Abstract
An improved agitator structure for use in mixers for baking dough and other such food products and the like providing for improved mixing performance and speed, and useable in single-agitator or multiple-agitator embodiments, comprises an open, 'shaftless' structure which incorporates straight and flat (i.e. planar) mixing blades as opposed to twisted or other complexly-curved blades, and incorporates a pair of mutually-spaced hubs aligned with one another along an axis of rotation, a pair of mutually-spaced mixer blades located generally on opposite sides of the rotational axis and extending generally longitudinally thereof along a different portion of such axis, with each such mixer blade disposed at a longitudinal angle with respect to such axis and each being connected to at least one of the hubs for rotation therewith about said axis. Each of the mixer blades comprises a generally planar member having a curved outer edge which lies substantially within the plane of its associated mixer blade, with the curved outer edge of the mixer blades defining a cylindrical service of revolution upon rotation of the blades about said axis.
