The large, medium and small seeds are classified into different sorting devices, and each kind of seeds is screened according to the different weights of the seeds. Taking the largest seeds as an example, the largest seeds enter the sorting device. The seeds with larger weight and more complete shape enter the large spiral blade 17 under the action of the centrifugal force due to the larger gravity, and flow out from the first discharge port below. The seeds with lighter weight and more flat shape enter the small spiral blade 18, and flow out from the second discharge port below. According to the above steps, the seeds are classified according to the size first, and then the classified seeds are screened according to the weight. The high-quality seeds are further screened, and the quality of the seeds is improved.
