It based on the different setting velocities of barley and
impurities, the washing machine can separate impurities including
Bingjian Stone in the similar size with barley. The de-stoning
procedure is omitted. therefore, the cost is reduced. The
environmental dust is controlled efficiently in the process of
de-impurity process so that the working environment is improved,
meanwhile, during the cleaning process the barley has received
water’s pre-soap which will contribute to the germination effect.
