The corn seed cleaning and grading line adopts a platform-based integrated design, featuring two parallel processing lines to significantly increase overall capacity. Each line consists of an air-screen gravity separator and a gravity grading machine, forming an efficient cleaning and separation system.The key advantage of the platform design lies in its ability to automatically collect and classify impurities. All waste materials are conveyed via a belt system installed beneath the platform and transported to designated impurity bins, ensuring organized and efficient handling.The entire production line is equipped with automatic feeding, automatic impurity collection, and an integrated dust removal system, effectively reducing dust pollution and improving the working environment.With high screening accuracy, high processing efficiency, and a high level of automation, this system is ideal for modern corn seed processing operations requiring consistent quality and performance.

To meet our customer’s processing capacity requirements, our company designed and installed two parallel corn seed cleaning and screening production lines.
Equipment Composition:
Each line consists of one air screen gravity cleaner, one positive pressure gravity separator, and a non-breaking bucket elevator. This configuration greatly improves the screening efficiency.
The air screen gravity cleaner effectively removes light impurities, large impurities, immature kernels, and moldy grains from the raw corn. The positive pressure gravity separator further eliminates moldy and insect-damaged kernels, ensuring that the purity of the corn seeds meets the required standards.
