Technical Field

[0001] The utility model relates to the technical field of rice processing and production, in particular to a magnetic separator for automated rice processing and production. Background Art

[0002] In rice processing and production, ensuring the purity and quality of rice is crucial. Iron impurities mixed in rice not only affect the taste and appearance of rice, but may also pose a potential threat to consumers' health. Therefore, effectively removing these impurities is an important link in the rice production process.

[0003] Rice is generally passed through a magnetic separator to remove iron impurities. However, after the magnetic separator absorbs the iron impurities from the rice, the impurities are magnetically adsorbed inside the magnetic separator, making it inconvenient to clean. As a result, the rice that subsequently enters the magnetic separator is easily discharged with some impurities, affecting the magnetic separation effect. Therefore, improvement is urgently needed.
