5JDF-0.5型介电式种子分选机组及其性能试验

Experiment on 5JDF 0.5 Dielectric Seed Separating Unit

通过对种子清选原理的分析 ,论证了 5 JDF- 0 .5型介电式种子分选机组工艺流程的合理性 ,并利用该机组在不同的电极材料和不同的分选电压下对油菜种子和白菜种子进行了分选试验。结果表明 ,该机组不仅可按种子的千粒重而且可按种子的活力进行分级 ,并且通过调节分选电压可得到不同的分选效果。

The rationality of technological process for 5JDF 0.5 dielectric seed separating unit was demonstrated in this paper by means of analyzing seed cleaning and separating principle. Experiments of separating rape seed and Chinese cabbage seed were made by means of the unit under the conditions of different electrodes and different separating voltages. The results showed that seeds can be graded in terms of both 1000 grain weight and vigor by the unit, and different separating effects can be obtained by adjusting the separating voltages.
