Embodiment 1
[0035] (1) Select high-quality and qualified fresh pomegranate seeds to remove impurities, moldy and deteriorated pomegranate seeds;
[0036] (2) Grind the screened pomegranate seeds with a machine to remove 15% of the epidermis to obtain the peeled pomegranate seeds;
[0037] (3) Sprinkle pure water evenly into the peeled pomegranate seeds, and adjust the moisture content of the pomegranate seeds to 10wt%;
[0038] (4) Put the moisture-adjusted pomegranate seeds into the preheated screw press for pressing, adjust the adjusting screw of the press, slowly adjust the thickness of the cake to 2-3mm, and start the cooling water cycle of the press to reduce the pressing temperature Control at 70°C to obtain crude oil;
[0039] (5) Add 1% diatomaceous earth accounting for the total weight of the crude oil to the crude oil, stir to disperse evenly in the crude oil, pump it into the plate and frame filter, and carry out circulating filtration until clarification, the filter pressure ...
