The invention relates to an apparatus for aerating a pasty product. The apparatus comprises a housing (1) with an inlet (4) for the pasty product to be aerated and an outlet (5) for the aerated product. The apparatus comprises at least a first set of a rotor and a stator (21) and a second set of a rotor and a stator (22). The apparatus further comprises a gas injector (6) for injecting, upstream of the first set of a rotor and a stator (21), a gas into the pasty product to be aerated. The apparatus further comprises an intermediate mixing chamber (7) provided in the housing between the first and the second sets of a rotor and a stator (21, 22).

Formulations containing a carrier and microbubbles encapsulating oxygen gas, and methods for making and using the formulations are described herein. The formulations are manufactured by a process which includes high shear homogenization. The resulting microbubble suspension may be centrifuged to further concentrate the microbubbles. The resulting concentrated LOM suspension preferably has an oxygen content ranging from 50 to 99% (vol). Prior to administration to a patient, the viscosity of the LOM suspension may be reduced to the desired viscosity, preferably similar to the viscosity of the patient's blood. The resulting LOM formulation typically has an oxygen concentration ranging from 65 to 80% (vol). The microbubbles are formed from one or more lipids, preferably one or more phospholipids, most preferably DSPC, and preferably also contain one or more stabilizing agents/excipients, preferably cholesterol.

An apparatus for use in a bathtub containing water includes an outer shell, a soap holder, configured to hold a liquid soap, at least one set of blades, and a motor disposed within the outer shell and coupled to the set of blades. The motor is configured to form soap bubbles by spinning the set of blades such that the blades lift the water from the bathtub, and pass the lifted water, together with liquid soap from the soap holder, through air.

The invention relates to a milk-frothing device with a dynamic mixing unit having a stator and a rotor which can be set in rotation relative to the stator, rotor and stator being configured such that milk and air can be conducted firstly to the dynamic mixing unit, subsequently, for frothing-up in the dynamic mixing unit, can be subjected multiple times to a shearing effect by rotation of the rotor relative to the stator and finally can be discharged out of the dynamic mixing unit.

A method, system and apparatus for making oxygenated foamy beverages are described.

A system structure of an impeller for a dispersion-emulsion apparatus based on dual rotor is provided. This system includes an impeller unit in which an impeller constituted by a first rotor and a second rotor is configured in multi stages, in which the first rotor and the second rotor are driven in reverse rotational states to each other by driving motors of the respective rotors and respective target materials to be mixed sequentially pass between the multi-stage impeller units at once by a one-pass method, and as a result, a total working time for processing of dispersion-emulsion is significantly shortened, uniformity of a particle size is enhanced by micro shearing (cutting) of the respective mixed materials.

Various embodiments herein pertain to apparatus and methods that utilize the water and existing chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces, to contact, scrub, carry, and remove fouling away from equipment to restore performance. Some embodiments include mixing gas with liquid to create a supply of foam, streaming the foam into a gas turbine engine installed on an airplane, rotating the spools of the engine while streaming, and re-rotating the spools of the engine after a spool has stopped. In yet other embodiments there is a method that includes streaming the foam into an engine installed on an airplane, quantifying an improvement to a family of engines achievable by foam washing, operating a specific engine, determining that the specific engine should be washed, and scheduling a foam washing of the specific engine.

A device for loading an in particular higher-viscosity liquid, such as a silicon resin, for example, with air or another gas. The device has a pressure vessel receiving the liquid and the gas, in which pressure vessel an agitator, having a drive shaft set through the pressure vessel at least in part, is arranged. In order to enable the particularly fast and homogeneous intermixing of the liquid and gas, the drive shaft is arranged in a conveying pipe and drives a conveying organ, in particular a screw conveyor, which transports the liquid through the conveying pipe to at least one outlet, and there is an running-off surface underneath the outlet from the conveying pipe for the liquid flowing out of the outlet. Upon actuation of the agitator, the liquid is thus not only well intermixed together with the air already received therein, but at the same time conveyed through the conveying pipe to the running-off surface, on which it can discharge in a thin layer and has a particularly large exchange area with the gas as a result.

A method for aerating a pasty product and for mixing with another product is disclosed herein. In one example, the method includes passing a stream of pasty product to be aerated through an apparatus. The apparatus includes a housing, the housing including an inlet for the pasty product to be aerated an outlet for the aerated product. The apparatus further includes a gas injector for injecting a gas into the pasty product to be aerated. The apparatus further includes an intermediate mixing chamber and a secondary product introduction member. The method further includes injecting via the upstream gas injector a gas into the pasty product stream at a position upstream relative to the first set of a rotor and a stator. The method further includes injecting a secondary product via the secondary product introduction member into the intermediate mixing chamber.

The invention relates to a method and a colloidal mixer for colloidal processing of a slurry, in particular processing of construction materials, with a colloidal mixer, in which at least one liquid is introduced into a mixing trough, at the lower region of which is arranged an outlet opening with a mixing device having a mixing rotor, which is driven in rotation.

According to the invention, the at least one pulverulent solid component is introduced into the mixing trough, the at least one liquid mixed with the at least one pulverulent solid component is induced to flow by the rotatingly driven mixing rotor and is discharged from the mixing trough through the outlet opening, wherein the mixture is led back again for a certain time via a backflow line into an upper region of the mixing trough for further mixing and, after a desired mixing state has been attained, the mixture is discharged as a finished slurry from the outlet opening by means of a discharge line.

According to the invention, it is provided that air is incorporated into the at least one liquid and/or the mixture in a targeted manner in a finely dispersed form, wherein a relative density of the liquid, or of the mixture, is reduced.
