A mechanism for generating an orbital motion for mixing a fluidic sample. The mechanism may comprise a first and second cogwheel each having a through hole and a plurality of cogs. A drive shaft having a concentric first section and an eccentric second section is guided through a respective through hole of the first and second cogwheel. A coupling body engages part of the cogs to thereby generate the orbital motion of the second cogwheel and a sample holder to be mounted so as to follow a motion of the second cogwheel upon rotating the first section of the drive shaft.

A system for receiving a single-use vessel containing a mixing device has a support structure adapted to receive the single-use vessel and a drive-unit adapted to power, to control, or to power and control a mixing of contents of the single-use vessel when the single-use vessel is arranged in the support structure. The support structure and the drive-unit are provided as separate components that may be arranged both in an operating position, where the drive-unit is connectable to the mixing device of the single-use bag in the support structure, and in a separated position, where the drive-unit is separated from the support structure. The drive-unit comprises a tag reader that, in the operating position, is arranged to read a vessel tag of the single-use vessel arranged in the support structure.

A pug mill having a housing and a cantilevered shaft extending through the housing includes, in seriatim, a vacuum chamber, a wall, a mixing chamber and a reduction cone. A communication port about the shaft is positioned in the wall between the vacuum chamber and the mixing chamber. Vacuum can be maintained within the mixing chamber by air passing through the port. An auger associated with the shaft forces clay toward the reduction cone. This creates a seal for maintaining vacuum within the mixing chamber and extrudes cylindrical blocks of conditioned clay without significant air bubbles. A deflection plate rotating with the shaft and a spiral element about the shaft keep the communication port clear. The shaft is eccentrically mounted. The dividing wall is removable.

A mobile mixing apparatus for ensuring optimal mixing of a material includes a support member which is mobile on a support surface. A mixing drum is carried by the support member. The mixing drum has a base drum end, a side drum wall extending from the base drum end, an open drum end opposite the base drum end, a drum interior extending between the base drum end and the open drum end, a central inner surface and a base inner surface on the base drum end and a side inner surface on the side drum wall and facing the drum interior. A paddle assembly is disposed for rotation in the drum interior of the mixing drum. The paddle assembly includes a plurality of paddles engaging the central inner surface, the base inner surface and the side inner surface, respectively, of the mixing drum. At least one motor drivingly engages the paddle assembly for rotation in the drum interior of the mixing drum.

The invention relates to a rotor (10) of a dual centrifuge which can be rotated about a drive axis (A) in a centrifuge, which rotor comprises at least two rotary units (26) that are arranged symmetrically to one another and have a bearing (32) and a rotary head (30) which is connected to the bearing (32) and which is mounted in the bearing (32) so as to be rotatable about a rotational axis (R1, R2), which rotary head (30) can be driven about the rotational axis (R1, R2) relative to the rotor by another rotary mechanism (46) of the centrifuge and has a rotary head receiving unit (80) for at least one sample container or at least one sample container receptacle (100, 110), with the rotational axis (R1, R2) of the rotary head (30) being inclined relative to the drive axis (A) of the rotor, the rotary head receiving unit (80) being designed to receive an elongated sample container receptacle (100, 110) or an elongated sample container, and the longitudinal axis of the sample container receptacle (100, 110) introduced into the rotary head receiving unit (80) or the longitudinal axis of the sample container introduced into the rotary head receiving unit (80) extending perpendicular to the axis of rotation (R1, R2) of the rotary head (30) or being oriented at an angle ranging between more than 0 and less than 90 relative to the axis of rotation. According to the invention, at least one connection region (52) is provided to which at least one damping mass (54) can be selectively attached either in a releasable manner or, by means of a fixing element, in a permanent manner for operation.

A control method and control system for an agitating mechanism are provided. The control method includes receiving a load current detected by a current detecting apparatus when the agitating mechanism is rotating along a specific direction; determining whether the rotation of the agitating mechanism meets a preset trigger condition based on the load current; and controlling the agitating mechanism to rotate in a direction opposite from the specific direction when the trigger condition is met. The present invention can reduce the possibility of the electrical components of the agitating mechanism being burnt out and prolong the lifespan of the agitating mechanism. The present invention can improve agitation results of the agitating mechanism. At low speed, the agitating mechanism can perform the agitation gently without damaging the texture of the solid food. At high speed, the agitating mechanism can more homogeneously and finely agitate the mushy food with enhanced agitating efficiency.
