A stirring impeller, an arrangement, and a use. The impeller comprises a hub disc comprising a shaft attachment structure arranged centrally in the hub for receiving a shaft centrally and perpendicularly from an upper side of the hub disc, a plurality of upper blades arranged on the upper side of the hub disc, and a plurality of lower blades arranged on a lower side of the hub disc. At least one of said plurality of upper blades is arranged to have jet angle of 5-45, and the lower blades have a jet angle that is different than said jet angle of least one of said plurality of upper blades.

A nut paste preparation for food and beverages is formed by processing blanched, unroasted nuts into a nut based flour having a mean particle size between about 0.002 and 0.012 inches. The processing occurs without adding water and oil. The temperature during processing does not exceed 140 degrees Fahrenheit. The nut based flour is sheared without adding water and oil to form a nut paste. The temperature during shearing does not exceed 120 degrees Fahrenheit. The nut paste after shearing has a mean particle size of about 1 to about 40 microns.

A food and beverage paste preparation is formed by delivering a flour derived from nuts, seeds, grain or beans into a shear mixer. The flour may have a mean particle size between about 0.002 and 0.012 inches and a moisture content between about 4 to about 6 percent. The flour is sheared without adding water for mixing to form a food and beverage paste. The temperature during shearing does not exceed 120 degrees Fahrenheit and the food and beverage paste after shearing has a mean particle size of about 1 to about 40 microns.

There is provided a stirring device including a stirring tank including an inner peripheral wall which is circular in cross section, at least one circulating impeller and at least one dispersion blade which are located inside the stirring tank and rotatable around a vertical axis independently of each other, and a guide ring disposed radially outward near the dispersion blade. The circulating impeller is disposed along the inner peripheral wall of the stirring tank, and rotates around the vertical axis to form at least a downward flow in a stirring object existing inside the stirring tank. The dispersion blade rotates to apply a shear force to the stirring object, and is disposed at a radially inner position of the stirring tank from the circulating impeller, and at a position in contact with a flow of the stirring object, which is formed by the circulating impeller.

The present disclosure relates to a container for the production of a foamed sclerosant composition, to kits and systems including such a container, to methods for preparing a foamed sclerosant composition using such containers, and to a foamed sclerosant compositions obtainable by such methods. In an aspect, the container comprises a container body and a mixing element disposed in the container body, such that a foaming space is defined in an interior of the container body between the sidewalls and the mixing element. The mixing element may be configured to be operatively coupled with a rotating actuator without the actuator reaching the foaming space.

A method and apparatus for the treatment of water and, more particularly, to the mineralization of water in order to improve pH, hardness, turbidity, and/or alkalinity is described. More particularly, a system is provided for the treatment of water that needs additional hardness, alkalinity, and/or pH adjustment while also meeting turbidity requirements. The use of sodium hydroxide and other methods for avoiding turbidity problems can be eliminated and/or minimized.

A three-dimensional printing device with a stirring mechanism includes a vessel (1), a molding platform (2), a light source module (3) and a rotary stirring structure (4). The molding platform (2) is elevatably installed above the vessel (1); the light source module (3) is installed under the vessel (1); and the rotary stirring structure (4) includes a magnetic stirrer (41), a magnetic turntable (42) and a driver (43). The magnetic stirrer (41) is placed inside the vessel (1); the magnetic turntable (42) is installed under the vessel (1) and magnetically attracted to the magnetic stirrer (41); the driver (43) drives the magnetic turntable (42) to rotate and move, so as to drive the magnetic stirrer (41) to rotate and move with respect to the vessel (1) and improve the convenience of using the three-dimensional printing device (10).

A positive active material manufacturing method according to an exemplary embodiment of the present invention includes: a step of preparing a lithium-containing compound; a step of manufacturing a coating liquid including at least one coating element; a step of mixing the lithium-containing compound and the coating liquid to form a coating mixture of a clay or slurry state; and a step of agitating the coating mixture. Further, a manufacturing apparatus of a positive active material according to an exemplary embodiment includes a rotation container, a cover, a nozzle, and an agitation wing.

Aeration discs used in water treatment and methods of using same are disclosed. According to one or more embodiments, an aeration disc may comprise projections and depressions located on at least one of its surfaces. The aeration discs may be incorporated into aeration devices and water treatment systems.

A continuous ready mix joint or texture compound manufacturing system and a method for continuously manufacturing a ready mix joint or texture compound includes a continuous mixer having an inlet and an outlet, a pump disposed at the outlet of the continuous mixer, and a disperger having an inlet and an outlet. The continuous mixer is adapted to receive at least one dry ingredient and at least one wet ingredient at the inlet and continuously mix the at least one dry ingredient and the at least one wet ingredient to form a mixed composition. The pump is adapted to pump the mixed composition from the outlet of the continuous mixer to the inlet of the disperger. The disperger is adapted to receive the mixed composition and apply a shear force to the mixed composition to form a homogenized, disperged composition.
