[0043] Repeated screening using the first linear vibrating screen 9 and the second linear vibrating screen 10 can be used to screen out heavier impurities (heavier impurities are stones and grass seeds with a mass similar to flax seeds).

[0044] Workflow: Before screening the flax seed raw materials, close the first valve 18 and the second valve 12, and open all the equipment on the entire screening line. Then the raw flax seeds are transported to the seed hopper 1. Under the push of the screw conveyor 2, the raw flax seeds enter the first elevator 3. After the raw flax seeds are lifted to the highest level, they are discharged and enter the compound wind screen cleaner 4. Large impurities (grass stalks, sticks, large grass seeds) are screened out from the upper screen, and small impurities (sand, soil, small grass seeds, seed powder) are screened out from under the lower screen. Dust and turf are sucked away by the first centrifugal fan 16 and stored in the first cyclone dust collector 17. The first centrifugal fan 16 is emptied in the pulse dust collector 15. The flax seeds discharged from the middle of the two layers of screens enter the second elevator 5. After the flax seeds are lifted to the highest level, they are discharged and enter the specific gravity cleaner 6. The separation bin 61, the first separation plate 62 and the second separation plate 64 on the specific gravity cleaner 6 vibrate back and forth under the action of the transmission mechanism, and the layers are separated during the vibration. The heavier flax seeds and the heavier impurities fall on the lower layer of the material, and move upward along the vibration direction under the action of the vibration of the screen bed. The lighter flax seeds and the lighter impurities fall on the upper layer of the material and slide downward. After passing through the bottom surface of the separation bin 61, the impurities (shrunken seeds, husks) still existing in the primary screened flax seeds are sucked away by the second centrifugal fan 14 and stored in the second cyclone dust collector 13, and the second centrifugal fan 14 is emptied in the pulse dust collector 15. The flax seeds and the heavier impurities are discharged to the surface of the first separation plate 62 through the discharge port. After passing through the first separation plate 62, the lighter flax seeds slide back into the bottom hopper of the second elevator 5, and the heavier flax seeds and the heavier impurities are discharged to the upper right along the surface of the first separation plate 62 to the bed surface of the second separation plate 64. The lighter flax seeds slide back into the cleaning machine hopper 63 and are then pumped into the inertial dust collector 19 by the third fan 11, and then return to the bed surface of the first separation plate 62. The heavier flax seeds and heavier impurities enter the temporary storage hopper 7 from the surface of the second separation plate 64 along the upper right. The temporary storage hopper 7 releases the temporary flax seeds according to the actual screening speed, enters the first linear vibrating screen 9, and then enters the second linear vibrating screen 10 for repeated screening, only to screen out heavier impurities (heavier impurities are stones and grass seeds of similar quality to flax seeds). The first linear vibrating screen 9 and the second linear vibrating screen 10 are both double-layer linear vibrating screens. The finished flax seeds discharged from the discharge port of the second linear vibrating screen 10 are all mature, plump and regular. After the screening is completed, the flax seeds are bagged and stored.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
