A fluid-driven stirring apparatus includes a fluid introduction passageway, a fluid chamber connectable to the fluid introduction passageway, a container for accommodating liquid to be stirred, and a stirring assembly. The stirring assembly includes a driving impeller arranged in the fluid chamber, a stirring shaft fixedly connected with the driving impeller and extending through the fluid chamber into the container, and a stirring member arranged on the stirring shaft and adjacent to the bottom of the container. Thus, the fluid drives the driving impeller to rotate the stirring shaft, so that the stirring member can stir the liquid in the container.

A mixing system includes a container having an encircling sidewall bounding a chamber and extending between an upper end and an opposing lower end; a support plate disposed within the chamber and secured to the encircling sidewall; an inner wall secured to the support plate and projecting within the chamber toward the upper end, an open space being formed between the inner wall and the encircling sidewall; and a first aperture extending through the encircling sidewall so as to communicate with the open space. A mixing assembly is positioned within the container and is supported on the support plate, the mixing assembly including a pliable enclosure and a mixing device.

The present invention is directed to a fluid mixing system. In an embodiment, the fluid mixing system includes a first vessel; a second vessel disposed within the first vessel; a mixer disposed outside of the first vessel in fluid communication with the second vessel; and a media introduction port disposed outside of the first vessel in fluid communication with the mixer.

A system for receiving a single-use vessel containing a mixing device has a support structure adapted to receive the single-use vessel and a drive-unit adapted to power, to control, or to power and control a mixing of contents of the single-use vessel when the single-use vessel is arranged in the support structure. The support structure and the drive-unit are provided as separate components that may be arranged both in an operating position, where the drive-unit is connectable to the mixing device of the single-use bag in the support structure, and in a separated position, where the drive-unit is separated from the support structure. The drive-unit comprises a tag reader that, in the operating position, is arranged to read a vessel tag of the single-use vessel arranged in the support structure.

A mixing system includes a container having a support plate and a mixing assembly supported on the support plate. The mixing assembly includes a pliable enclosure containing a fluid and a mixing device. A portion of the mixing device extends from the pliable enclosure and is adapted to be detachably coupled to a drive mechanism. A first plate is detachably secured to the rigid container. The pliable enclosure is disposed between the first plate and the support plate. A mixing arrangement includes a docking station having a drive cradle and a drive mechanism. The mixing system is removably positioned within the drive cradle so that the drive mechanism is removably coupled to the mixing device.

A magnetic spinner device using an impeller system to disperse heat and stir contents there-above is disclosed herein. A motor turning the impeller is offset from a center line extending vertically through the device. The impeller, however, is centered with fan blades pushing air downwards as heat rises from a heat source placed there-below, such as between legs which support the impeller and bowl of the device, the bowl being used to hold a flask and/or substances to be heated. In this manner, the electric parts (the motor) and spared the brunt of the heat by being off-center while the heat rises upwards. The simplification of parts leaves less points of potential failure compared to the prior art as does the movement of electric parts away from being above a heat source.

A stand mixer 10 comprises a head unit 50 having a lower surface presenting, in operation, a downwardly-facing drive outlet for driving in rotation at least one tool suspended therefrom. The head unit is supported with the downwardly-facing drive outlet above a receiving location 30 for a mixing bowl 40. Driving means, including an electric motor 70 and associated transmission means for conveying rotary drive to the drive outlet, are provided. The mixer further comprises first 80 and second 90 coaxial driving outlets presented on an upper surface 52 of the head unit 50; the coaxial outlets 80, 90 run at different speeds and are driven from the motor 70 by means of an epicyclic gearbox 100. The motor 70 is housed in the support means 60 with its drive shaft 72 in substantial alignment with the coaxial drive outlets 80, 90.
