The invention discloses a screening and drying integrated screen for seed processing, which belongs to the technical field of seed processing. It can not only sieve the seeds, but also dry the seeds at the same time, which simplifies the process and improves the processing efficiency. It also has a special drying layer and a water-absorbing layer to dry the moisture on the surface of the seeds by direct moisture absorption. Compared with the hot air method, the activity of the seeds will not be affected by the high temperature. It is equipped with a water guide core, which can guide the moisture absorbed by the dry layer into the special expansion heating agent, so that the expansion heating agent expands and generates heat. It is also equipped with a water-conducting mesh rope set and a heat-conducting component. The water-conducting mesh rope set can assist the water-conducting core to conduct water. The heat-conducting component can conduct heat to the drying layer, accelerate the evaporation of water in the drying layer, and thus improve the drying efficiency. And the effect, and through the setting of inertial pressure components, etc., while effectively screening the seeds, the drying effect can be further improved.
