the present invention relates to a magnetic mixer to which a disposable resin liquid pouch is applied instead of a metal tank, for accommodating and mixing liquids therein, to minimize cross-contamination of liquids to be mixed due to an unwashed residue, increase a magnetic coupling force between rotors for driving an impeller inside the liquid pouch and an impeller outside the liquid pouch by a magnetic coupling method, and prevent separation of the impeller in liquids to be mixed, and a magnetic mixing system.

Devices for carbonating drinking water are disclosed. The devices include a container that is configured to hold a volume of carbonated drinking water; a CO.sub.2 gas supply line that is configured to deliver CO.sub.2 gas to the volume of carbonated drinking water within the container; and a variable speed electric motor located outside of and adjacent to an external surface of the container. In addition, the devices include a turbine type impeller that is magnetically coupled to and driven by the variable speed electric motor. The turbine type impeller is configured to rotate at variable speeds and spray carbonated drinking water transferred from a bottom portion of the container into an air space located above the volume of carbonated drinking water and the top internal surface of the container.

One embodiment provides a quick-connect and rotation system for impeller coupling including: an impeller comprising: a mixer end; and a first attachment end; the first attachment end comprising a first member that is diametrically magnetized; and an motor comprising: a rotational shaft with a second attachment end comprising a second member that is diametrically magnetized; wherein the first attachment end and the second attachment end are complementary to each other; and wherein the motor imparts rotational torque, via a magnetic field between the first member and the second member, on the first attachment end when the first attachment end and the second attachment end are connected.

Disclosed is a cold brew coffee maker and related methods of making cold brew coffee. The cold brew coffee maker can include a rotation assembly, a brew chamber, and a strainer/stirrer assembly. The strainer/stirrer assembly is adapted to be insertable into the brew chamber. The strainer/stirrer assembly having a first and second impeller that are located at a bottom portion of the strainer/stirrer assembly, the first impeller being located externally to the strainer/stirrer assembly and the second impeller located within a chamber formed by the strainer/stirrer assembly. The brew chamber portion of the cold brew coffee maker being filled partially with water, the strainer/stirrer assembly placed into the brew chamber and the brew chamber placed atop the rotation assembly. Ground coffee is added to the chamber located within the strainer/stirrer assembly and the rotation assembly is energized such that the first and second impellers cause the ground coffee and water to be mixed until a desired amount of coffee flavor is imparted upon the water by the ground coffee.

The present invention relates to an apparatus (100) for producing a driving force for stirring samples, in particular samples for laboratory operations such as, for example, liquids, liquids with solid samples contained therein or solid samples, said apparatus comprising a sample holder (200) for receiving at least one sample vessel (220) for samples and a bar element (300), which extends along a longitudinal axis (LA) and which is connected to the sample holder (200), wherein the bar element (300) comprises a coupling portion (310) for detachably coupling the bar element (300) to an operating unit (800), a fastening portion (320) for fastening the sample holder (200) to the bar element (300) and for positioning the sample holder (200) along the longitudinal axis (LA) in defined fashion, and a magnetic stirring portion (330), wherein the bar element (300) is embodied in such a way that a magnetic field that rotates relative to the sample holder (200) about the longitudinal axis (LA) can be produced by means of the magnetic stirring portion (330). The invention further relates to system (700) comprising an operating unit (800) and the apparatus (100) according to the invention, which are detachably coupled by way of the coupling portion (310). The invention further relates to a process for stirring samples in sample vessels by means of the system (700).

Heating/stirring cooker includes: main body; container that is disposed inside main body and accommodates an object to be cooked; stirring body that is disposed inside container so as to be detachable from container, stirring body having blade for stirring the object to be cooked in container and magnet disposed at a position facing an inner bottom part of container in a state in which stirring body is disposed inside container; magnetic field generator that is disposed inside main body and generates a rotating magnetic field so that a rotational force of the rotating magnetic field acts on magnet; and controller that is disposed inside main body and controls magnetic field generator. Controller is configured to control magnetic field generator so that a direction of rotation of the rotating magnetic field is switched between a forward rotation direction and a reverse rotation direction that is reverse to the forward rotation direction, and that number M of rotations in the reverse rotation direction is less than number N of rotations in the forward rotation direction.
