Method for efficiently cleaning rice polluted by heavy metal

The invention discloses a method for efficiently cleaning rice polluted by heavy metal. The method comprises the following steps that a certain amount of water is introduced into a cleaning tank witha magnetic roller, a cleaning liquid is added for uniform stirring, impurities are filtered out, the magnetic roller is energized to attract and discharge insoluble magnetic impurities contained in the riced, the filtered rice is cleaned again, the surface of the rice is scrubbed with a brush, filtration and drying are conducted after scrubbing is completed, and the dried rice is irradiated by ultraviolet rays and then photographed. According to the method, the rice is fully reacted and uniformly stirred with a lemon liquid in a closed environment with high pressure, so that the heavy metal isremoved more thoroughly, microorganisms carried by the rice can be removed to the maximum extent, and the sterilizing capability is improved; meanwhile, the rice is photographed for comparison, so that a processing effect is
