1. The dust generated under hulling-work, not only ruins worker's health but also spoils mechanical function.
There upon, we devised, as its counter-measure, the dust elimination equipment that was manufactured in trial and then tested some experiments on it.
2. We observed the direction of air current in side same time measured the distribution of wind velocity within and without.
3. To show the effect of dust elimination, we temporally use the word dust elimination efficiency
η%=(q/Q)×100……(1)
Note: η……Duste limination efficiency
Q…The whole quantity of dust eliminated(g)
q…The quanty eliminated from all the dust generated(g)
4. By substituting the figures obtained of experiment in formule (1) we verified that its effect was great, the dust elimination efficiency representing 87.5% or an average.
