1 heap compost peeling method: China's traditional walnut peeling method. The technical point is that the fruit harvested in a timely manner to the outdoor shade or indoor, avoid exposure to the sun, and then piled into a heap of about 50cm thickness (pile too thick perishable). If you add a layer of dry grass or dry leaves about 10cm thick on the fruit pile, you can increase the temperature inside the pile, promote fruit ripening, accelerate the speed of peeling. General composting 3 to 5 days, when the green fruit skin off the shell or cracked more than 50%, you can use a stick to knock off the skin. For those who have not peeled can be composted for several days until all peeled. Do not make the green skin black, or even rot when composting, so as not to contaminate the seed kernel with dirty liquid seeping into the shell, reducing the quality of nuts and commercial value.

2 agent peeling method (do not recommend this method): due to the composting peeling method peeling time is long, low efficiency, high rate of fruit contamination, the greater the impact on the quality of nut commodities, where, since the 1970s, some units began to try the vinyl ripening peeling technology, the specific practice is: after harvesting the fruits, in a concentration of 0.3% to 0.5% vinyl solution dipped in about half a minute! The specific method is: after harvesting the fruit in the concentration of 0.3% to 0.5% vinyl dip about half a minute in the solution, and then stacked in the shade or indoors at a thickness of about 50cm, at a temperature of 30 ℃, relative humidity of 80% to 95% of the conditions, after 5 days or so, the rate of peeling can be as high as 95% or more. 2 days or so can be peeled. Ethylene ripening time and the size of the concentration of drug and fruit maturity. Fruit maturity is high, the drug concentration is low, ripening period is also short.

3 Soaked in water and then covered for a few days, it is easy to cut off.

4 Artificial walnut green skin method: need to prepare tools, rubber gloves, small hammer, knife, iron brush and so on. Tap the walnut green skin with a small hammer or knife first large pieces of green skin off, and then use an iron brush dipped in water to continue to brush the remaining remnants of the green skin, and finally with a fine needle and a toothbrush to clean up carefully once again. It is best to wear rubber gloves throughout the process, otherwise the skin on your hands will be stained black. Note: Do not let the green skin of the juice splashed on the body of other skin, or not ulcerated, walnut green skin is also known as "green dragon clothes", its juice is very poisonous. Not to mention do not splash in the eyes. Artificial peeling green skin is the biggest advantage of the skin color is good, natural separation of walnut skin dark.

5 natural drying of walnuts, choose healthy, disease-free, pest-free, intact skin walnuts, down the tree into a ventilated place to dry naturally. A few days after the walnut's epidermis appeared wrinkled and dried, the green skin will be naturally separated from the walnut, but pay attention to the walnuts with injuries, the green skin will be blackened locally, so do not apply to this method, because it will result in yin skin.

6 artificial ripening. With 200 times liquid "ethylene glycol" solution evenly sprayed on the green skin, a full day later, the green skin will automatically separate.
