Description

Technical Field

[0001] This utility model relates to the field of seed coating equipment technology, and more specifically to a seed pelleting machine. Background Technology

[0002] Seed coating technology is now widely used in industries such as breeding. It mainly involves coating small seeds with a coating agent to completely encapsulate the seed grains, making subsequent sowing easier. At the same time, the coating agent effectively protects the seedlings during planting and early seedling growth. The coating agent contains various drugs and nutrients needed in the early stages of seed development, ensuring germination rate and survival rate. Seed coating technology has made a significant contribution to seed survival and subsequent growth and development.

[0003] Traditional pelleting equipment generally suffers from the following problems: uneven coating, obvious defects in the finished pellets, weak coating layer adhesion, and easy peeling off during transportation or sowing; high seed breakage rate, often relying on rigid agitators to forcibly turn the seeds, resulting in a decrease in seed germination rate after processing, causing irreversible losses, especially for high-value breeding materials; poor metering accuracy and low degree of automation, making it particularly inefficient for processing small batches of multiple varieties of seeds; and a single method of supplying coating agents, making it difficult to achieve simultaneous and precise addition and mixing of multi-component coating agents.

[0004] Therefore, how to provide a new type of pelletizing equipment with optimized structure, high-efficiency mixing and low-loss processing capabilities, and excellent pellet quality is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
