[0024] The small package to be opened is placed at the bottom of the loading conveyor 1, and the loading conveyor 1 is started to transport the small package to be opened to the top of the loading conveyor 1, so that the small package to be opened is transferred from the top of the loading conveyor 1 to the inside of the feed port 4, and then to the inside of the package breaking mechanism 5 through the feed port 4, and is broken by the package breaking mechanism 5;

[0025] Secondly, after the bag is broken by the bag breaking mechanism 5, the broken mixture is guided by the guide plate 6 to the inside of the screening mechanism 2 for screening, and the screening mechanism 2 is rotated and rolled inside the shell 7, thereby driving the broken mixture to rotate, so that the grains reach the inside of the receiving hopper 8;

[0026] Then, the fan 9 is started to blow air through the inside of the air blowing channel 14 to the inside of the wind box 15, and the grains are screened twice, and the impurities are filtered by air separation. The grains after air separation will reach the discharge port 10, and then reach the bottom of the finished product conveying device 12 through the discharge port 10, and finally be conveyed out through the finished product conveying device 12. At the same time, the waste bag reaches the bottom end of the screening mechanism 2 and reaches the waste bag outlet 11 for discharge;
