The invention discloses a simple peanut oil production process. The specific steps of the simple peanut oil production process are as follows: S1: Peanut material preparation, S2: Peanut screening treatment, S3: Water selection, S4: Drying treatment, S5: Shelling of peanuts, S6: manual screening of peanut kernels, S7: frying and peeling of peanuts, S8: crushing treatment, S9: compacting treatment, S10: oil pressing treatment of oil press, S11: purification and filtration of peanut oil . The invention strictly controls the water content in peanuts, realizes the oil yield of peanuts to the greatest extent, and at the same time, through multi-level screening, improves the quality of peanut raw materials for oil extraction to the greatest extent, reduces the incorporation of unqualified peanut kernels, and through water separation Double screening with artificial screening removes mildewed peanuts and shriveled peanuts, improves the oil yield of peanuts and the quality of peanut oil, making peanut oil healthier.
