When passing through the shelling chamber 8 between the shelling rollers a9 and b7, the shells are crushed and fall onto the screen plate 6. The beans pass through the screen holes on the screen plate 6 and are discharged through the discharge port. The beans that do not pass through the screen plate 6 can enter the lifting plate 20 in the conveyor body 2. The lifting plate 20 is driven to rise by starting the telescopic rod 21. The beans on the lifting plate 20 enter the separator body 1 again through the discharge pipe 11 for secondary screening until all the beans are screened out.
