An apparatus can include a hollow tube, central shaft, agitation components, and bidirectional fluted auger. The hollow tube can have an inlet, outlet, and longitudinal central axis, and can facilitate the conveyance of foodstuff materials from the inlet to the outlet. The central shaft can extend along the longitudinal axis and can be rotationally driven both clockwise and counterclockwise. The agitation components can be coupled to the central shaft and can agitate and mix foodstuff materials being conveyed along the hollow tube. The bidirectional fluted auger can be coupled to the central shaft proximate the outlet, can rotate with the central shaft when the central shaft is rotationally driven, and can have a flow rate limiting inner cylinder, clockwise-progressing flute features, and counterclockwise-progressing flute features. The clockwise and counterclockwise progressing flute features can convey foodstuff materials toward the outlet when the bidirectional fluted auger is rotated clockwise or counterclockwise.

A blender has a tubular mixing chamber that is provided with an interior and is arranged horizontally. A fill opening and an outlet opening communicate with the interior of the tubular mixing chamber. The fill opening and the outlet opening are spaced apart from each other in an axial direction of the tubular mixing chamber by a length distance. A rotatably driven shaft extends in the axial direction lengthwise through the interior of the tubular mixing chamber and is provided with mixing members that are projecting radially outwardly into the interior of the tubular mixing chamber. The shaft has a region without mixing members, wherein the region without mixing members is located in front of the outlet opening and adjoining the outlet opening. The region without mixing members has a length that amounts to between ⅕ of the length distance and ½ of the length distance.

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 reactor system includes a support housing having an interior surface bounding a chamber, the chamber having a vertically extending central longitudinal axis. A flexible bag is disposed within the chamber of the support housing and has an interior surface bounding a compartment. A mixing element is disposed within the compartment of the flexible bag. A drive element, such as a drive shaft, is secured the mixing element, wherein the mixing element is laterally offset from and/or is angled relative to the vertically extending central longitudinal axis of the support housing.

A stirring device of a plug-flow fermentation device includes a shaft rotatable about an axis of rotation which defines an axial direction. The stirring device further includes a boundary stirring element that defines the axial extent of a stirring volume covered by the stirring device. A nearest neighbor of the boundary stirring element in the axial direction has an axial maximum width which is smaller than an axial maximum width of the boundary stirring element and which is larger than an axial maximum width of a next-nearest neighbor of the boundary stirring element.

An apparatus for mixing is disclosed. In embodiments, the apparatus includes a head, a shaft, and a base. In embodiments, the shaft couples to the head and includes a first opening at a bottom portion of the shaft. In embodiments, the base couples to the bottom portion of the shaft and includes a second opening that extends through the base and is aligned to the first opening.
