新型介电式棉种分选机的设计与试验

Design and Experiment on the New Type Dielectric Separator of Cotton Seeds

简述了现有介电式分选机的结构特点,介绍了一种新型介电式棉种分选机。新机型减少了种子在分选滚筒上的跳动,使具有相同介电常数的种子受到基本相同的极化力,缩短了种子从过渡到稳定极化的时间。分选试验结果表明,新型棉种分选机能提高棉种的发芽率。

This article briefly states the present structure feature of dielectric separator, and introduces the structure character of a new type dielectric separator of cotton seeds. It can reduce the jump of seeds on the roll, and the cotton seeds, which have the same dielectric constant ,will hold the same polarization force. The time of transition to polarization is reduced. The new type separator machine can increase the cotton seeds germinate rate, which was proved by-experiment.
