Separating the shell and kernel totally. It is very easy to operate it, just need to input the material from the first machine, and after the machine will come out shells and kernels respectively.

The specific gravity and suspended velocity between shells and kernels are different, the machine takes advantage of the feature, with the upward air flow through the particle clearance to facilitate the separation of kernels and crushed shells. Since the walnut kernel and shells have differ gravity, the large gap between shell and kernel, the separation effect will be better, the small gap, the effect is a little worse.
