A progressive shear emulsifier can include an outer body and an inner body. The outer body can have a central opening therethrough, an inlet, an outlet, and an inner surface along the central opening defining a first three-dimensional contour. The inner body can be positioned within the central opening and configured to rotate with respect to the outer body about an axis of rotation along the central opening. The inner body can have an outer surface defining a second three-dimensional contour that correlates to the first three-dimensional contour to form a material passage between the outer body and inner body. Rotation of the inner body within the outer body can create progressive amounts of shear across materials passing through the material passage, which can result in emulsified material. Conic transitions can create turbulent regions that mix the materials passing therethrough. Collective geometry can create conveyance and/or pumping of materials, which can be methylcellulose and free water.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

An apparatus for mixing a liquid or pasty product. The apparatus comprises a first housing part (11) and a second housing part (12) assembled together. The assembly of the first housing part (11) and the second housing (12) part forms•—a housing inner space (17) between an inlet (4) and an outlet (5), •—a cooling jacket (7) for circulation of a coolant fluid around the housing inner space (17), and•—a buffer jacket (9) for circulation of a clean fluid, the buffer jacket (9) being formed between the cooling jacket (7) and the housing inner space (17). The buffer jacket protects the mixed product from contamination by the coolant fluid. It also facilitates detection of leakage between the housing inner space and the buffer jacket. The invention also relates to a corresponding method.

A method of manufacturing a coffee grounds powder includes: an inputting process in which coffee grounds are input into a mixing portion of a caffeine reduction apparatus; a water inputting process in which an inlet and outlet pipe is opened and water is filled inside the main housing such that the coffee grounds input into the mixing portion are submerged; an ultraviolet ray emitting process in which ultraviolet rays are emitted to the water and an inside of the mixing portion; an elution water discharging process in which an elution water in which caffeine is decomposed is discharged to an outside from the main housing; a drying process in which the coffee grounds that remain in the mixing portion are dried by rotating the mixing portion; and a mixing process in which the coffee grounds in which drying is finished are mixed with a viscous additive.

A rotor-stator cooling system addresses the problem of heat generation and viscosity in feedstock mixers by utilizing a cooling dome which receives recirculating cooling water. The dome is attached above a rotor-stator mixer assembly having rotor and stator elements. Cooling water provides for temperature control to feedstock being drawn into the dome, as well as the feedstock circulating within the mixing tank containing the balance of the feedstock outside the dome. The rotor-stator assembly is cooled as well. In order to increase the feedstock viscosity range in the dome, an auger within a tubular member is added to the drive shaft above the rotor-stator assembly. This enables the velocity of slow-moving feedstock to increase, forcing it into the rotor-stator assembly located below. The feedstock is then further accelerated by the rotor element and forced through the stator element.

A cavitation mixing apparatus is provided for performing separations from solid material using subcritical liquid CO.sub.2. A cavitation inducing device inside a cavitation mixing vessel is held in place with a cavitation mixer mount comprising at least one fluid channel for equalizing gaseous pressure of CO.sub.2 around the cavitation inducing device. Also described is method of separating oils from a crude plant oil mixture by injecting crude plant oil into a pressurized mixing vessel comprising liquid carbon dioxide and mixing the crude oil with the liquid carbon dioxide under pressure using powered induced cavitation, the cavitation mixing vessel comprising an encapsulated cavitation inducing device.

A device for preparing frozen food product from a liquid mixture includes: a cup holder for a cup for preparing the frozen food product, a cooling unit for cooling the cavity, a stirring unit for stirring liquid mixture in the cup with a stirring element driven with a motor, a torque sensor for measuring torque applied by the motor, and a control unit configured for: starting an operational phase of the device, monitoring in a first period before a first time the torque of the motor, determining a linear increase of the torque in the first period, monitoring, after the first time, the torque of the motor, and if with respect to the linear increase of the torque in the first period an increase above a threshold occurs in the monitored torque, then initiating an ice cream termination phase, otherwise a sorbet termination phase.

A conveyance portion, a barrier portion, and a path are provided at places of a screw main body in which a kneading portion is provided. In at least one of the places, the path is provided inside the screw main body, and includes an entrance and an exit. The entrance is opened to urge the raw materials having the conveyance limited by the barrier portion to increase pressure on the raw materials, to flow in the entrance. The raw materials flowing from the entrance flow through the path in the same direction as a conveyance direction of the conveyance portion.

At a part of the screw main body at which the kneading portion is provided, conveyance portions, a barrier portion and a path are provided at a plurality of places. At least one of the places, the path is provided inside the screw main body, and includes an entrance and an exit. The entrance is opened in such a manner that the raw material whose pressure is enhanced by being restricted in conveyance by the barrier portion flows into the entrance. The path is formed in such a manner that the raw material flowing into the path from the entrance flows toward the exit in a direction opposite to the direction of conveyance.

The present disclosure relates to a system, generator and method for generating nanobubbles or nanodroplets and treating a multi-component mixture, and in particular for treating biogas and wastewater. The method comprises using nanobubbles of a gas component, and wastewater, to form hydrates in a treatment vessel; removing residual dirt from the treatment vessel and melting the hydrates to facilitate release of clean water.
