Technical Field

[0001] The utility model relates to the technical field of rice processing and stone removal, in particular to a vibration type rice processing cleaning and stone removal device. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling, and finishing. During the hulling process, rice is often mixed with broken husks and gravel.
