A mixer for combining food constituents into a homogeneous mass includes an eccentric drive mounted on a mixing head of the mixer, where the eccentric drive is configured to rotate around a central axis of a mixing area and rotate an offset rotational axis of a drive shaft in an orbit about the central axis of the mixing area. An angled beater attachment for the mixer further includes a top mounting portion operably coupled to the drive shaft of the stand mixer, a bottom beater portion disposed above the mixing area, and a beater support member operably coupled with a support shaft of the bottom beater portion. The bottom beater portion is driven by the drive shaft about an angled rotational axis that extends at an acute angle relative to the central axis of the mixing area.

Chemical reactor with high speed rotary mixing, system thereof, and method thereof, for catalytic thermal conversion of organic (hydrocarbon-containing) materials (coal, plastics, rubber, plant matter, wood shavings, biomass, organic wastes) into diesel and other liquid fuels (automobile or/and jet engine fuels). Relevant to non-conventional commercial scale production of liquid fuels, and to commercial scale processing and disposing of organic waste materials. Chemical reactor includes: integrated combination of a reactor stationary assembly (RSA), having only stationary components remaining stationary during chemical reactor operation, and a reactor rotary mixing assembly (RRMA), having only rotatable components rotating during chemical reactor operation. May include anti-abrasion shield for shielding inner surface of reactor central housing from abrasion during chemical reactor operation. Rotor may include a reinforcement disc. Rotor blades or/and reinforcement disc may include rotor-based performance and process control structural features (openings, or/and protrusions, or/and depressions), for additionally controlling performance of the rotor.

The enclosed offset pail mixer is an invention which allows for safe, efficient and clean mixing of liquid solutions and liquid mechanical mixtures. The mixer includes a moveable head assembly that is constrained to two positions. In the operating position, the mixer geometry substantially encloses the moving parts of the mixer, preventing personnel from coming in contact with moving parts. The geometry also acts to contain dusts and vapors. A safety control circuit ensures that the impeller motor will not operate unless the vessel and the shroud are both in their respective operating position. In the operating position, the impeller shaft axis is strategically offset from the vessel axis to reduce large vortices and associated aeration. When the movable head is in the retracted position, the impeller is positioned over a removable drip cup to prevent residue from dripping on the floor or machine frame.

A mixing apparatus has a mixing container disposed in the upper part of the mixing apparatus, preferably standing on a frame, which is open towards the top. The mixing container includes a single-shaft agitator disposed in the lower part of the mixing apparatus. The agitator has a vertically disposed agitator shaft to which is fastened an agitating tool configured as a rotor body which is disposed in the mixing container just above the container base. The single-shaft agitator is a statorless agitator and the rotor body fastened to the agitator shaft is surrounded by an external free space between the rotor body and the container wall of the mixing container. The agitator shaft is adjustable in its spacing distance from the cylinder axis.

A sample agitation system for an automated sampling device is described. In an example implementation, the sample agitation system includes a sample probe configured to contact a sample positioned within a sample vessel. Further, the sample agitation system includes an actuator coupled to the sample probe that is configured to stir the sample positioned within the sample vessel in one or more rotational directions. The directions may include, but are not limited to, clockwise motion, anti-clockwise motion, or the like. In some implementations, a sample probe support arm can be coupled to the sample probe and/or the actuator. The actuator can move the sample probe support arm in a translational, a rotational, and/or a vertical direction to rotate the sample probe and stir the sample.
