The invention belongs to the technical field of stirring equipment, and particularly relates to a stirring machine for dispersing of fermented bean curds. The stirring machine comprises supports, rotating motors, a rotating shaft, a stirring box, sealing caps and locking structures. A feed inlet is arranged at the top of the stirring box. A hexagonal cavity body of a discharge outlet is arranged at the bottom of the stirring box. The sealing caps are arranged at the feed inlet and the discharge outlet of the stirring box through hinges. The rotating shaft is fixedly arranged at the centers of two side walls of the stirring box, and is connected with the rotating motors. The rotating motors are arranged on the supports. The locking structures comprise upper fasteners and lower fasteners, and the upper fasters are matched with the lower fasteners. Two stirring shafts penetrating the stirring box are arranged on the side wall of the stirring box. Protrusion groups are arranged on the stirring shafts, and protrusions are arranged on the protrusion groups. Stirring blade groups are detachably connected with portions, between adjacent protrusions, on the stirring shafts. The stirring machine for dispersing of the fermented bean curds has the advantages that impact to inner corners of the stirring box is reduced, service life of the stirring box is prolonged, and liquid leakage is avoided.
