A dispersing device is provided by which a dispersion with a high yield and a proper dispersing process can be carried out. The dispersing device causes a mixture of a slurry or a liquid to flow by centrifugal force toward an outer circumference between a rotor and a stator. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face a lower surface of the stator, and an assembly for supplying the mixture that stores an unprocessed mixture to be supplied to a gap between the rotor and the stator. The assembly for supplying the mixture has a body, a first member for injecting the mixture, and a second member for injecting the mixture.

A mixer for a food product is described, including a vessel, an stator arranged in the vessel, and a rotor to rotate the food product relative the stator The stator is displaceable relative the rotor by a movement along a stator guide The stator guide includes an interior cavity being enclosed by a wall extending into the vessel, and a first magnetizable material arranged inside the cavity The stator includes a second magnetizable material, wherein a magnetic field between the first and second magnetizable materials generates a force that moves the stator along the stator guide for displacement of the stator relative the rotor.

The problem addressed by the present invention is providing a fluid processing method including extraction that can extract material to be extracted continuously with high efficiency. In a thin film fluid formed between at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, a fluid processing that extracts at least one kind of material to be extracted in at least one kind of the extraction solvent that can extract that material to be extracted is carried out. In addition, the fluid containing at least one kind of material to be extracted and a fluid for extraction that contains the at least one kind of extraction solvent are mixed in the thin film fluid formed between the at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, and a fluid processing process that extracts the at least one kind of material to be extracted into the at least one kind of extraction solvent is carried out.

A mixing apparatus for producing aqueous calcined gypsum slurry includes a housing, a rotor assembly, and an actuator system. The housing defines a mixing chamber therewithin. A top lid of the housing includes a lid ring extending along a normal axis toward a bottom thereof. The rotor assembly includes a rotor disposed within the mixing chamber and a drive shaft extending along and rotatable about the normal axis. The rotor is rotatively coupled with the drive shaft and extends radially therefrom. The upper surface of the rotor and the lid ring are separated by a lid ring gap along the normal axis. The actuator system is arranged with the rotor assembly to selectively move the rotor over a range of travel along the normal axis between a lowered position and a raised position to selectively change the lid ring gap.

A cavitation device is provided for use in a method for the treatment of water by cavitation. The water to be treated passes through an annular cavitation zone which exists between two mutually opposite annular structures which rotate relative to one another and which have teeth directed substantially axially towards one another. Here, the water flows along cavitation surfaces which are provided on the face sides of the teeth of a first of the two annular structures and which are inclined in the circumferential direction such that, viewed in the relative direction of rotation of the other, second annular structure, the spacings between said teeth and said second annular structure increase.

A tank apparatus and a system for dispersing by circulating a mixture that prevents powdery additives from adhering to an inner face of a tank from scattering in the tank, from drifting on the surface of a liquid, and from agglutinating, are presented. The tank apparatus that stores a raw material that is slurry or liquid and supplies powdery additives to the raw material to mix them with the raw material comprises a tank for storing the raw material and a screw-type device for supplying powdery additives that is integral with the tank and supplies the powdery additives to the raw material in the tank, wherein a tip of a part for supplying powdery additives of the screw-type device for supplying powdery additives is inserted into the mixture in the tank.

A fluid is processed between processing surfaces capable of approaching to and separating from each other, at least one of which rotates relative to the other. A first fluid is introduced between processing surfaces, by using a micropump effect acting with a depression arranged on the processing surfaces from the center of the rotating processing surfaces. A second fluid, independent of this introduced fluid, is introduced from another fluid path that is provided with an opening leading to the processing surfaces, whereby the processing is done by mixing and stirring between the processing members.

A mixer for a food product includes a vessel, an stator arranged in the vessel, and a rotor to rotate the food product relative the stator. The stator is displaceable relative the rotor by a movement along a stator guide. The stator guide includes an interior cavity being enclosed by a wall extending into the vessel, and a first magnetizable material is arranged inside the cavity. The stator includes a second magnetizable material, wherein a magnetic field between the first and second magnetizable materials generates a force that moves the stator along the stator guide for displacement of the stator relative the rotor.

A membrane/electrode assembly of a fuel cell using a film obtained by molding a mixture in which a synthetic resin and a solvent are mixed with fullerene nanowhisker/nanofiber nanotubes supporting a catalyst or including a catalyst in fullerene crystals, wherein the fullerene nanowhisker/nanofiber nanotubes are obtained by uniformly stirring and mixing a solution containing a first solvent having fullerene dissolved therein, and a second solvent in which fullerene is less soluble than that in the first solvent, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the resultant fullerene nanowhisker/nanofiber nanotubes are heated at 300 C. to 1000 C. in a vacuum heating furnace.
