[0002] Rice bran oil refers to the natural oil extracted and separated from rice through processes such as leaching or pressing. It is divided into two categories: rice bran oil and rice husk oil.

[0003] Filtration is a crucial step in the processing of rice bran oil. While a filtering device for rice bran oil processing (publication number CN221981719U) can achieve efficient oil filtration, its method for handling clogging is too simplistic. When clogging occurs due to excessive impurities in the rice bran oil, shaking the pull ring causes the filter screens to vibrate, dislodging the impurities. However, these impurities fall into the oil, affecting its cleanliness. Utility Model Content

[0004] To address the overly simplistic approach to handling filter clogging in existing technologies, this invention provides a filter device for pressing rice bran oil.
