Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. The aggregated particle slurry is heated, then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions.

Device for reintroducing vapour into a volatile liquid includes a tank for volatile liquid, a circulation pump and connected conduit for pumping liquid from the tank through a mixing zone or device for mixing vapour and liquid, and a conduit for conveying vapour from a space above the liquid level to the mixing zone or device. The mixing zone or device is arranged in a manner that ensures a pressure therein that is independent of the liquid level within the tank.

Mixing kneader (1) for carrying out a continuous extraction in which, with the aid of an extractant, at least one component is released from an extraction material, the mixing kneader (1) comprising a working space (2), at least one shaft (14) extending in the working space (2), the at least one shaft (14) comprising shaft superstructures (11, 12, 29) in the form of kneading elements, wherein the shaft superstructures (11, 12, 29) of the at least one shaft (14) are configured to mesh during operation with the shaft superstructures (11, 12, 29) of at least one second shaft (14) or with stationary kneading elements (17) present in the mixing kneader (1), a first feed device (4) for feeding the extraction material into the mixing kneader (1), and a first discharge device (3) which lies substantially opposite the first feed device (4) and discharges the extraction residue, is intended to be characterized by a second feed device (6) for feeding the extractant, wherein this second feed device (6) is arranged substantially opposite the first feed device (4), further characterized by a second discharge device (5) for discharging the extract solution, wherein the second discharge device (5) is arranged substantially opposite the first discharge device (3), wherein the second discharge device (5) comprises a device for mechanical separation.

A multi-layered micro-channel mixer includes a base plate and a cover plate. Two inlet fluid reservoirs, two inlet channels, two groups of fluid distribution channel networks, two groups of process fluid channels, an impinging stream mixing chamber, a fluid mixing intensification channel and an outlet buffer reservoir are provided on the base plate. Two fluids are fed into the two inlet fluid reservoirs, respectively. The fluids then flow into the process fluid channels via the inlet channels and the multi-stage fluid distribution channel networks, respectively. Then the two fluid streams ejected from the opposing process fluid channels impinges upon each other in the impinging stream mixing chamber. The mixed fluid is subjected to vortex or secondary flow generated by the baffles or the internals in the impinging stream mixing chamber and fluid mixing intensification channel, and finally the mixed fluid is discharged through the outlet buffer reservoir.

Provided is a fine bubble supply device and a fine bubble analyzing system capable of more stably supplying fine bubbles unstable in a liquid. A fine bubble generating device generates fine bubbles. A retention vessel stores a liquid therein, and an inlet pipe and an outlet pipe of the fine bubbles are connected to the retention vessel. The fine bubbles generated from the fine bubble generating device are introduced into the liquid in the retention vessel through the inlet pipe to be retained in the liquid. The fine bubbles retained in the liquid are led out to a supply destination (fine bubble characteristic evaluation device) through the outlet pipe.

A kneading apparatus has a housing and first and second rotary shafts mounted in the housing in parallel to one another for undergoing rotation about respective axes in opposite directions at unequal speeds to one another for kneading an object. The first and second rotary shafts have respective first and second stirring members arranged helically at a predetermined helical pitch and at predetermined angular pitch intervals, with the second stirring members being arranged with an inverse helix from that of the first stirring members. Side blocking plates disposed in the housing partially block the kneaded object and move it between the first and second rotary shafts. The side blocking plates are spaced apart from one another to provide a space above the first and second rotary shafts such that the kneaded object can pass through the space in the axial direction of the first and second rotary shafts.
