NOVELTY - A grape seed oil is refined by sorting grape seed by wind power or manpower, crushing into crusher, softening crushed grape seed having moisture content of 12-15% into softening pot at 65-75 degrees C for 25-35 minutes, loading softened grape seed having moisture content of 8-10% into evaporating pan, frying for 18-30 minutes having oil temperature of 105-115 degrees C, uniformly heating, discharging fried grape seed having moisture content of 7-9%, uniformly pressing into round cake using pressing machine at 95-105 degrees C, immediately putting into pot, and pressing at maintained temperature of 32-37 degrees C.    USE - Refinement of grape seed oil (claimed).    ADVANTAGE - Process is environment-friendly, and product is naturally non-toxic and easy to absorb, does not contain cholesterol and sodium, regulates blood-fat, and contains unsaturated fatty acid and fat-soluble vitamins A, D, E and K.    DETAILED DESCRIPTION - A grape seed oil is refined by sorting grape seed by wind power or manpower, crushing into crusher, softening crushed grape seed having moisture content of 12-15% into softening pot at 65-75 degrees C for 25-35 minutes, loading softened grape seed having moisture content of 8-10% into evaporating pan, frying for 18-30 minutes having oil temperature of 105-115 degrees C, uniformly heating, discharging fried grape seed having moisture content of 7-9%, uniformly pressing into round cake using pressing machine at 95-105 degrees C, immediately putting into pot, pressing at maintained temperature of 32-37 degrees C, filtering, separating to obtain crude oil having temperature of 80-85 degrees C, heating crude oil into boiler, adding 0.5-0.7% saltwater and 15-20% oil at 50 degrees C, stirring at 75-85 degrees C, uniformly dispersing at 105-110 degrees C under oil bath condition until no blister, preheating at 30-35 degrees C, slowly adding 20-25% soda ash, stirring at 60-70 rpm, foaming, adding 20-22% sodium hydroxide, standing at 80 degrees C for 1-2 hours, spraying soft-water mist into surface of 10-15 wt.% oil, continuously stirring, washing for 1-5 times, mixing with decoloring agent to decolor, fully stirring at 80-95 degrees C for 30 minutes under atmospheric pressure, filtering or naturally sedimenting at 70 degrees C, deodorizing into deodorizing tank, indirectly heating at 100 degrees C, directly spraying into steam for 4-6 hours having vacuum degree of 800-1000 Pa, and adding antioxidant in which amount of steam is 40 kg/t of oil.
