A knife for attachment to auger flighting for a bulk mixer is provided. The knife comprises an exterior cutting side, a leading end defined as the front end during rotation of the auger, a trailing end opposite the leading end. The knife includes an inboard side adapted for attachment to the auger flighting. The exterior cutting side comprises a blade edge therealong for engaging material to be cut; an angled section along a portion of the blade edge, angled upward from horizontal (angled upward from the longitudinal plane of the knife) by X°. A base knife for attachment directly or indirectly to a bottom flight of an auger flighting in also provided.

An apparatus for aerating bodies of water includes a floating platform, a motor supported by the floating platform, a transmission which is coupled to the motor and whose output shaft is in the form of a hollow shaft, a fan for supplying air through an air supply line connected thereto, wherein the air supply line is connected to one end of the hollow shaft, a hollow stirring shaft coupled to the other end of the hollow shaft, an stirrer affixed to the free end of the approximately vertical stirring shaft, wherein the stirrer is designated as a hollow body and has a central opening through which air supplied by the stirring shaft can pass, and a multiplicity of air outlet openings.

A bale ripper assembly for pulling plant material from a bale may comprise a bale ripper device supportable on an auger of a feed mixer apparatus and having a first face and a second face with a perimeter. The perimeter may include a leading perimeter portion for orienting in a direction of movement of the device when the device is mounted on the auger of the mixer apparatus and the auger is rotated. The leading perimeter portion of the perimeter may include a plurality of sections with each section of the plurality of sections being oriented at an angle with respect to an adjacent said section of the leading perimeter portion. An outboard pair of the sections form an outboard tooth of the bale ripper device. The leading perimeter portion of the perimeter may have an edge face that extends between the first and second faces, and the edge face may be blunt.

The mixing or dispersing device and assembly equipped with such a device are proposed for optimizing the processing of mixed or dispersed substances, in particular tablets and/or capsules for medicinal drugs. The mixing or dispersing device includes in a mixing chamber, a motor-driven rotor having at least one cutting projection that has at least one cutting edge. A flow-disturbing element is further provided on an inner circumferential wall of the mixing chamber that surrounds the axis of rotation. Furthermore, a deflection surface is provided between the inner circumferential wall and a bottom of the mixing chamber. The at least one flow-disturbing element is spaced from the bottom of the mixing chamber, from the at least one cutting projection and from the circular path on which the at least one cutting projection is movable about the axis of rotation.

A food preparation appliance has a base, a blade member rotatable in a direction of rotation, and a container with a closed bottom, an open top and a tubular sidewall together defining an interior space of the container. The top of the container is configured for releasable connection with the base, with the blade member disposed within the interior space of the container. The sidewall has a rib projecting inward of the interior space of the container and extending lengthwise along at least a portion of the sidewall from the top of the container toward the bottom of the container. The rib has, in the direction of rotation of the blade member, a peak defined as the shortest transverse dimension measured from the center of the container to the sidewall at a respective height along the portion of the sidewall having the rib, the rib being asymmetric in transverse cross-section.

A peanut butter mixer system including: a screw-mixer formed as a continuous rod member having sequential looped coils along a length of said continuous rod member and terminating with a cutting edge; wherein said screw-mixer is powered via a motor and a power source as manipulated by a user-operator to re-mix peanut butter in a provided container. The screw-mixer is powered via the motor and power source as manipulated by a user-operator.
