This utility model relates to an edible oil raw material screening device, belonging to the field of edible oil technology. It includes a vibrating screener with two fixed plates on its top. A screening cylinder is installed between the tops of each fixed plate. Bearing bodies are installed on opposite sides of the interior of each screening cylinder, and a rotating column is installed on opposite sides of each bearing body. The beneficial effect is that a speed-regulating motor drives a rotating rod and a second gear to rotate. This allows the second gear to drive the meshing first gear and the rotating column to rotate, thereby rotating a cylindrical magnet. The raw material flows through the discharge port on the screening cylinder onto the surface of the cylindrical magnet. The cylindrical magnet uses magnetism to adsorb iron products or other metallic foreign objects, thus completing the screening of iron products or other metallic foreign objects in the raw material. This method can meet the high standards of equipment protection and product quality requirements of modern edible oil processing.
