In the case of a rotor (109) for a device for mixing powder and liquid, which device has a stator which interacts with the rotor (109), at least some shear blades (124) are of wedge-shaped form and are inclined with one face side (233) in a flow direction (239). This has the result, in the case of an effective diversion at side walls (227) situated at the front in a flow direction (239), of an intense shear action at the face sides (233) and of a relatively low risk of formation of deposits and adherent accumulations on the side walls (230) situated at the rear in the flow direction (239).

An object of the present invention is to develop a mechanism capable of more effectively performing processing such as emulsification, dispersion, dissolution, atomization, mixing, or stirring on a processing object with fluidity using an atomization device including a rotor-stator type mixer while an inside of a processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state, and occurrence of a negative pressure state on a center side (inner diameter side) of a rotor is actively suppressed or prevented.

An atomization device comprises a rotor-stator type mixer in a processing tank. The atomization device performs processing such as emulsification, dispersion, atomization, mixing, or stirring on a processing object with fluidity using the rotor-stator type mixer while an inside of the processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state. The atomization device has a mechanism in which the rotating rotor makes the processing object flow at a predetermined pressure or higher.

The object of the present invention is to provide a method of producing organic pigment microparticles which can surely suppress growth and/or aggregation of particles. The present invention provides a method of producing organic pigment microparticles, comprising the following steps: Step 1 of precipitating organic pigment microparticles by mixing an organic pigment raw material liquid in which an organic pigment raw material is mixed with a solvent, and a precipitation solvent for precipitating the organic pigment microparticles from the organic pigment raw material liquid in a thin film fluid formed by introducing the organic pigment raw material liquid and the precipitation solvent in the space between at least two processing surfaces which are disposed so as to face each other, being capable of approaching to and separating from each other, at least one of which rotates relatively to the other; and Step 2 of coating at least a part of the organic pigment microparticles with an oxide coating; wherein the oxide coating is optically colorless and transparent, and Step 1 and Step 2 are performed out continuously in the thin film fluid, or Step 2 is completed at a predetermined time after Step 1 until the organic pigment microparticles grow and/or aggregate.

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.

In the case of a rotor (109) for a device for mixing powder and liquid, a number of connecting arms (203) are formed, as a connecting structure, between an outer blade carrier plate (215), which is equipped with outer blades (127), and a shaft receptacle (117), between which connecting arms there are situated liquid outlet regions (206). This has the result, owing to a relatively high throughput with a shear action which is still sufficient, of a relatively high mixing rate and of a relatively low tendency for powder to agglutinate.

A device (1) for mixing which comprises a housing (2) with at least one inlet (3). A first process region (4) mixes the supplied substances which are introduced via the inlet (3) while a second process region (5) discharges the mixture via an outlet (6). A first gap-forming element (7), preferably a rotor, is assigned to the first process region (4) and comprises openings (8), and a second gap-forming element (9), preferably a stator, is assigned to the second process region (5) and corresponds with the first gap-forming element (7), wherein the second gap-forming element (9) comprises openings (10). At least one of the gap-forming elements (7, 9) is rotatable relative to the other gap-forming element (7, 9). The openings (8, 10) of the first and second gap-forming elements (7, 9) are arranged such that a mixture passes through the openings from the first into the second process region.

A fluid treatment device with a new configuration is provided. The fluid treatment device is provided with an upstream treatment unit defined by treatment surfaces that rotate relative to each other, and a downstream treatment unit arranged downstream of the upstream treatment unit. The upstream treatment unit is configured such that, by passing the fluid to be treated into an upstream treatment space defined by the treatment surfaces, the fluid to be treated is subjected to upstream treatment. The downstream treatment unit is provided with a downstream treatment space which performs the function of retaining and mixing the fluid to be treated by means of a labyrinth seal. An upstream outlet of the fluid to be treated from the upstream treatment unit opens into the downstream treatment space, and the downstream treatment space is configured to use the labyrinth seal to perform the function of controlling retention time. The downstream treatment space is provided with narrow seal spaces, and retention spaces arranged upstream of the seal spaces and wider than the seal spaces, and the upstream outlet opens to a retention space.

This disclosure provides a high solids biomass slurry that is readily pumpable and transportable to downstream processing units, such as chemical and/or biochemical processing units. The slurry is amenable to saccharification efficiencies of >70 % in processing times of <36 hours. Also provided are devices for processing materials, such as the high solids biomass slurry.

A discharge gate is provided for delivering a mixed slurry from a gypsum slurry mixer, and includes a first extractor port configured for generating a first density slurry for a first gypsum layer, and a second extractor port configured for generating a second density slurry for a second gypsum layer. A channel is defined by a front panel and a side panel of the discharge gate for delivering the first and second density slurries from the slurry mixer. The first extractor port extends semi-tangentially from the front panel of the discharge gate, and is connected in fluid communication with the front panel via the channel and a first slurry passageway disposed within the first extractor port for delivering the first density slurry.
