Abstract: A dough batch mixing process and apparatus where the ingredients are mixed first at a high rate of speed and then transferred for developing in a separate chamber. The blending of ingredients is performed by a helical shaped agitator without a central shaft which rotates to force the mix toward one end of the chamber. A common hatchway between the chambers is opened and the agitator spirals to force the mix through the opening into the second chamber for further development of the mix. After completion of the developing cycle, the fully prepared dough is exhausted from the chamber by two rotating roller bars which substantially pulls the entire mass from the chamber leaving limited waste behind. Each segment of the cycle is performed continuously so that a new fully developed dough batch is readied every one-half cycle time.
