Abstract: The present invention relates to a ceramic cutting teeth-dovetailed cutting device of a cutting-type rice milling machine. In general, a cutting tool is used to cut outer bran of brown rice in a cutting-type rice milling machine. Here, the cutting tool is configured of a combined body in which cutting rings and spacer rings are alternately combined, and the cutting rings have a ring shape with a uniform thickness and have an outer circumference on which gear-shaped trapezoidal cutting teeth are formed to cut outer bran of brown rice by edge portions of the cutting teeth such that white rice is produced. More specifically, the invention relates to a cutting device used in a rice milling machine, the cutting device having a configuration in which a main cutting-device body is dovetailed with cutting teeth.
