A mixing apparatus for mixing particles in a liquid and its use are disclosed. The mixing apparatus comprises a tank having a bottom and a substantially vertical side wall, an agitation means comprising a rotation shaft located vertically and centrally in the tank, and an impeller arranged at a height above the bottom at the end of the rotation shaft and the impeller being a downward pumping axial or mixed flow impeller. The bottom is equipped with a corrugated formation comprising alternate consecutive ridges and valleys, the ridges and valleys extending radially in relation to a center of the bottom, whereby the valleys concentrate and channel the mixing power near to the bottom to direct the flow of the liquid and to increase the velocity of the flow near to the bottom.

A wine-decanting cup structure includes a bottom wall, an annular wall, and a plurality of protruding ribs. The bottom wall, the annular wall, and the protruding ribs are made of polyethylene terephthalate. A bottom end of the annular wall is connected to the bottom wall to enclose a containing room for receiving wine. An outer diameter of the annular wall gradually increases and then gradually decreases from the bottom end of the annular wall to a top end of the annular wall. The protruding ribs are integrally formed on an inner periphery of the annular wall and spaced apart from each other. Each of the protruding ribs extends in a longitudinal direction and is bent toward a same direction.

The mixing or dispersing device and assembly equipped with such a device are proposed for optimizing the processing of mixed or dispersed substances, in particular tablets and/or capsules for medicinal drugs. The mixing or dispersing device includes in a mixing chamber, a motor-driven rotor having at least one cutting projection that has at least one cutting edge. A flow-disturbing element is further provided on an inner circumferential wall of the mixing chamber that surrounds the axis of rotation. Furthermore, a deflection surface is provided between the inner circumferential wall and a bottom of the mixing chamber. The at least one flow-disturbing element is spaced from the bottom of the mixing chamber, from the at least one cutting projection and from the circular path on which the at least one cutting projection is movable about the axis of rotation.

A disposable material processing apparatus, useable as a bioreactor or fermenter, includes a hollow tank (101) and a mixing paddle (110) disposed within the interior of the tank and adapted to mix contents therein. The paddle may be isolated within a flexible sleeve (140). Various functional elements, such as a sparger, sensor, material extraction conduit, material addition conduit, and/or heat exchange element may be provided, and optionally arranged to travel with the paddle within the tank interior. Baffles may protrude into a mixing tank to enhance mixing. A tank and/or sleeve may comprise polymeric film materials.

A method for controlling pressure in a blending apparatus includes sealingly coupling a blade platform to a rim of a vessel including foodstuffs to form a blending chamber. The blade platform includes a blade assembly. The method includes injecting fluid via an opening defined within the blade platform into the blending chamber while the blade platform is sealingly coupled to the vessel. The injection of fluid causes a change in pressure in the blending chamber. The method includes rotating blades of the blade assembly to process the foodstuffs in the blending chamber. The method includes introducing air into the blending chamber to decrease a difference between the pressure within the blending chamber and a pressure external to the blending chamber. The method includes decoupling the blade platform from the rim.

A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes, for example, a mixer, a foam injector, and a canister for mixing and moving a slurry mixture of foam and gypsum slurry. Also included in the system is an apparatus having a funnel body constructed and arranged to further mix the slurry mixture. The funnel body includes a number of baffles projecting from its inner wall towards a center and that are spaced around the inner wall. The baffles induce turbulence into the slurry mixture as the slurry mixture moves towards its outlet, thus further mixing the mixture and reducing the flow rate of the slurry mixture before its exits from the outlet for depositing onto paper to form the gypsum board.

An apparatus for the recovery of gold from a gold-bearing aqueous filtrate, the process comprising the steps of: (A) Contacting the aqueous filtrate with dibutyl carbitol (DBC) in a two-stage solvent extraction process to remove the gold from the aqueous filtrate into the DBC to form a gold-loaded DBC; and (D) Contacting the gold-loaded DBC with an aqueous acid scrub of hydrochloric acid in a four-stage countercurrent scrub process to remove impurities, e.g., non-gold metal, from the DBC into the aqueous scrub solution to form an impurity-loaded aqueous scrub. Each stage of the solvent extraction circuit and the aqueous acid scrub circuit is equipped with a mixing assembly and a phase separation tank in a head-tail arrangement such that the mixing assembly of one stage is adjacent to the phase separation tank of the adjacent stage.

A reactor apparatus includes a reactor having a tubular shape, and a plurality of first cooling pipes arranged inside the reactor, for circulating a coolant. Each of the plurality of first cooling pipes has a serpentine portion that extends while repeatedly bending. The serpentine portion includes a plurality of extending portions that extend linearly or extend while curving, and a plurality of bending portions which couple ends of two adjacent extending portions, among the plurality of extending portions. At least two of the plurality of first cooling pipes have different distances from an inner wall surface of the reactor.

A solvent removing apparatus includes a container containing an emulsion comprising a first raw material of a continuous phase and a second raw material of a dispersed phase, an impeller rotating in the container to stir the emulsion, and a foam breaker spaced apart from the impeller on an upper portion of the impeller, positioned below a surface of the emulsion to be submerged in the emulsion when the emulsion is calm, and rotating to reduce foam generated during stirring of the emulsion.

The present disclosure provides a stirred tank. The stirred tank includes a tank body, a stirring shaft, a plurality of blades and baffles. The tank body is configured to hold the material to be stirred; an axis of the stirring shaft is configured to coincide with an axis of the tank body; the blades are disposed on the stirring shaft; the baffles are disposed in the tank body and arranged at a periphery of the stirring shaft, and each baffle is provided with a plurality of punched holes and has a wave-like cross section. During the agitation of the stirred tank, a large number of high-speed jets are formed after the fluid passes through the punched holes.
