed powder.

Apparatus for mixing a fluid mixture suitable for creating microbubbles, the apparatus comprising an elongated housing extending in a longitudinal direction from a fluid inlet end to a fluid outlet end wherein the elongated housing tapers from the fluid outlet end towards the fluid inlet end along the longitudinal direction such that a cross-sectional area of an interior of the housing increases along the longitudinal direction between the fluid inlet end and the fluid outlet end, and one or more baffle plates located within the interior of the housing, each of the one or more baffle plates shaped to disrupt a flow of fluid from the fluid inlet end to the fluid outlet end.

An apparatus (100) for mixing a liquid (160) containing particulates (106, 108) comprising: a vessel (102) for containing the liquid (160) with a sidewall (120) and bottom (124); an impeller (300) rotates about a substantially vertical axis (X-X), the impeller submerging below the liquid surface (162) by a distance approximately one-tenth to one-half of the liquid (129) height; at least two spaced apart blades (310) extending radially outwardly of the vertical axis, the blades including back-swept blades pitched substantially parallel to the vertical axis, at least 50% of the length of each blade comprising an angled section (312) extending through a chord angle of 20 to 60 degrees to produce: an inner, upward flow region (164) along said vertical axis, a transition flow region (166) around the impeller in which liquid moves radially outwardly toward the vessel sidewall, and an outer, downward flow region (168) along the sidewall.

An analysis unit formed by an analysis body housing an analysis chamber and having a sample inlet and a supply channel configured to fluidically connect the sample inlet to the analysis chamber. Dried assay reagents are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilized mass formed by excipients and by assay-specific reagents.

A method for devatting the grape harvest and a device for devatting a grape harvest via the pressurized injection of air or other gases in a controlled manner into self-emptying wine making vats or similar, for the purpose of emptying the grape harvest once the maceration thereof has been completed, after the homogenization of the mixture, transferring the liquid portion to another tank and the crushed grape pulp to the press, thereby obtaining a solid phase (pomace) as a waste product which can be used to produce associated products.

The invention relates to a mixing device for mixing a fluid in a container, in particular of a fluid system, comprising a fluid supply and at least one outlet arm with an outlet opening, the fluid supply being connected to the at least one outlet arm in a fluid-communicating fashion. According to the invention, the outlet opening, for an outlet of the fluid, is oriented towards an outlet direction in order to set the fluid in the container rotating at least in sections thereof.

A method for separating a vapor from a carrier gas is disclosed. An air-sparged hydrocyclone is provided with a porous sparger covered by an outer gas plenum. A cryogenic liquid is provided to the tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the cyclone. The carrier gas is injected into the air-sparged hydrocyclone through the porous sparger. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted gas is drawn through a vortex finder while the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

Disclosed is a device for contactlessly mixing fluid present on the upper surface of the slide, where the device comprises a first nozzle array and a second nozzle array, the first nozzle array adapted to impart a bulk fluid flow to the fluid present on the upper surface of the slide, and the second nozzle array adapted to impart at least a first regional fluid flow to at least a portion of the fluid present on the upper surface of the slide.

In one embodiment, hydrodynamic cavitation lyses influent bacteria, releasing intracellular enzymes, and creates CaCO.sub.3 seed crystals that are discharged at the base of the water column. Bottom-dwelling upflow anaerobic sludge blanket (UASB)-like granules grow in a dense, viscous N, P & Ca++ rich fluid (hydrolytic brine). The brine hydrolyzes ancient sludge and fresh solids into simple liquids. The granules convert hydrolyzed liquids into gas. New CaCO.sub.3 seeds grow at the produced gas/supernatant interface and propagate across the entire lagoon. Once the sludge inventory is digested, there is an excess of granules that modulate their gross productivity in response to substrate load, pH, and temperature. In one specific example, the treated lagoon has no odor, is free of gelled sludge and effluent
