The invention relates to an apparatus (2) for mixing powdery baking ingredients with water. The apparatus (2) comprises a mixing chamber (4) which is inclined at a gradient and is preferably vertical, which has in an upper head region (6) at least one opening (8) for powdery baking ingredients falling into the mixing chamber (4) and in which there is arranged at least one nozzle (10) from which water (12) is ejected at a pressure of at least 30 bar from at least one nozzle opening (14). The nozzle opening (14) is directed at a mechanical obstruction (16) within the mixing chamber (4). Water (12) spraying out of the nozzle opening (14), together with the supplied baking ingredients, impacts the obstruction (16) in an impact region (20). Below the mixing chamber (4) there is arranged a container (24) which is provided with a cover (22) and which is connected, in a dough-conveying manner, to a discharge opening (26) of the mixing chamber (4). The apparatus has a suction device (32) for baking ingredient dust from the container (24), which has a suction opening (34) on the container (24), an inlet opening (36) into the mixing chamber (4) and a recycling duct (38) that connects the suction opening (34) to the inlet opening (36). Thus, the suction opening (34) is arranged in the head region (40) of the container (24) and the inlet opening (36) is arranged above the impact region (20) in the mixing chamber (4).

A multi-component mixing device including at least a first supply of a first product and a second supply of a second product. The mixing device has a mixing chamber having at least a first inlet and a second inlet, the first supply opening into the mixing chamber at the first inlet and the second supply opening into the mixing chamber at the second inlet. The mixing device includes a nozzle arranged and adapted to inject the second product from the second supply into the mixing chamber as a flat jet. An associated mixing method is also provided.

A fuel injection system (4) for an internal combustion engine has a low-pressure pump for delivering fuel from a fuel tank. The fuel is fed upstream of an injector (11) of the fuel injection system (4) to a mixing device (14). The mixing device (14) has a mixer housing (18) with a fuel connection (15) for receiving fuel and with at least one coolant connection (17; 28; 33) for receiving a coolant. For the purpose of bringing about efficient mixing of the fuel and the coolant, before a collision of a fuel jet (40) of the fuel and a coolant jet (41) of the coolant, the two fluid jets (40, 41) are formed to be at least partially aligned in the same direction.

A polymer activation assembly is provided for separating monomer from the oil in which it is suspended in a polymer forming suspension and mixing the monomer with water supplied from another stream. The supply water is supplied through a primary fluid channel extending through the activation assembly and which transitions to a relatively wide rectangular activation channel. A secondary fluid inlet is formed in a side of the activation assembly for injection of the polymer forming suspension therein. A nozzle section of the secondary fluid inlet is formed between an initial section of the inlet and the activation channel. The nozzle section is generally rectangular in cross section and relatively shallow. The distal end of the nozzle section has a width that approximates the width of the activation channel. The nozzle section angles at an acute angle toward the outlet.

A gas solution production apparatus 1 includes a gas dissolving unit 5 that dissolves the gas of the second raw material into the liquid of the first raw material to generate a gas solution with a predetermined concentration, and a gas-liquid separation unit 8 that subjects the gas solution to gas-liquid separation into a supply liquid and an exhaust gas. The unit 5 includes a first nozzle 9 that atomizes the liquid of the first raw material, a mist mixing section 11 that mixes the liquid of the first raw material atomized by the nozzle 9 and the gas of the second raw material to generate a gas solution with a higher concentration than a predetermined concentration, and a liquid mixing section 12 that mixes the gas solution with the high concentration and the liquid of the first raw material to generate the gas solution with the predetermined concentration.

A mixer for separate streams of gas includes a center stream of a first gas and a co-axial stream of a second gas injected at an angle to the center stream and filling an annulus around the center stream. The mixer may further include a feed zone wherein the first gas is introduced into the mixer as the center stream and the second gas is introduced into the mixer as the co-axial stream filling the annulus around the center stream; a mixing zone wherein the first gas and the second gas mix with no recirculation zones to form a mixture; and a diffusion zone for advancing the mixture from the mixing zone. Corresponding or associated methods for mixing materials are also provided.
