The invention belongs to the technical field of grain processing and particularly discloses a rice milling machine. The rice milling machine comprises a base, a first rice milling barrel and a first motor. The first rice milling barrel and the first motor are arranged on the base. The first rice milling barrel is horizontally arranged. The output end of the first motor penetrates the barrel wall of the first rice milling barrel and extends into the first rice milling barrel. A first rice milling roller is arranged on the output end of the first motor and located inside the first rice milling barrel. The lower portion of the first rice milling barrel is provided with a screening net. The base is fixedly provided with a second rice milling barrel, a second motor and an inclined conveying channel. One end of the conveying channel is located below the screening net, and the other end of the conveying channel communicates with the second rice milling barrel. The second rice milling barrel is horizontally arranged. A rotating shaft is coaxially arranged on the output end of the second motor. The rotating shaft penetrates two side walls of the second rice milling barrel. A second rice milling roller is fixedly arranged on the rotating shaft and is of a hollow netlike barrel-shaped structure. By means of the rice milling machine, the problem that rice needs to be milled multiple timesis solved.
