Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

A cavitation device is supplied by a disc pump with fluids for mixing. A cavitation rotor, having an array of cavities on its cylindrical surface, is fixed to a shaft for rotation by a motor. The disc pump and the cavitation device are beneficially in the same housing. At least one disc is spaced from and attached to the rotor near the inlet end of the cylindrical housing, so it will rotate with the rotor. A central hole in the (at least one) disc permits fluid to enter the space between the disc and the rotor; it is flung toward the peripheral space between the rotor and the cylindrical housing, where it is subjected to cavitation, and then passed to an outlet. The shaft may pass through one or both of the end walls of the cylindrical housing. The cavitation pump is especially useful for mixing oil field fluids.

An apparatus to generate soapsuds is described. The apparatus features a character lid, a lid attachment member, a holding member, an agitator, and a soap dispenser. The holding member includes a chamber portion sized to retain one or more soap tablets. The chamber portion has an opening, a closed end including an outlet, and lateral surfaces extending between the opening and the closed end. The agitator is rotationally coupled to the holding member and positioned under the outlet of the holding member. The soap dispenser includes a housing that encapsulates the agitator residing within a lower quadrant of the interior area of the housing. The housing includes apertures formed within the closed end to allow for soapsuds and soapy water passage through the opening and the outlet of the holding member, which causes the agitator to mix the soapy water residing within the interior area to generate soapsuds.

Polyacrylamides, guar gum (sometimes guar), xanthan gum, carboxymethylcellulose, hydroxyethylcellulose, and other water-soluble polymers are dissolved and hydrated in aqueous solutions, including especially recycled drilling, fracturing, and other oilfield fluids having significant salt contents, by passing the water-soluble polymer together with the aqueous medium to a cavitation device including an integrated disc pump. The integration of a disc pump with the cavitation device reduces the risk of gumming by applying a negative pressure at the feed point. The ability to use water-soluble polymers with the salty recycled oilfield fluids has significant environmental benefits, namely (1) fresh water is not needed, (2) disposal of the environmentally undesirable returned fluids is not needed, (3) difficultly degradable synthetic polymers may not be needed, and, in particular, (4) the enhanced ability to use guar, which, being a natural product, is biodegradable, is environmentally favored. Although the invention is most beneficial for use with salt or brackish water, its high efficiency points to beneficial use where fresh water is the only available choice for the aqueous medium. Where dry polymer is used, the invention's benefits are especially realized in terms of logistics and handling, since viscous and bulky solutions need not be prepared and stored in advance, thus also minimizing health, safety and environmental risks

An apparatus is especially suitable for high volume manufacture of a non-dairy frozen dessert. Pre-frozen blocks of ingredient mixture are masticated in a first stage of the apparatus and aerated in a second stage of the apparatus. Compressed air is injected into a masticated slurry produced by the first stage and mixed into the slurry in the second stage. A continuous process transforms the pre-frozen blocks into a masticated, aerated slurry suitable for immediate consumption, storage for later consumption, or processing into bars or other forms. This apparatus and process is suitable for some ingredient mixtures for which a scrape surface heat exchanger apparatus and process are not suitable.
