Description

Technical Field

[0001] This invention belongs to the field of rice seed pelleting production technology, and specifically relates to a rice seed pelleting production device. Background Technology

[0002] In agricultural production, to improve and ensure the germination rate of crop seeds such as rice after sowing and to prevent the occurrence of diseases, coated seeds are often used. This involves wrapping the seeds with a film formed by a chemical agent to protect them from pathogens in the soil. At the same time, to facilitate mechanized sowing and provide nutrients for seed growth, seeds need to be pelleted. This involves coating the seeds with solid powder to make them basically the same in shape and size, while the powder provides the substances necessary for seed growth.

[0003] Patent CN210406139U discloses a pelleting device for small seeds, which specifically includes a seed storage silo, a solvent silo, a powder feeding silo, a pelleting coating mechanism, and a drying mechanism. After the seeds are sprayed or soaked in solvent, they are mixed with powder in the pelleting coating mechanism, so that the powder adheres to the seed surface, and finally dried to form the product.

[0004] However, the aforementioned pelleting device still has certain drawbacks. During the solvent spraying process, uneven coating occurs. To ensure effective coating, the patent further soaks the seeds in solvent, resulting in excessive solvent on the seed surface, which is detrimental to the pelleting operation. In other words, the solvent spraying operation of the seeds in the pelleting device of the aforementioned patent suffers from uneven solvent coating or excessive solvent. Summary of the Invention
