Abstract:
A method for extruding a comestible material comprises the steps of passing comestible material into an extruder (100) with rotation of the extruder screw(s) (120, 122) and delivery of fluid comprising steam and water into an opening (114a) of the extruder barrel (104). The fluid delivery step comprises separately directing individual quantities of steam and water into the casing (72) of a static mixing section (54), and blending the steam and water to create a blended mixture, and then delivering the blended mixture into the barrel (114a). The blended mixture is delivered to the barrel opening (114a) by a conveying assembly (84, 86) having a pipe assembly (86) with an outlet in communication with the barrel opening (114a); the pipe assembly (86) and opening (114a) have diameters less than maximum internal diameter of the static mixer casing (72).
Abstract:
The invention relates to a method for adding hops in beer manufacture, having the following process steps; a) separation of a sub-quantity (07a) of water and/or wort (07) and/or beer as an aqueous fluid, b) addition of hop extract (10) in liquid or pasty form to the separated aqueous fluid (07a), c) production of a macroemulsion (13) of the hop extract by emulsifying the hop extract (10) in the aqueous fluid (07a), d) increasing the pressure in the macroemulsion (13) of the hop extract to a feed pressure of in particular higher than 100 bar, e) production of a microemulsion (17) of the hop extract by feeding the pressurized macroemulsion (13) through a gap or a valve (16) or by feeding the pressurized macroemulsion against a baffle plate, f) at least partial return of the microemulsion (17) of the hop extract to the beer manufacturing process.
Abstract:
A mixing apparatus includes a main agent supply unit that supplies a main agent to a main agent pipe and a curing agent supply unit that supplies a curing agent to a curing agent pipe. A mixing pipe, with which the main agent pipe and the curing agent pipe merge and through which the main and curing agents pass, has a static mixer and a dynamic mixer that sequentially mix the main and curing agents. A discharge pipe discharges a sealant obtained through the static mixer and the dynamic mixer. An in-system decompressor sets at least the static mixer and the dynamic mixer in a decompressed atmosphere before the main and curing agents are mixed.
Abstract:
A system for dispersing a catalyst in a fuel includes a first reservoir containing the fuel, and a second reservoir including an agitator and containing a quantity of the catalyst suspended in the fuel. The system also includes a first conduit extending from the first reservoir, a second conduit extending from the second reservoir, and a mixing nozzle connected to the first conduit and the second conduit. The mixing nozzle includes a first meter positioned within the first conduit, a second meter positioned within the second conduit, a valve positioned upstream from the second meter within the second conduit, a junction in flow communication with the first conduit and the second conduit, a mixer downstream from the junction, a sensor positioned between the mixer and an outlet; and a controller connected to the valve and the first and second meters, the controller receiving feedback from the sensor.
Abstract:
Disclosed is an apparatus and method for manufacturing high-performance concrete by introducing air into normal concrete and dissipating air, wherein high-performance concrete is formed in a manner in which bubbles, which are to be removed, are added in a large amount together with an admixture to pre-blended normal concrete so that the admixture is uniformly dispersed in the normal concrete using the ball-bearing effect of the bubbles, thus forming mixed concrete, and the mixed concrete is discharged using air at a high pressure of 5 atom or more to thereby shoot high-performance concrete of which the slump, remarkably increased due to the large amount of bubbles, is reduced to fall within the range of slump of normal concrete while dissipating excess air from the mixed concrete.

Fracturing process employing the preparation center.
Abstract:
Apparatus (20) for injection of fluid into extrusion system components such as a preconditioner (24) or extruder (100) is provided, preferably as a composite assembly including a fluid injection valve (52) and an interconnected static mixer section (54). Alternately, use may be made of the fluid injection valve (52) or static mixer section (54) alone. The invention greatly simplifies the fluid injection apparatus used in extrusion systems, while giving more efficient absorption of thermal energy with a minimum of environmental contamination, and the ability to inject multiple streams into the extrusion systems.

An improved method for the manufacture of an oil-in-water emulsion comprises using a microfluidisation device whose interaction chamber comprises a plurality of Z-type channels upstream of a back pressure chamber.
Abstract:
A dynamic mixer for a plurality of fluid components contains a housing and a rotor element which is rotatably arranged in the housing, with the housing having an inlet opening for at least one respective component and having at least one outlet opening. A ring-shaped intermediate space is provided between the rotor element and the housing in which a mixing element connected to the rotor element is arranged. The mixing element has a vane element which is formed as a directing element for conveying the components from the inlet opening to the outlet opening. The vane element is a directing element and has a directing surface which has a concave curvature with respect to the outlet opening and is further remote from the outlet opening at the onflow side than at the outflow side.
