Apparatus for mixing a powdered material with a liquid that includes a housing in which a working space having an inner wall is arranged and a rotatably-driven rotor being arranged in the working space. The rotatably-driven rotor includes a blade ring and bars, which are pointing toward the inner wall and are arranged at different positions in a circumferential direction of the rotor. The apparatus also includes a feed opening for the powdered material being arranged above the blade ring and an annular gap connectable to a liquid supply arrangement being arranged below the blade ring. In a direction parallel to an axial direction of the rotor, the bars one of connect to one another or overlap one another.

An apparatus and method for processing a foodstuff comprises a closed conveyor path, a conveyor device, and a treatment chamber. The conveyor path includes an inlet and an outlet. The conveyor device is positioned within the closed conveyor path and configured to receive the foodstuff from the inlet. The conveyor device is further configured to convey the foodstuff along the closed conveyor path toward the outlet. The treatment chamber is positioned within the closed conveyor path downstream of the conveyor device for receiving the foodstuff from the conveyor device. The treatment chamber includes a rotatably driven first kneading shaft configured to collide the foodstuff within the treatment chamber.

An air-stirred tank reactor (ASTR) and methods of use thereof are described herein. The ASTR is equipped with an impeller or set of impellers that mechanically mixes a liquid culture, as well as sparges gas into the liquid medium. The impeller can further have lighting sources that can illuminate the liquid culture. Unlike conventional bioreactors, the ASTR provides superior liquid mixing, efficient gas mass transfer, and a low-shear culture environment through appropriate impeller rotational speed and sparging rate.

A liquid polymer or chemical activation system, having a chamber; a top cover plate, a middle cover plate and a bottom cover plate; wherein such configuration creates a hollow space inside the chamber that is flanked by the top cover plate and the bottom cover plate; a blending reactor with one or more inlets for receiving one or more substances; an upper multistage mixing cup configured to receive the one or more substances from the one or more inlets; at least one high shear mixer for mixing the one or more substances; at least one submersible actuator for actuating the high shear mixer; an intermediate blending section for receiving the one or more substances from the upper multistage mixing cup; a lower multistage aging cup for further mixing of the one or more substances; and at least one outlet on the bottom cover plate for releasing the one or more substances.

A printhead for an additive manufacturing system includes a hopper, an outlet, a mixing shaft, and a drive shaft. The hopper includes an inner volume configured to store a slurry material for mixing. The outlet includes a passageway fluidly coupled with the hopper. The outlet includes an open end for discharging the slurry material to a surface through the passageway. The mixing shaft extends through the inner volume of the hopper and includes a member that extends radially outwards from the mixing shaft. The member is configured to mix the slurry material within the hopper as the mixing shaft rotates. The drive shaft extends through the inner volume of the hopper and at least partially into the passageway of the outlet. The drive shaft includes a sloped surface configured to drive the slurry material from the hopper to the surface through the passageway of the outlet.

Embodiments of a system and a method for continuously manufacturing a joint compound can be used to produce ready mix joint compound. The system includes means for continuously mixing wet and dry joint compound ingredients together and means for homogenizing multiple volumetric units of mixed joint compound to reduce variation in at least one joint compound material property (e.g., viscosity) across multiple successively produced volumetric units of mixed joint compound (relating to standard commercial packaging sizes for joint compound, such as five-gallon pails, for example) relative to the material property of the respective multiple volumetric units before passing through the means for homogenizing.
