Last week, my son, Nick and I toured Ball Seed Company's "Ball Premier Line" , seed prepping department.  Raw seed is graded and then placed in cyclones.  The cyclones allow the seed to fly through the air.  At the bottom of the cyclone are three spray nozzles that spray a special coating on the raw seed.

In photo, one raw seed has received the first coating. The second photo shows the seeds almost finished as they have received a yellow coating.  Ball coats seeds in order to make them slick.  Reducing drag on the seed allows growers to singulate the seed easier when running the seed through a seed sewing machine (you can view an earlier story on our in-house germination)

Pelletizing the seed makes the seed round.  Round, larger seed is easier to sew.
