The device including at least one production nozzle including a first duct intended to convey a first fluid that forms the first phase, a second duct, coaxially surrounding part of the first duct, able to convey a second fluid that forms the continuous phase, and an outlet. The nozzle is able to form, at the outlet, a fluid jet including the first fluid and the second fluid surrounding the first fluid. The production device additionally includes a fragmentation device for mechanically breaking up the fluid jet, positioned in the vicinity of the outlet of the nozzle, the fragmentation device including a mobile part intended to break up the fluid jet mechanically into a plurality of elements.

A disperser includes an outer member and an inner member located radially inside the outer member. A flow path is formed between the outer member and the inner member, through which fluid flows from one side to the other side in the axial direction. The flow path includes a first region that extends spirally from the one side to the other side and a second region that extends continuously from the first region to the other side. The second region is defined by the tapered inner circumferential surface of the outer member and the tapered outer circumferential surface of the inner member. The tapered inner circumferential surface and the tapered outer circumferential surface are formed such that the angle of one with respect to the other in the axial cross section changes in the middle of the second region, and the second region of the flow path has portions each having a different clearance distance.

A disperser includes an outer member having a tapered inner circumferential surface, an inner member having a tapered outer circumferential surface that faces the tapered inner circumferential surface, and a clearance adjustment part that allows a clearance distance between the tapered inner circumferential surface and the tapered outer circumferential surface to be adjusted by moving the outer member and the inner member relative to each other. A flow path is formed between the inner circumferential surface of the outer member and the outer circumferential surface of the inner member, through which fluid flows from one side to the other side. The flow path includes a dispersion region defined by the tapered inner circumferential surface and the tapered outer circumferential surface. The tapered inner circumferential surface and the tapered outer circumferential surface are formed such that the angle of one with respect to the other in the axial cross section changes in the middle of the dispersion region.

A dispersing device (1) has a dispersing tool (3), which has a shaft tube (2), and a drive (4). A dispersing rotor is provided at the free shaft tube (2) end (5) remote from the drive (4), the dispersing rotor being connected to the drive (4) via a shaft which can be coupled to the drive (4) and which is arranged within the shaft tube (2). In order to monitor the temperature of the medium to be dispersed, a temperature sensor (7) with a corresponding electric input and output line (8) is provided on the shaft tube (2), which is stationary relative to the dispersing rotor and the rotatable shaft, the input and output lines (8) connecting the temperature sensor (7) to the drive (4) and/or analyzing electronics and/or a control or regulating device.

A method of processing a liquid including (a) passing a flow of the liquid through a local constriction into an outlet channel, the flow of liquid having a velocity of at least 1.4 m/s at the exit end of the outlet channel, the flow of liquid in the outlet channel containing cavitation bubbles, and (b) collapsing the cavitation bubbles by subjecting the cavitation bubbles to a water hammer hydraulic pulse pressure resulting from periodically rapidly closing the outlet channel. A device for practicing the method is also disclosed.

A mixing system mixes liquid adhesive and gas to create a solution. The mixing system it a manifold defining an adhesive input that receives the liquid adhesive, a gas input that receives the gas, a mixing chamber in fluid communication with the adhesive and gas inputs, an output that outputs the solution, and an output passage extending from the mixing chamber to the output. The mixing system also includes a rotor that rotates within the mixing chamber about a longitudinal axis so as to mix the solution, a motor that rotates the rotor, and a static mixer positioned within the output passage that statically mixes the solution flowing through the output passage.
