Seed Cleaning:
When seeds come out of the field, they may contain many types of particles (the desired seed, weed seed, plant material, etc.). In addition to the many different types of particles, the desired seed may have broken or other unviable seed mixed in to the lot. By removing these undesirable seeds and particles, you will improve the vigor and germination rate for your lot.
When removing the undesirable seed from your seed lot, there are many differences in the seed used to make separations.
1. Size (large vs. small and length, width, and thickness). The most popular way to separate particles of different sizes is by scalping (using a screen which allows the desired seed fall through the screen holes while removing the larger particles) or sifting (dropping out smaller particles by using a screen in which only the particles smaller than the seed are allowed to pass). Both of these separations can be made manually by using separating boxes or mechanically using devices like the Clipper Office Tester (see equipment section). Making length separations can be done by using an indented cylinder or disc machine.
