Study on the Rubber-roll rice huller. (5, 6)

On the effect of hulling capacity of Rubber-roll hulling part to admixture in paddy and the removal effect of dust elimination equipment

Abstract

1. In this experiment, the greater diameter of gum-roll is, the smaller the rate of hulling by admixture is.
2. The faster circuit speed of gum-roll is, the smaller the effect of fall of the rate of hulling by the admixture is.
3. The smaller a space of gum-roll is, the less the effect of the admixture of soya bean is, and the smaller the rate of fall of hulling is.
4. To pursue true character of growing dust to sting the worker's skin or his uncovered body.
To survey the removal effect of dust elimination using model hulling machine.
5. To find through microscope that Bown, chaff, Awn minute sand consists of dust-above all Bown (Pric home) are found very much.
6. Among the there forms of hulling machine, cool-absorb-eliminate equipment machine is most superior and abrorb equipment machine is less superior and no equipment machine is most inferior of them.
