Magnetic separation specific gravity device for raisins

The utility model discloses a magnetic separation specific gravity device for raisins, which belongs to the technical field of food processing and comprises a collecting frame, a filter sieve is movably connected with an inner cavity of the collecting frame, a support is fixed on the back of the filter sieve, and a conveying frame is fixed on the top of the support. Raisin needing to be processed is conveyed upwards through the conveying frame, then the raisin naturally falls into the discharging frame, the raisin adhered together is separated through collision, entrained iron impurities are conveniently separated from the raisin, then the first rotating shaft is rotated to drive teeth to rotate, and the raisin is separated from the raisins. A baffle can be moved through a rack plate, the size of the caliber of the bottom of a discharging frame is adjusted, the raisin falling speed is controlled, then an electromagnet with adjustable magnetism is arranged on the lower portion, mixed scrap iron is attracted, i
