An agitator rotor includes a shaft, rails, and a rod. The shaft defines a longitudinal axis. The rails extend radially from and are coupled to the shaft. The rails are separated from each other along a length of the shaft. Each rail includes a surface defining a non-zero angle with respect to the longitudinal axis of the shaft. The rod includes a first end coupled to a first one of the rails. The rod includes a second end coupled to a second one of the rails. A projection of the first end and the second end of the rod in a plane perpendicular to the longitudinal axis of the shaft defines a minor arc about a portion of the shaft.

A stirring unit of a machine for making liquid or semi-liquid food products, including: a first base element rotatable about a first axis and having a plurality of first mixing vanes and a plurality of scraping appendages connected to the mixing vanes; a first actuator, connected to the base element to set it in rotation about the first axis, a second base element rotatable about a second axis and having a second mixing vane; a processing container forming a processing chamber for processing a base product and in which the first base element and the second base element are mounted; a second actuator, connected to the second base element to rotate it, the first base element and the second base element being configured to rotate independently of each other and the first actuator and the second actuator being configured to be activated independently of each other.

A mixer unit comprising a mixing chamber is disclosed. In one example, the mixing chamber comprises a de-agglomerator with a de-agglomeration shaft with de-agglomeration paddles, and a mixer with a mixer shaft with two or more mixing paddles that are arranged for mixing and impelling particles and powders in an upstream direction towards the de-agglomerator, whereby the de-agglomeration shaft is arranged above, and in parallel with said mixer shaft, so that all particles will be impelled towards the de-agglomerator, each time particles are lifted. A first portion of the mixing chamber may also have an inner profile adjacent and curved about an upper part of the de-agglomerator and is arranged to guide particles and powders impelled by the mixing paddles over the de-agglomeration shaft and into a liquid spray.

A base unit device for effective mixing and dispensing of a material, and for quick and efficient cleaning of all components. The base unit defines a base internal cavity, and a removable auger and a removable mixer each rotatably located in the base internal cavity. A mixer support ledge of the mixer can overlap an auger support ledge of the auger to prevent the auger from being withdrawn from the base unit when the mixer and the auger are operatively assembled with the base unit. The mixer can include a locking end featuring locking tabs that can engage with a surface of a sidewall of the base unit that defines a mixer bore, thereby locking the mixer and the auger in position during operation. The base unit can be utilized with a hopper defining a hopper internal cavity for storing the material and providing it to the base internal cavity.

Provided is a mixing apparatus. The mixing apparatus comprises a housing defining a primary chamber, an inlet for receiving material into the mixing apparatus, as well as an outlet for discharging material from the mixing apparatus. The housing provides within the primary chamber a plurality of rotating shafts, each rotating shaft having a plurality of flailing fixtures associated therewith.

Provided is a dust stop device for a sealed kneader, the device being capable of excellent supply of lubricating oil. The sealed kneader includes a pair of rotors and a supporting member. The dust stop device includes a rotating ring attached to each rotor and a stationary ring attached to the supporting member. Both the rings have respective contact surfaces which make surface contact with each other. The stationary ring has a lubricating-oil supply portion with a through-hole. A part of the through-hole, the part including a part opened in the contact surface, is a long hole extending along a circumferential direction of rotation of the rotating ring.

A method for operating an agitating device and a digester, wherein the digester is filled with a substrate and an agitating device is in the digester. These steps are performed: a) A target load curve is lodged in the control device; b) the control device prescribes a target rotation speed; c) the control device operates the agitating device at an actual speed corresponding to a target speed; d) the control device captures an actual agitating device torque measurement value at the actual speed of rotation; e) the control device derives from the actual measurement value an actual characteristic value of the agitating device applied torque; f) the control device compares the derived actual characteristic value against the target characteristic value of the substrate resulting from the target load curve at the prescribed target speed; and g) the control device controls the agitating device in dependence on the result of comparison.
