NX series of machines have following characters: The concentricity must not be adjusted, the belts are apt to be exchanged, the weight is much less than that of old model machines, it occupies much less area when it is installed and so on.

The machine can not only polishing rice, it can but also hulling many other grains such as soy bean, wheat, maize, pea, cowpea, sorghum and so on.

To compare with other model hullers, NX series of hullers increase the hulling functions and drop down the broken grains’ ratio in hulling processing.

To decrease the broken maize during maize degerming and de-endosperming, we improve the screen, frame in both of the shape and the size. We repalce original hexagon with current octqagon. Further more, we en-long the parts, too. Of course, current roller is more longer than original, too. All the improvements will increase the hulling functions and decrease the brokening functions.
