At the same time, with the increasing demand of downstream enterprises for the quality of rice milling machinery products, they also put forward higher requirements for the quality and supporting services of rice milling machinery products. The bran is separated on the two-way inclined and reciprocating vibration separation plate by using the different specific gravity, particle size of rice and bran and the interaction of friction between the grain and the separation surface.

9. The method of using a grain processing dehuller according to claim 8, wherein: Specifically includes the following steps: Step one: by sending the grain to be processed into the inside of the feed hopper (2), using the feeding roller (7) to control the grain in the feed hopper (2) to enter the inside of the separation cylinder (5) through the feeding channel (6); Step two: after the rice is sent into the inside of the separation cylinder (5), the rice is separated into four areas in the inside of the separation cylinder (5) by the material separating frame (24) around the separation frame (21), then the output shaft of the servo motor (23) drives the separation frame (21) to rotate in the inside of the separation cylinder (5), controls the separation frame (21) to rotate 90° each time, makes two separated areas respectively above and below the separation frame (21), at this time, the movable baffle (27) on the top and bottom of the separation frame (21) is controlled to slide into the inside of the separation frame (21), and the material passing frame (26) is controlled to rotate, so that the rice in the upper separated area passes through the material passing groove (25) and falls into the lower separated area. In the process of the rice in the upper separated area falling to the lower separated area, the telescopic plate (29) slides into the inside of the material separating frame (24), and the air blowing frame (28) blows to one side of the material storage cavity (210), blows the bran and light impurities in the falling rice into the inside of the material storage cavity (210), and the bran is temporarily stored in the material storage cavity (210). Step 3: After the rice in the upper part has completely fallen into the lower part, control the movable baffles (27) at the top and bottom of the separating frame (21) to close the upper and lower parts of the feed trough (25), and at the same time, the telescopic plate (29) closes the inside of the storage chamber (210). Then control the separating frame (21) to rotate 90° and continue to separate the bran from the rice in the separated area. Step 4: When the rice is rotated inside the separation cylinder (5) by the separation frame (21) and the material separator (24), the driving end of the electric push rod (34) drives the adjusting screen (33) to slide at the bottom of the fixed screen (32), and adjusts the overlapping area of ​​the screen holes of the fixed screen (32) and the adjusting screen (33). The overlapping area of ​​the screen holes between the fixed screen (32) and the adjusting screen (33) is controlled to become larger and larger. When the rice passes through the fixed screen (32) at the bottom of the separation cylinder (5), the smaller broken rice in the rice will pass through the fixed screen (32) and the adjusting screen (33) and enter the inside of the material drop rack (8) to separate the broken rice in the rice. Step 5: After the control separator (21) rotates 90° inside the separator (5), one side of one of the separators (24) contacts the top of the discharge pipe (35). At this time, the automatic control valve on one side of the separator (24) is opened, and the movable plate (36) at the top of the discharge pipe (35) is opened, allowing the bran inside the storage chamber (210) to slide into the discharge pipe (35) under its own weight, and the bran is sent out using the discharge pipe (35). Step 6: When separating broken rice from rice using a fixed screen (32) and an adjustable screen (33), control one side of the guide plate (45) to contact one side of the inner wall of the discharge rack (8). After the broken rice enters the discharge rack (8), it is guided by the guide plate (45) to the inside of the guide rack (44). Finally, the broken rice is sent through the guide rack (44) into the second collection box (12) for centralized collection. When collecting whole rice, control the guide plate (45) to close one side of the guide rack (44). After the whole rice enters the discharge rack (8), the discharge plates (42) inside the discharge rack (8) make a slight impact on the whole rice, allowing the dust on the surface of the rice to be separated. At the same time, the dust pump (41) works with the dust rack (43) to suck up the dust inside the discharge rack (8).
