1, natural drying of walnuts in the shade. Choose healthy, disease-free, pest-free walnuts with intact skin and put them in a ventilated place to dry naturally. After a few days, the walnut skin is wrinkled and shriveled, and the green peel will naturally separate from the walnut. But pay attention to the damaged walnut, the green skin will be partially black, so this method is not applicable, because it will cause cloudy skin. 2. Manually remove the walnut green peel. Need to prepare tools, rubber gloves, a small hammer, a knife, an iron brush, etc. First, use a small hammer to beat the walnut green peel, or use a knife to peel off the big green peel, then immerse the iron brush in water to continue scrubbing the remaining green peel, and finally carefully clean it with a fine needle and toothbrush. It is best to wear rubber gloves during the whole process, otherwise the skin on your hands will be dyed black.
3. Artificial ripening. Spray 200 times of "Ethephon" solution evenly on the green tangerine peel, and the green tangerine peel will separate automatically after a whole day.
4, rotten method. Cover the green walnut with straw mats, straws and the like, and let the fermented green peel rot and peel naturally.
5. Mechanical method. Use a special walnut green removal machine.
6. There are blisters on fresh walnuts, and it will be easy to cut them off after covering them for a few days. Or bury walnuts in the soil and peel them off. Keep walnuts in the shade for 4-6 days. When the green skin is wrinkled, put on rubber gloves and peel it off gently. The green skin of walnuts will fall off by itself.
Precautions:
Don't get the black liquid left on the skin on clothes and hands, otherwise the clothes will never be washed off and the hands will gradually fade.
