The seed pelleting process is a standardized method that transforms raw seeds into uniform pellets using specialized equipment. Its main purpose is to improve seed consistency, enhance sowing performance, and enable effective application of functional materials.
The process begins with seed pre-treatment, including screening, cleaning, and drying to ensure high-quality raw materials. The seeds are then fed into the pelleting machine, where a rotating system keeps them in continuous motion, creating uniform rolling conditions.
A liquid binder is first applied through a spraying system to provide initial adhesion on the seed surface. Coating powders are then added in stages, allowing materials to build up layer by layer. Through repeated cycles of spraying, powdering, and rolling, the pellets gradually grow in size and develop a uniform structure.
In the final stage, pellet size, surface smoothness, and uniformity are carefully controlled by adjusting rotation speed, spray volume, and feeding intervals. The finished pellets are then properly dried to stabilize their structure for storage and sowing.
Awell-controlled pelleting process depends not only on technology but also on equipment performance. Seed pelleting machines with precise control and stable operation can significantly improve product consistency, reduce material loss, and enhance overall processing efficiency.
