The present invention relates to a continuous process for preparation of a stable agrochemical composition in microreactor processing system. The present invention also provides a stable agrochemical composition having mean particle size distribution and method of controlling undesired vegetation with said composition.

A mixing apparatus is described. The mixing apparatus has a first port for receiving milk, a second port for receiving steam, and a mixing chamber for mixing the milk, the steam, and air. A channel arrangement connects the first port and the second port, and defines an air intake channel which leads to a frothing section. The mixing apparatus is designed such that, in use, the frothing section fills sufficiently with steamed milk that has a direct path from the second port to the mixing chamber is interrupted by the steamed milk. This provides a noise reduction during use of the mixing apparatus. A flow reducing means, such as a barrier, may be used for this purpose.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.

The invention relates to a method for producing a beverage in portions, wherein a beverage concentrate portion is mixed with a water portion, said water portion being mixed with carbon dioxide prior to being mixed with the beverage concentrate. The invention additionally relates to a device for producing a beverage in portions, wherein a beverage concentrate portion is mixed with a water portion, said water portion being mixed with carbon dioxide in a static mixer prior to being mixed with the beverage concentrate.

The present disclosure relates to an extrusion apparatus comprising: a) a planetary roller extruder; b) a melt pump arranged downstream of the extruder; c) optionally, a fluid feeding equipment; d) a static cooling mixer equipment arranged downstream of the melt pump; e) a foaming equipment arranged downstream of the static cooling mixer equipment. The present disclosure also relates to a process of manufacturing a foamed polymeric composition and uses thereof.

A gas mixer (100), to which a first gas and a second gas are fed, mixes the two fed gases to form a gas mixture. A helical component (2) is arranged in an interior of an outer component (5). A helical mixing cavity (20) is formed between the outer component and the helical component (2). An additional mixing volume (6) is located in the interior of the outer component (5) or in the interior of the helical component (2). One gas is sent through a first feed line (31) to the helical mixing cavity (20), and the other gas is sent through a second feed line (32) to the additional mixing cavity (6). A gas mixture discharge line (40) discharges the produced gas mixture from the helical mixing cavity (20).

The application relates to microfluidic apparatus and methods of use thereof. Provided in one example is a microfluidic device comprising: a first fluidic input and a second fluidic input; and a fluidic intersection channel to receive fluid from the first fluidic input and the second fluidic input, wherein the fluidic intersection channel opens into a first mixing chamber on an upper region of a first side of the first mixing chamber, wherein the first mixing chamber has a length, a width, and a depth, wherein the depth is greater than about 1.5 times a depth of the fluidic intersection channel; an outlet channel on an upper region of a second side of the first mixing chamber, wherein the outlet channel has a depth that is less than the depth of the first mixing chamber, and wherein an opening of the outlet channel is offset along a width of the second side of the first mixing chamber relative to the fluidic intersection.

The present invention relates to a method and an arrangement for dissolving starch. Specifically, the present invention relates to a method for dissolving starch by introducing mechanical force to at least partially gelatinized agueous starch.

A high-gravity rotating bed device, including a motor, a rotor and a housing. The rotor and the motor are entirely arranged within the housing. A load-bearing plate is provided within the housing. The load-bearing plate divides the housing into a reaction chamber and a balance chamber. The motor is arranged within the balance chamber. A transmission shaft of the motor passes through the load-bearing plate and is fixedly connected to the rotor arranged within the reaction chamber. A gas inlet, a gas outlet, a liquid inlet and a liquid outlet are arranged on the housing. An externally communicating pipeline is arranged on the balance chamber. Also disclosed is an application of the present high-gravity rotating bed device under high-pressure conditions in operations such as mixing, transferring and reacting.

A mixing chamber is loaded with a first fluid. While a volume of the first fluid within the mixing chamber is constant, first and second streams of a second fluid are injected into the mixing chamber along first and second injection directions. As a result of injecting the first and second streams of the second fluid into the mixing chamber, the first and second streams of the second fluid impinge one another so as to generate within the mixing chamber at least one further stream of the second fluid that mixes with the first fluid and that flows in a direction different to the first and second injection directions.
