A plurality of first sieve holes 302 are provided in the middle of the sieve plate 301, and the first sieve holes 302 on both sides are overlapped with the first conveyor belt unit 1 and the second conveyor belt unit 2 respectively, and a blanking screen box 6 is also provided at the position of the lower side of the sieve plate 301 facing the first sieve holes 302. The blanking screen box 6 includes a box body 601, and a first flap 602 and a second flap 603 are arranged from top to bottom in the box body 601, and the first flap 602 and the second flap 603 are respectively tilted to one side of the ground, and a plurality of second sieve holes 613 are provided on the first flap 602. The first conveyor belt unit 1 and the second conveyor belt unit 2 have the same structure, and only differ in height, so that the overall production is more convenient and the cost is lower. The extension plates 303 on both sides are respectively overlapped on the conveyor belts of the first conveyor belt unit 1 and the second conveyor belt unit 2. A certain gap is maintained between the ends of the extension plates 303 and the conveyor belts to avoid interference when the conveyor belts rotate. The extension plates 303 on the upper side receive the popcorn from the second conveyor belt unit 2, and then pass through the sieve plate 301 and the first sieve hole 302 to complete the initial screening. The popcorn that has not been screened passes through the lower side. The extension plate 303 enters the first conveyor belt unit 1 and enters the subsequent process flow. The popcorn falling from the first sieve hole 302 is screened for the second time by the first flap 602 on the blanking screen box 6, so that the popcorn that has been fully popped but is relatively small in size can be collected to avoid the loss and waste of popcorn. At the same time, the smaller popcorn that has not been screened twice is recycled through the second flap 603. The first flap 602 and the second flap 603 are respectively arranged on both sides, which ensures the convenience of operation and also facilitates the staff to adjust the production rhythm in time according to the situation.

[0033] In the preferred solution, the scoring sieve frame 3 is supported on the ground by the adjusting frame 4, a plurality of guide posts 308 are provided in the circumferential direction at the lower part of the sieve plate 301, the adjusting frame 4 comprises a frame 401, a through slot 402 is provided in the middle of the frame 401, a plurality of third through holes 403 are provided on the outer side of the through slot 402, the guide posts 308 are provided in the third through holes 403, and a first vibrator 9 is detachably provided at the lower part of the sieve plate 301.
