A mixing device is configured for the continuous provision of a gelling mass for a molding machine. The mixing device includes an inlet, an outlet and a conduit section which is situated between the inlet and the outlet and into which at least one admixing conduit runs out, via which admixing conduit a substance to be admixed can be fed such that the substance to be admixed is mixed with a base mass which is fed through the inlet, in a mixing region in the conduit section. The mixing device is configured in a manner such that the spatial distance between the outlet and the mixing region in which the substance to be admixed is mixed with the base mass, can be changed. A molding machine with such a mixing device and to a method for processing a flowable and gellable mass are provided.

A multi-component fluid mixing device for mixing two or more fluids which can be used with an applicator tool, such as a spray gun. The mixing device is used with a removable cartridge that is pressure fitted into the body of the mixing device using an actuation mechanism that elevates a cartridge engagement base to create a fluid-tight seal.

A hydrodynamic cavitation generating device and a method, including: a wheel disc, being provided with a plurality of flow passages, an orifice plate is provided inside the flow passages, and a throat orifice is provided on the orifice plate; a driving mechanism, being connected to the wheel disc, and configured to drive a rotation of the wheel disc; and a water-inlet pipe, being arranged fixedly, fitting with a first side end face of the wheel disc, and may inject water into the flow passage when being aligned with the flow passage; the cavitation effect obtained by using the hydraulic cavitation generating device is better.

A method for the dynamic inline mixing of a pressurized medium containing a liquid and at least one further liquid or solid constituent in a bioprocess arrangement, the liquid being merged with the at least one further liquid or solid constituent in a predefined volume ratio at an opening point to form a resulting liquid flow, the bioprocess arrangement having a pump arrangement with a first pump, the first pump being arranged in the line of the line arrangement, the first pump being designed as a rotary pump configured for the dynamic inline mixing of the medium, the first pump having a liquid inlet, which during intended operation forms the suction side of the pump, and a liquid outlet, which during intended operation forms the pressure side of the pump, and the medium being conducted through the rotary pump for the purpose of dynamic inline mixing.

There is provided an oxygenation assembly and an aquaculture diffuser thereof. The diffuser includes a plurality of circumferentially spaced-apart gas injection ports. The diffuser includes a plurality of circumferentially spaced-apart and axially-extending passageways. Each axially-extending passageway aligns with a respective one of the gas injection ports. Each axially-extending passageway is shaped to receive a mixture of water and oxygen-containing gas therethrough. The diffuser includes a plurality of circumferentially spaced-apart and radially outwardly-extending passageways. Each radially-extending passageway is in fluid communication with a respective one of the axially-extending passageways. Each said passageway may include an intensifier or constriction between proximal and distal end portions thereof. The diffuser may include a plurality of circumferentially spaced-apart expansion chambers each positioned between and in fluid communication with a respective said axially-extending passageway and a corresponding respective said radially-extending passageway. The diffuser is shaped to induce a homogeneous ramping turbulent kinetic energy (TKE) dissipation field.
