The resurgence of peanuts is mainly due to the high water content, which exceeds the water content standard required for peanut storage.

Peanuts are not completely basked in the sun, or the storeroom is humid, and peanuts breathe vigorously. After storage for 5-7 days, moisture regain (or waterproofing) may occur. After drying again, put it in a ventilated and dry place so as not to regain moisture (pour water).
