AI Technical Summary
Existing water-based screening systems have limited accuracy in separating seeds and impurities of similar density, and they consume a lot of water and require cumbersome drying processes.
The system uses a vibrating motor and sieve plate to initially remove seeds that do not meet the requirements. Combined with the design of inclined plates and scooping nets, the seeds can flow to the next process. The system removes moisture through multi-stage filter discs and motor rotation, and uses a water pump to recover water resources, thus achieving multi-stage screening and water resource recycling.
It improves seed screening accuracy, reduces water consumption, simplifies seed drying, and enables efficient multi-stage screening and water reuse.
