There are three types: rotary drum type, floating type and integrated type. Seed coating machine is composed of coating tank, batching, metering, spraying, air supply, power and transmission devices. Seeds and coating agent are repeatedly rubbed and squeezed against each other in the coating tank to form a coating layer with a certain strength on the surface of seeds. After being treated and coated by seed coating machine, the size and shape of seeds are consistent, which is conducive to mechanical sowing, improves sowing accuracy, and reduces seed consumption and thinning workload.

In addition, most of the existing coating machines are not equipped with a cleaning mechanism. When the later coating agent comes into contact with the external air, it will coagulate and adhere to the inside of the coating agent, affecting the quality of the later coating.
