An apparatus for producing nano-bubbles in a volume of liquid is described. The apparatus includes a motor having a rotatable shaft, an axially rotatable permeable member couplable to a gas inlet, and a rotatable tube support coupled to the rotatable shaft of the motor and having an inner cavity that houses the axially rotatable permeable member. When rotated, the axially rotatable permeable member is rotated so that the surface velocity of the rotatable permeable member simulates axial turbulent flow above the turbulent threshold in the liquid that allows the liquid to shear gas from the outer surface of the axially rotatable permeable member, thereby forming nano-bubbles in the liquid.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

A vortex generator apparatus including a fluid intake duct, a fluid tank including: a first fluid inlet port, a second fluid inlet port, and a fluid outlet port. A turbine is provided outside of the fluid tank in fluid communication with the fluid outlet port.

A liquor quality optimization device includes a main body defining a receiving chamber having an inlet portion and an outlet portion; an adaptor head coupled to the inlet portion of the main body for attachment to a liquor container, having a fluid passage in communication with the receiving chamber of the main body and an air passage in communication between the fluid passage and an exterior of the adaptor head; and a liquor molecular refinement structure disposed within the receiving chamber in the main body, having properties to cut and refine macromolecules in liquor into small molecules, thereby accelerating conversion of ingredients in the liquor which affects the taste, and decanting new brewed liquor as aged liquor in taste in addition to filtering sediments in liquor to enhance the taste of liquor.

A method for sterilizing by X-rays an assembly containing a single-use device intended to receive a biopharmaceutical fluid, comprising: placing a plurality of dosimeters, repeatedly passing the assembly in front of the X-ray radiation window, according to a first face then according to a second face of the assembly, at several irradiation power-time pairs (PTi), followed by mapping the radiation dose; and determining an optimum power-time pair (PTopt) for which the mapping reveals that all dosimeters have recorded a radiation dose above a minimum sterility dose (Dmin), and for which the dosimeter associated with a fragile element of the single-use device records a radiation dose below a maximum dose (Dmax) defined as being the dose from which the X-ray irradiation deteriorates the fragile element.

A decant device includes a tubular body being hollowed and having an upper end and a lower end being open. The lower end is capable of combining with a mouth of a cup. A dispenser is assembled in the tubular body. The dispenser has a plate body laterally connected to an inner wall of the tubular body. The plate body has a center portion and the plate body has a curved surface downwardly protruding from a bottom of the plate body and a recessed surface concaved from a top of the plate body. The plate body has a plurality of fan-shaped through holes surrounding the center portion, so as to form the plate body as turbine-shaped.

A wine decanter includes a housing and a variation magnetic field generator, where the variation magnetic field generator is configured to generate a variation magnetic field, and the variation magnetic field generator generates the variation magnetic field, so that a movement component that can sense a magnetic field moves in wine to make the wine move, thereby increasing contact between the wine and air. The decanting device includes a wine container, a movement component, and the decanter according to any one of the foregoing, where the movement component is placed inside the wine container, the decanter is connected to the movement component by using a magnetic field, and the decanter generates a variation magnetic field to drive the movement component to perform decanting. The structure of the decanter is simplified, thereby facilitating miniaturization, and making it convenient to carry the decanter, and also reducing noises.
