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). A secondary product introduction means protrudes into the intermediate mixing chamber (7) so as to issue into said intermediate mixing chamber (7). A method for aerating a pasty product is also provided.

Provided are an immediately-before-stirring-type fluid processing device and an immediately-before-stirring-type fluid processing method that can adjust or improve the final properties of a fluid to be processed that is introduced as a raw material into an annular flow channel of a microreactor employing the annular flow channel, which is formed between relatively rotating processing surfaces, as a flow channel in which fluid processing is performed. A fluid to be processed, which has been prepared in a fluid preparing system so as to be in an ideal state for reaction, is charged into a fluid processing device. The fluid processing device subjects the fluid to be processed to reaction processing in an annular flow channel, which is formed between two processing surfaces. A cylindrical stirring space is provided in the radially inner side of the annular flow channel, and a rotor and a screen are disposed inside the stirring space. Stirring energy is applied by the rotor and a shearing force is applied between the rotor and the screen to the fluid to be processed immediately before the fluid to be processed is introduced into the annular flow channel.

An apparatus for cutting polymer includes a rotor having a base with a first side and a second side opposite the first side. The rotor includes an outer annular wall extending from the first side and defining a number of slots, an inner annular wall defining a number of slots and extending from the first side and surrounded by, and spaced apart from, the outer annular wall. The rotor also includes blades extending from the first side and positioned within the inner annular wall. A circular-shaped stator also defines a number of slots. At least a portion of the stator is positioned in a space between the outer annular wall and the inner annular wall of the rotor.

Disclosed is a dispersing device, including a first shear device and at least two second shear devices, one of the first shear device and the second shear device is a shear stator and the other is a shear rotor. The first shear device includes a shear inner ring, a shear outer ring and an annular isolation board. The shear inner ring is provided with a plurality of first radial through holes; the shear outer ring is provided to surround outside the shear inner ring, and is provided coaxially with the shear inner ring and connected in linkage with each other; and the shear outer ring is provided with a plurality of third radial through holes. The annular isolation board is located between the shear inner ring and the shear outer ring, and both opposite ends of the annular isolation board form shear receiving grooves, respectively.

An improved method for the manufacture of an oil-in-water emulsion involves circulation of emulsion components between a first container and a second container via a homogenizer and/or via a microfluidization device. Usefully, all of the emulsion components from the first container are emptied before being returned.

A device (1) for mixing, in particular dispersing, includes a housing (2) with at least one inlet (3) and a grinding chamber (13). In addition, the grinding chamber (13) includes a first process region (4) for mixing fed materials, wherein the materials are introducible into the first process region (4) through the at least one inlet (3), and a second process region (5) for diverting the mixture to an outlet (6) as well as a separating device (7) for separating the first process region from the second process region, and a rotor (8) for mixing, in particular dispersing the mixture in the first process region (4), wherein the rotor is drivable by a drive shaft (9). A pump (10) connected upstream is drivable by the drive shaft (9) and materials are feedable by means of the pump (10) into the first process region (4) and the first process region comprises a dispersion volume within the range of 11-501, in a preferred manner of 41-121 and particularly preferred is 61.

The present invention is directed to a special device for fast mixing and precipitation reactions of chemical substances. In particular, the present invention presents a reactor which allows an extremely fast mixing of at least two liquid streams containing highly concentrated dissolved materials from which solid metal compound particles are formed when at least two reactant streams meet, to which optionally a further stream, advantageously containing a dispersion or suspension, may be added.

An improved method for the manufacture of an oil-in water emulsion involves three procedures: (i) preparation of a preliminary emulsion; (ii) micro fluidization of the preliminary emulsion to reduce its droplet size; and (iii) filtration, of the microfluidized emulsion through a hydrophilic membrane. The emulsions are useful as vaccine adjuvants.

A fluid treatment apparatus is described. The fluid treatment apparatus includes: (i) a pulverizer designed to pulverize solids present in a fluid flow to produce pulverized solids admixed with the fluid flow; (ii) a rotatable shaft for rotating the pulverized solids and the fluid flow; (iii) a restrictor or filter for retaining a first portion of the pulverized solids, and allowing a second portion of pulverized solids and a second portion of the fluid flow to pass therethrough; and (iv) a first recirculating line configured to receive the first portion of the pulverized solids and a first portion of the fluid flow that did not pass through the restrictor or the filter.
