The invention relates to a production process of advanced woody blend oil. The production process comprises the following steps of: respectively carrying out virgin expelling on camellia seeds, tea seeds, Chinese torreya seeds, pine nuts, walnuts, hickory nuts, brook feather and plukenetia volubilis fruits under the conditions that the virgin expelling temperature is lower than 150 DEG C, and the oil outlet temperature is lower than 90 DEG C to obtain corresponding virgin oils and virgin slags, wherein the oil yield is 60-70 percent; putting the obtained corresponding secondary expelled slags into a supercritical carbon dioxide kettle, and carrying out extraction to obtain an extract with edible ethanol as an entrainer, wherein the additive amount of the entrainer is 5 percent of the material weight, and extraction is carried out under the conditions that the pressure is 35 MPa and the temperature is 40 DEG C; after filtering the extract, secondarily filtering the extract and removing impurities of the extract by active carbon, and carrying out vacuum removing on ethanol in a rotary evaporimeter under the conditions of 40 DEG C, 8kPa and 25 turns / min to refine the extract; and mixing the virgin oils to obtain a finished product. According to the production process, the camellia seeds, the tea seeds, the Chinese torreya seeds, the pine nuts, the walnuts, the hickory nuts, the brook feather and the plukenetia volubilis fruits are all woody oil seeds and even advanced woody oil seeds, the growth period of the woody oil seeds is long, nutrition is more accumulated, and the woody oil seeds have more nutritive value and functions than herbal oil seeds.
