A stirring wand is configured for selective engagement with a mixing device. The stirring wand comprises a substantially vertical portion having an upper end and a lower end, a first tapered surface that includes a first pitch angle proximate the upper end of the substantially vertical portion and a second pitch angle proximate the lower end of the substantially vertical portion, a substantially horizontal portion having a base and a distal tip, and a second tapered surface extending from the base to the distal tip. The second tapered surface includes a third pitch angle proximate the base and a fourth pitch angle proximate the tip.

A method is described of mixing fluid materials, including solids and gases. The materials to be mixed are introduced between two cylindrical rotors mounted in parallel on a motorized shaft. The rotors have arrays of cavities on their cylindrical surfaces and rotate within close proximity to the interior of a cylindrical shell. Passage of the fluid between the rotating rotors and the interior surface of the cylindrical shell causes cavitation, which mixes the materials. The mixture is passed to outlets on the far sides of the rotors from the inlet. Apparatus is described for extending the flow path of the materials and thus increasing exposure to the cavitation process.

The invention relates to a capsule (3) for producing a composition, particularly for dental care, comprising an enclosure (6) provided with at least two compartments (8), the number of compartments corresponding to the number of components to be mixed, and at least one wall (10) for isolating the components, said wall (10) being provided to isolate the components form each other in storage mode, and to allow fluidic communication between the compartments (8) in mixing mode, said capsule also comprising a driving rod (2), one end of which is designed in compliance with the ISO 1797 standard, for removable attachment to a hand-held part (1).

A handheld apparatus for mixing food product comprising a manual input and a drive structure comprising a drive input, wherein the manual input is operatively connected to the drive input to actuate the drive means, the drive means further comprising first and second drive outputs operatively coupled to the drive input and being arranged to simultaneously rotate the first drive output in a first direction and rotate the second drive output in a second direction and rotate both drive outputs in the second direction about the central axis of the apparatus, such that the number of revolutions completed by the first drive output is less than the number of revolutions completed by the second drive output each time the drive outputs complete a revolution about the central axis.

A method of controlling a portable appliance includes measuring an input current supplied to a motor of the portable appliance and measuring a rotational speed of a shaft of the motor. The method also includes determining a current limit based on the rotational speed of the shaft using a substantially continuous function which relates a domain of rotational speeds to a range of current limits. The method further includes reducing, when the input current exceeds the current limit, the rotational speed of the shaft incrementally along the substantially continuous function until the input current is approximately equal to the current limit.

The invention relates to a rotary shaft (23) for processing foodstuffs, wherein the rotary shaft (23) has a rotation axis and the rotary shaft comprises at least one tool (11). The at least one tool (11) extends along the rotation axis. The tool (11) further has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface, wherein the leading edge and the trailing edge are different.

A Container is disclosed with a stirrer device suitable to be installed on machines for dispensing fluid products. The container comprises a tank with a particular configuration defined by two cylinders each having a respective longitudinal axis, wherein the distance between two of the longitudinal axes is less than the diameter of a cylinder, and in which two stirrer units are comprised, coaxial to the cylinders of the tank. The stirrer units have elements that have a radial dimension a little less than the radius of the cylinders and are disposed along the substantial entirety of the longitudinal extension of shafts rotating axially, said shafts not having around them a zone not spatially affected by a stirrer element attached to said corresponding shaft.

[Object] To provide a mixing device capable of accurately mixing a solution in a multi-well plate.

[Solving Means] A mixing device 1 is configured to be attachable to a multi-well plate 30 and includes a casing 100, a plurality of stirrers 11, a plurality of motors 12 as a drive portion, and a mounting portion 16. The casing 100 includes a main surface portion 101 facing an upper surface 301 of the multi-well plate 30.

The mounting portion 16 is provided to the casing 100 and is mounted to the multi-well plate 30 to position the casing 100 on the multi-well plate 30.

A mixing vessel for a food processor operated by an electric motor, which mixing vessel has a mixing mechanism which can be connected to a rotary drive of the food processor by means of a coupling driver, wherein the mixing vessel has a cleaning device for cleaning an inner wall of the mixing vessel, in particular a floor of the vessel. The cleaning device is arranged on the mixing vessel, in particular on a vessel wall and/or the mixing mechanism, and has at least one cleaning element which is designed such that, upon actuation of the cleaning device, it sweeps over the inner wall and/or over sub-regions of the mixing mechanism and, by interacting mechanically with any deposits which may be located on the inner wall and/or the mixing mechanism, helps to remove the same. The mixing vessel can have a cleaning device which has an ultrasonic transmitter, which is arranged in a fixed position in a wall of the mixing vessel or which is arranged, in particular in a removable manner, in the interior of the mixing vessel.

An agitator includes a central shaft, a radially spaced array of vanes and a shroud encircling the central shaft so as to intersect the vanes perpendicular to the vanes' depth and along their length, thus defining an inner passageway between the shroud and the central shaft and an outer passageway between the vanes, radially extending outwardly of the shroud.
