In my opinion, you have to identify what is the seed in the working sample. Thereafter, you have to rub the seeds on a germitest paper because the seeds is separated from the flower structures that protect them. Next, determine the 100 seed weight. Thus you put a sample in the separator and slowly you must open the air outlet. At same time, you can verify how many empty structures of flowers and danified seeds are collected in upper part of the air separator. Please, let me know your results. I am writing and thinking about methods in plant breeding. Please see my paper on the researchgate about grass seeds. There you can access images of my work. I hope to hear from you soon. Best regards. Walter
There are several devices used to separate the seeds, and each device works differently. There are devices that depend in the separation process on the size of the seeds and others on the weight, and there are devices that depend on the color of the seeds or the shape of the seeds. As for the dynamic devices, it mostly depends on the size of the seeds.
