1: For natural shade drying of walnuts, choose healthy, disease-free, insect-free walnuts with intact skin, and place them in a ventilated place to dry naturally in the shade after being planted. After a few days, the skin of the walnut will become wrinkled and shriveled, and the green skin will naturally separate from the walnut. However, pay attention to damaged walnuts. The green skin will turn black in parts, so this method is not suitable because it will cause vaginal skin.

2: Manually remove the green peel of walnuts: You need to prepare tools, such as rubber gloves, small hammer, knife, iron brush, etc. Use a small hammer to gently tap the walnut green skin or use a knife to peel off large pieces of green skin first, then use an iron brush dipped in water to continue brushing the remaining residual green skin, and finally clean it carefully with a fine needle and a toothbrush. It is best to wear rubber gloves during the entire process, otherwise the skin on your hands will be stained black.
