Green walnut peeling machine adopts the peeling method of rotary-cut peeling. Once walnut conveyed into rotary cutting hob section, due to its high-speed cutting effect of hob, it can achieve effect of peeling off the green outer layer of walnut, during which process, walnuts rolling automatically in the chamber surrounded are cut by the hob in an all-round way with walnut of smaller size having not been peeled, after that, the peeled walnut continue rolling out from rotary cutting section automatically with a few unpeeled green walnuts are peeled and cleaned by surrounding wire brushes and semicircle brushes rotating rod mounted in the peeling chamber. Finally, the peeled clean walnut roll out from processing chamber to the container. After that, feed in new walnuts continuously with peeling and washing process effects achieved. The clearance between the grille and the rotary cutting hob can be adjusted automatically according to the size of varies walnuts and the thickness of the green peel manually adjusted by increasing or reducing the number of gaskets to reduce damage rate and improve the removing rate.

针对核桃加工中存在的问题和市场需求，核桃加工技术不断深化，除去皮、分级、清洗、脱水、干燥、去壳、仁壳分离、包装外，还进行深加工。对于传统加工来说，存在的主要问题是人工去核桃壳比较困难，无法满足市场对高品质产品的需求。因此迫切需要开发一种高效的全自动绿色核桃脱壳机。核桃分级机是核桃壳破碎机的必备设备。对于固定间隙的核桃破碎机，物料尺寸必须与固定间隙的尺寸相适应。现在核桃加工有：青核桃脱皮机；核桃破碎脱壳机、核桃烘干机、核桃筛分机等。
