The present invention relates to a milk frother assembly which makes the two stirrers rotate forward and reverse respectively, by using the reversing drive mechanism, rotating rod one, rotating rod two, a carabiner and two stirrers, so as to achieve the advantage of more efficient milk frothing and controlling of the quality of milk bubbles. The assembly allows through its novel setting of the length adjustment mechanism, to manually slide the slide plate, then move the rotating rod two through the sleeve and the connecting rod, and then adjust the position of the inner stirrer head, which is suitable for making milk froth in various capacities.

A fertilizer grinding mechanism, a water and fertilizer mixing device, and an aqueous fertilizer solution preparation production line. A fertilizer receiving body, where an edge is provided with a arranged first channel; a connecting body, fixed to a bottom of the fertilizer receiving body and provided with a second channel with the first channel, a bottom of the second channel is communicated with a buffer bin, a pushing block is arranged in the buffer bin, and the pushing block is connected with a drive mechanism for driving the block to move in direction of the body; and an inner grinding block, where the block is fixed to a bottom of the connecting body, an outer side of the inner grinding block is with a vertically movable grinding roller, the pushing block can push fertilizer under vertical movement of the roller. The grinding mechanism has a heat dissipation effect.

The present invention is a dust shield device that secures over a mixing pail. Powdery material, such as plaster, cement, grout or the like, is poured through the device, and mixed with water inside the pail. The device includes a mounting sleeve, a radial manifold housing and a funnel shaped lid. The manifold housing and lid form a radial pneumatic channel with a circumferentially disbursed air intake that generates a radially uniform airflow that draws in airborne dust that would otherwise escape to the surrounding air. The manifold is connected to a vacuum with an air filter, and generates a dust shield zone and air intake zone above the device. The manifold lid forms a radial guard to prevent downward flows of material and water from entering the manifold, and forms a splash guard to retain upwardly projected splashes of material and water inside the pail.

A mixing beater for a stand mixer includes a collar configured to removably couple the mixing beater with the stand mixer. A frame is coupled with the collar and includes a pair of opposing first and second arms. The first and second arms are coupled at their respective distal ends by a frame tip. A central axis of the mixing beater extends through the frame tip, between the opposing first and second arms. A plurality of ribs extends between the first and second arms. Each rib has a rib central axis that extends orthogonal to the central axis of the mixing beater and each of the plurality of ribs is spaced from an adjacent rib to define a space between adjacent ribs.

A funnel accessory for a KitchenAid® brand stand mixer with a hub protruding from its motor head. The funnel accessory has a funnel, with a top opening relatively larger than a bottom opening, affixed to a mount having a hub receiving opening oriented so as to be perpendicular to the top opening of the funnel. The mount is formed with a slot sized to receive a thumb screw of the hub; pushing the mount over an external wall of the hub while aligning the slot to receive the thumb screw couples the funnel accessory to the hub.

The device (1) for bringing a gas and a liquid into contact includes an enclosure (E), first means (5) for introducing into the enclosure and circulating therein a gas stream (G), second means (6) for introducing into the enclosure and circulating therein a liquid stream (L) that circulates inside the enclosure (E) in the same direction as the gas stream (G), and means (4A) for mixing the gas stream (G) and the liquid stream (L). These mixing means (4A) are positioned inside the enclosure (E) in the path of the gas stream and liquid stream and are capable of locally deflecting upward, and/or of locally causing to rise, at least one portion of the gas stream and liquid stream, so as to locally create turbulences in the gas stream and in the liquid stream.

A reactor filter washer dryer (R-FWD) apparatus and methods of using the apparatus for producing washed and dried product of a reaction is disclosed. The R-FWD comprises a vessel defining a process chamber, a filter plate laterally disposed on the vessel base, an agitator assembly, a solids discharge port in the vessel operable to remove the solid fraction of the slurry retained by the filter plate, and a filtrate outlet in the vessel for outflowing the liquid phase of the slurry filtered through the filter plate.

A cement mixing tool with a gearbox transmission assembly, an electric drill tool, a pair of mixing blades, a drive shaft housing assembly, a handle assembly and a splash guard. The electric drill tool is attached to the drive shaft housing assembly. The gearbox transmission assembly is attached to the drive shaft housing assembly. The pair of mixing blades are attached to opposing shafts extending from the gearbox transmission assembly. The splash guard attached to the exterior the drive shaft housing assembly. The handle assembly is attached to the drive shaft housing assembly. The resulting tool can be used by a person to mix wet cement within a wheelbarrow or other similar open topped container.

An antibody-resin coupling apparatus quickly and efficiently activates resin beads and couples them to antibodies, while preventing breakdown and crosslinking of the beads, thereby improving downstream column purification processes, extending the usable life of the resin beads, and increasing molecule capture efficiency of the resultant resin-antibody complexes, to allow improved isolation and purification of factor VIII molecules or other drug compounds.
