2. A method of operating a rice bran separation apparatus for rice as claimed in claim 1, the method comprising the steps of:

the method comprises the following steps: rice to be separated is poured into the loading frame (2), the rice falls into the upper part of the sliding plate (11), and the rice slides downwards along the sliding plate (11); after the rice is blocked by a plurality of baffle plates (13) on the upper part of the sliding plate (11) in the process of slipping, the slipping speed is reduced, and the rice is flipped after slipping to the baffle plates (13), so that rice bran inside the rice is flipped out; in the rice sliding process, a plurality of vibration pumps (12) at the bottom of the sliding plate (11) send vibration force to drive the sliding plate (11) to shake, and the rice slides downwards over the material baffle plate (13) along with shaking in the rice sliding process; during the rice shaking process, the rice bran inside the rice shaking device is shaken out, the first dust absorption port (15) absorbs the rice bran in the rice, and the rice bran and the rice are separated;

step two: in the use process of the sliding plate (11), a third driving motor is started to drive the sliding plate (11) to rotate in the first support (14), so that the inclination angle of the sliding plate (11) is changed, and the rice sliding speed is changed; meanwhile, the number and the types of the striker plates (13) can be changed according to actual needs, when the striker plates (13) are changed, the striker plates are pulled out from the upper part of the sliding plate (11), and the magnets (31) at the bottom are separated from the sliding plate (11); when the striker plate (13) and the sliding plate (11) are installed, the magnet (31) at the bottom is fixedly bonded with the top of the sliding plate (11);

step three: after being cleaned in the loading frame (2), the rice slides downwards from the bottom of the loading frame (2) and falls into the roller (6) from the feed port (17); the rotating rod (19) drives the rotating shaft (18) and the mixing rods (22) to rotate, the mixing rods (22) mix and stir the rice in the roller (6), the rice bran in the rice is turned out, the second dust suction ports (16) on two sides above the roller (6) absorb the turned rice bran, and the rice bran is further removed; after the rice is turned and cleaned in the roller (6), the fourth driving motor at the bottom drives the connecting plate (21) to rotate downwards, the sealing cover (20) is separated from the discharge hole at the bottom of the roller (6), and then the rice in the roller (6) is discharged outwards from the discharge hole;

step four: the rice drops downwards after being discharged from the discharge hole; a plurality of third dust suction ports (23) on the side surface of the side plate (5) clean the falling rice; the third dust absorption port (23) absorbs the rice bran in the rice; when the rice rotates in the roller (6), fine impurities and rice bran are separated from meshes and then fall downwards, and are adsorbed in the falling process;

step five: after the rice falls downwards to the upper part of the impurity removing mechanism (8), the impurity removing conveyor belt (26) drives the rice to move towards the bottom until the rice falls to the upper part of the material conveying conveyor belt (9) and is conveyed away; when the rice moves on the upper part of the impurity removing conveyor belt (26), the electrostatic adsorption plates (25) at two sides adsorb impurities in the rice, and the rice bran and the impurities in the rice are removed.
