Hydration systems with adjustable agitation features

A method of processing foodstuff materials, the method comprising:

• providing foodstuff materials into a material passage having at least a bottom, one or more sidewalls, and an outlet, the material passage defining a longitudinal axis therethrough;
• rotating an inner shaft within the material passage about the longitudinal axis, the inner shaft having multiple protrusions extending therefrom that rotate with the inner shaft, wherein each of the multiple protrusions includes a post coupled to the inner shaft and a plowhead coupled to a distal end of the post away from the inner shaft, each plowhead having a driving surface configured to push the foodstuff materials, and wherein the driving surfaces of each of at least a first portion of the plowheads are arranged at an angle with respect to the longitudinal axis such that the first portion of driving surfaces push the foodstuff materials toward the outlet when the inner shaft is rotationally driven;
• inputting water into the material passage while the foodstuff materials are within the material passage to produce a plurality of hydrated foodstuff material particles;
• conveying the foodstuff materials through the material passage toward the outlet, wherein the conveying is at least partially facilitated by the first portion of driving surfaces pushing the foodstuff materials toward the outlet when the inner shaft and multiple protrusions are rotated about the longitudinal axis;
• agitating the foodstuff materials while the foodstuff materials are within the material passage;
• and
• collecting the foodstuff materials from the outlet of the material passage.
