An air-stirred tank reactor (ASTR) and methods of use thereof are described herein. The ASTR is equipped with an impeller or set of impellers that mechanically mixes a liquid culture, as well as sparges gas into the liquid medium. The impeller can further have lighting sources that can illuminate the liquid culture. Unlike conventional bioreactors, the ASTR provides superior liquid mixing, efficient gas mass transfer, and a low-shear culture environment through appropriate impeller rotational speed and sparging rate.

An agitator for an apparatus for the manufacture of three-dimensional objects. The agitator comprises at least one blade coupled to a shaft, and extending outwardly from the shaft. Cavities are defined between the at least one blade and the shaft, such that movement of the agitator within a powder repository keeps the powder in a fluidised state and prevents the powder from agglomerating.

The present invention relates to a stirring rod of hot and cold foods supplying machine and an assembled stirring unit thereof. The assembled stirring unit includes an assembled piece and a stirring blade, wherein a length direction of the assembled piece is an axial direction, a direction perpendicular to the axial direction is a radial direction, and the assembled piece has a first joining piece and a second joining piece respectively at two ends thereof in the axial direction. The stirring blade is provided on the assembled piece and extends towards the radial direction, and the stirring blade is twisted at an angle by having the radial direction as an axis. The stirring rod is formed by serially connecting multiple assembled stirring units along the axial direction.

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.

A mixing apparatus for mixing substances includes a single-use apparatus and a reusable apparatus. The single-use apparatus includes a flexible mixing tank configured to receive the at least two substances to be mixed, is plastic, and has a rotor arranged in the mixing tank. The rotor includes an impeller configured to mix the at least two substances, the impeller being magnetically contactlessly drivable and free of coils and permanent magnets. The reusable apparatus includes a support tank configured to receive the mixing tank and a stator configured to magnetically contactlessly drive the rotor about an axis of rotation in an operating state. The stator includes at least one permanent magnet configured to generate a permanent magnet flux and at least one winding configured to generate an electromagnetic flux, the permanent magnet flux and the electromagnetic flux together being capable of driving the rotor.

A powdery material mixing degree measurement device includes a discharger configured to discharge mixed powdery materials to a filler configured to fill, with the powdery materials, a vertically penetrating die bore of a compression-molding machine including a table including the die bore, a slidable lower punch including an upper end inserted to the die bore, and a slidable upper punch including a lower end inserted to the die bore, a plurality of movable portions configured to move the mixed powdery materials to the discharger, and a sensor configured to measure a mixing degree of the mixed powdery materials in the movable portions.

A continuous mixing apparatus for a powder/granular material and a viscous liquid, with a mixing cylinder, a shaft member which is on a central axis of the mixing cylinder and rotates inside the mixing cylinder, and a plurality of mixing paddles disposed on a surface of the shaft member, wherein the mixing cylinder is with a powder/granular material feed port on one end portion, a mixed material discharge port on the other end portion, and a viscous liquid injection unit between the powder/granular material feed port and the mixed material discharge port, and the plurality of mixing paddles are disposed on the shaft member so as to form a spiral around the central axis, the plurality of mixing paddles being, in at least a portion between the viscous liquid injection unit and the mixed material discharge port, attached to provide first rows having an attachment angle of 5 to 60.

A system for continuously making-down a dry powder material is provided. The system may include a liquid supply system, a material feed system, a vessel, a filter, and an agitator. The vessel may receive a continuous supply of liquid from the liquid supply system and a continuous supply of dry powder from the material feed system. The liquid and material may be discharged continuously from the vessel. A filter may sealingly extend across the outlet to filter the solution exiting the vessel. The filter may include an upstream surface in contact with the inner volume of the vessel. The agitator may be disposed within the vessel and may be configured to agitate the contents of the vessel. The agitator may include a wiping member configured to contact the upstream surface of the filter while agitating the contents.

A stirring tool for a stirrer for stirring a mixture comprises a connecting element for connecting the stirring tool to a stirring drive, drivable about a rotational axis, of the stirrer, a carrier ring, a plurality of stirring spokes disposed between the connecting element and the carrier ring, and at least one stirring boss which projects radially on the carrier ring. Two adjacent stirring spokes are arranged mutually offset in the direction of the rotational axis.
