What are the standards for seed pelletizing?

Seed pelletizing is a new type of seed treatment technology. Due to its late start in China, an accurate evaluation standard has not yet been formed. Today, I will introduce to you the standards and items for evaluating seed pelletizing.

The first and foremost point is that it should be safe, environmentally friendly and degradable, have no adverse effects on the seeds themselves, and cause no pollution to the land.

The second point is that the shot powder should have a certain degree of fragmentation, generally ranging from 0.2 to 0.5 microns. The smaller the fineness, the tighter the shot produced will be and the higher the hardness.

Then, it must have a certain degree of hygroscopicity, that is, it can absorb moisture in a humid environment or when exposed to water. This not only ensures that the seeds are replenished with water but also enables rapid decomposition, which is conducive to the rapid germination of the seeds.

Another requirement is that it should have adhesive properties. This not only ensures that the powder can be evenly coated but also provides a certain strength to make the coating cohesive. Generally, the standard is between 600 and 1000mpa/s.

In addition, there are requirements for the shape, which should be round or nearly round, so as to reflect the significance of pelletizing. It should also have a certain compressive strength, that is, hardness. Generally, the compressive strength of a single seed should be above 0.5N.

The above are some common determination standards for seed pelletizing. Therefore, when conducting seed pelletizing, it is necessary to choose a professional manufacturer to do it.
