Experiment and Research on Awner of Vegetable Seed

On the basis of awn-removed principle that when spiral pushes seeds with awn forward along travelling device, there will be even rubbing among seeds, between spiral, machine shell and seeds, which can get rid of awn, this kind of awner of vegetable seed was made. In this way, it can avoid the damage done by machine elements directly touching seeds, and remove awn of smaller seeds. And it provides glossy seeds for further purifying and processing. By making a primary orthogonal regression test, the major factor and best parameter combination were found out, which supply theoretical basis for further research on awn-removed principle and awner. The plenty experiments by Laiyang Seed Company proved that the machine has the characteristics of simple structure, reliable function, high productive capacity and awn-removed rate.
