The invention provides an alkali refining mixer for refining
rice bran oil, which comprises a mixer shell, an alkali liquor adding port arranged at the top of the mixer shell, a
discharge port arranged at the bottom of the mixer shell, a stirring
assembly rotatably arranged in the mixer shell, and a power device arranged at the top of the mixer shell and used for driving the stirring
assembly to rotate, a mounting plate with a circular projection on the horizontal plane is fixedly arranged in the mixer shell, a bearing ring is arranged on the
peripheral ring of the mounting plate, an annular groove plate is connected to the exterior of the bearing ring, the stirring
assembly comprises a stirring shaft, a sun gear is fixedly arranged on the stirring shaft, and an inner gear ring is fixedly arranged at the bottom of the mounting plate; at least one group of
planet gears are rotatably arranged at the bottom of the groove plate, the
planet gears are respectively meshed with the sun gear and the inner gear ring, a stirring rod is fixedly arranged at the bottom of the groove plate, the stirring rod is of a hollow structure, the upper part of the stirring rod is communicated with the groove plate, and a plurality of liquid outlet holes are formed in the side wall of the stirring rod, so that alkali liquor and
rice bran oil can be fully mixed; the alkali refining effect is improved.
