| The separation of walnut shell and kernel in China mainly relies on manual separation, which induces the low productivity and ineffective guarantee of walnut kernel quality. In order to promote the efficient separation of walnut shell and kernel, the conventional separation methods were briefly introduced, the application of new color separation technology in walnut shell and kernel separation was emphatically discussed, and the application trend and research direction of color separation technology in walnut industry were prospected. The conventional methods of walnut shell and kernel separation mainly include magnetic separation, electrostatic separation and physical characteristics separation, but these conventional separation methods have poor separation effects. While, the purification rate of walnut kernel is above 99.6% by using the new technology of color separation. It can be seen that the new technology of color separation has a broad application prospect in the separation of walnut shell and kernel. |
