Embodiment

[0013] The present invention is realized by the following technical scheme: a method for extracting oil from rice bran, which is characterized in that the method includes the following steps:

[0014] (1) Screening and frying: Use a 21-mesh sieve to remove the broken grains and impurities from the freshly ground rice bran, then put it in an iron pot and fry it, keep stirring, and the firepower should not be too strong to prevent coking, and fry until the rice bran When the temperature reaches 100-105°C (all turn yellow);

[0015] (2) Insulation and drying: Pour the hot rice bran after roasting into the basket surrounded by insulation, step on it, cover it and keep it warm for 2 hours, take it out, spread it thinly on the cement floor, and turn it frequently to dissipate heat. After the rice bran temperature drops to room temperature, it is ready for use;

[0016] (3) Moisture absorption and steaming bran: before oil extraction, spread the fried rice bran on the concrete floor...
