Abstract:
The present invention is a method and apparatus for mixing viscous fluids. The mixing apparatus comprises a cage located on or along a shaft. The cage comprises a support with top and bottom sides. A number of vanes extend from one or both sides of the support. In one embodiment, the vanes are generally located near an outer edge of the support. The method comprises rotating the mixing apparatus in a container of fluid.
Abstract:
A fluid handling device to assist in the mixing or separation of two or more fluids utilizing a stack of two types of alternating plates. A first plate has an aperture; a second plate has peripheral spaces around which the fluids may flow. Both types of plates are provided with a plurality of projections that serve to space the plates apart and to provide additional turbulence to the fluids as they flow around the projections. The fluids are forced to proceed back and forth through the alternating plates. The plates may be designed to fit within a housing of circular or polygonal cross-section. The projections may be tapered or non-tapered. The projections may be circular or polygonal in cross-section. Further the heights of the projections may vary to adjust the separation between adjacent pairs of plates to obtain the appropriate degree of turbulence for optimum mixing or separation of the fluids. Fluids may be introduced into the housing containing the stack of plates at various points as required by the particular fluids being handled.
Abstract:
Continuous mixing apparatus provide rapid production of a mixture of high uniformity, low viscosity, low density, high stability after mixing, without an increase in amounts of subsequently supplied liquids. Continuous production of liquid or liquid containing mixtures consists of (i) continuously loading the apparatus casing with materials of different types which are flowable such as different liquids or a powder and a liquid, (ii) mixing the components between independently rotating upper and lower bladed disk turbine impellers to form a coarse mixture, and (iii) mixing the coarse mixture with an additional portion of a liquid being continuously supplied to the casing. The apparatus includes upper and lower bladed disk turbine impellers disposed in a mixing chamber within a casing. The impellers are capable of being rotated independently at different rotational speeds. A plurality of blades are attached to the impellers. Upper and lower ring shaped baffles extend from the inner wall of the casing. A material loading opening is provided in the upper part of the casing and a liquid supply pipe extends through a side wall of the casing. A discharge opening in the bottom of the mixing chamber unloads the mixture.
Abstract:
The present invention is a frozen drink machine and a method for making frozen drinks from a frozen substance which has been frozen into a block. According to the method of the present invention, a block of frozen substance is held in a vessel while a rotatable blade having features for grinding the frozen substance, and if desirable, for aerating the ground frozen substance, acts on the block, grinding the frozen substance while a heated liquid is simultaneously introduced into the vessel. An apparatus according to the present invention supports a cup containing the frozen substance, and includes a rotatable blade which is lowered into the cup and means for pumping a heated liquid into the cup.
Abstract:
A mixing apparatus comprising a central disc driven by a rotating shaft. A number of mixing plates are stacked above and/or below the central disc. The mixing plates are spaced from and parallel to the central disc. Each plate has a central aperture and the diameter of the central aperture increases progressively away from the central disc to define a space coaxial with the rotating shaft. In operation, fluid is drawn into the space and directed out through the space between the plates. When placed near the surface of a fluid, air is drawn in and the fluid is aerated as well as mixed.
Abstract:
An impeller and shield for a mixing apparatus. A mixing member has upper and lower opposite faces and one or more apertures therethrough. Each of the apertures has an upper periphery defined by an edge of the lower face and a lower periphery defined by an edge of the upper face. The mixing member is preferably an otherwise substantially planar disc having a hole through the center for receiving a motor driven shaft. Preferably, a separate shield member having upper and lower opposite surfaces and an aperture therethrough for receiving the shaft of the motor driven impeller is provided. The impeller and shield are used in combination to minimize the escape of particulate matter into the surrounding air during a mixing operation.
Abstract:
A porous paste, especially a plaster paste or slurry for producing sandwich-type plasterboard, is made in a disk-shaped mixer having a rotor rotatable in a mixing chamber by introducing compressed air or other pressurizable gas through a wall or bottom segment directly into the chamber so that the incoming pressurized gas meets the mixture with a shearing action along the wall or bottom.
Abstract:
A fully automatic electronic milkshake mixer (10, FIG. 1) in which an operator sets scoop dial control (34, FIG. 1), based upon the number of scoops of ice-cream or related products placed in mixer cup. The mixer cup (28, FIG. 2) rotates automatically by motorized lower drive wheels (48, FIG. 1), and a top cup rim container guide/wheel assembly (54, FIG. 1) engages mixer cup upper lip (56, FIG. 2). Different sized mixer cups rotate perfectly, for faster, more complete mixing. The mixer automatically shifts from low to high speed (anti-splash feature), and turns off automatically when milkshake is done. A “ready” light (42, FIG. 1) illuminates, and a chime (68, FIG. 3) sounds—volume control and on/off being adjustable. “Manual” momentary pushbutton (32, FIG. 1) allows manual control of mixing speed and time, if desired, while cup rotates. For next milkshake, electronic mixer returns to fully automatic mode.

Abstract:
A continous mixing apparatus has an upper rotary disk and a lower rotary disk able to rotate independently of one another. A plurality of scrapers are attached to the upper and lower sides of the upper and lower rotary disks. Scrapers on the lower side of the lower rotary disk have a notch enabling the scrapers to pass over a lower ring plate in the mixer. Material to be mixed is supplied to an upper portion of the mixer, and the product is discharged from a lower portion of the mixer. The device is constructed to enable any subsequently replenished liquids to not rise to the top of the mixing apparatus. The device produces a mixture that is uniform, highly stable, and that has a small particle size or a low viscosity which can be manufactured quickly.
