由於核桃的收穫期較為集中，且在收穫後季節較短，必須盡快去除外層綠色果皮，以保持核桃硬殼表面清潔，否則核桃仁會發霉，嚴重影響核桃的品質。內在品質，這裡有四種剝青核桃的方法。
手工剝皮的綠核桃
最原始的方法是用手剝皮，手動在皮帶上剝橡膠手套，並用石頭或刀剝皮。這種方法的缺點非常明顯，耗時長，不適合大量生產。少量核桃加工無法保證核桃外觀乾淨。在加工過程中，綠核桃皮的汁液也很難清洗，會弄髒雙手。
傳統的浸泡法剝綠核桃
傳統的堆肥法是及時將收集到的綠核桃運送到室外陰涼處，並根據50厘米的厚度堆放。如果堆積過厚，綠核桃容易腐爛，然後用10厘米的稻草和雜草覆蓋核桃堆。目的是提高核桃堆的溫度，加快核桃皮的脫落。經過4-6天的堆積，核桃皮會膨脹並裂開。此時，用木棒敲打核桃殼，幫助核桃皮脫落。核桃皮裂開並容易脫落。不能直接曝曬在陽光下的原因是曝曬容易導致變色，影響核桃品質。在堆積過程中，應注意避免核桃堆積產生的污水滲入殼內，降低核桃的商業價值。
乙烯醇剝皮
乙烯醇剝皮法是將新鮮採摘的果實用5‰的乙烯醇溶液浸泡0.5分鐘或用噴霧器噴灑。噴灑後，需將綠核桃堆疊50cm，保持在30℃，濕度保持在80%-90%，剝皮和沖洗應及時進行。通過此方法剝皮得到的一等果比例約為85%，產量較高。
機器剝核桃
該 green peeling walnut machine adopts free rotary cutting and peeling, the walnut enters the rotary cutting hob area, the high-speed hob starts to cut the green skin, and the walnut rolls freely at the same time so that all sides are cut by the hob. Continuously rolling out of the rotary cutting area, a small amount of unshaved green skin is cleaned by a wire brush and a semi-circular short-bristle brush cleaning rotary stick, and the clean walnuts are rolled out of the processing area and into the container. New walnuts are continuously fed, peeled and washed, and discharged. The distance between the grille and the rotary cutting hob can be adjusted automatically, and it can also be manually adjusted by adding or subtracting spacers according to the size of the walnut variety and the thickness of the green skin, so as to reduce the rate of shell breakage and improve the rate of net removal. Using machines to peel walnut green skin can improve the appearance quality and inner quality of walnut, reduce labor intensity and improve production efficiency. When the output is large, it is suitable to use the machine for processing, which can also shorten the processing time.
