step 3, transferring the soybeans fried in the step 2 to a huller for hulling treatment;
step 4, placing the soybeans peeled in the step 3 into an oil press to be pressed at low temperature to obtain crude soybean oil;
and 5, precipitating the crude soybean oil obtained in the step 4, performing primary filtration by using a centrifugal machine, filtering peptization impurities, putting the filtered crude soybean oil into a freezing chamber, standing and precipitating for 30-50min at the indoor temperature of 1 ℃, putting the frozen oil into a high-speed freezing centrifugal machine with the rotating speed of 15000r/min, centrifuging for 15min, performing secondary filtration, and finally putting the oil into a vacuum box with the temperature of 60 ℃ and vacuumizing for 8h to obtain the soybean oil.
The present invention is also characterized in that,
in the step 1, drying is carried out until the water content is 5-8%.
In the step 2, moistening for 3-5min to make the water content of the raw material reach 9%,
in the step 2, the seed frying machine is baked and fried for 15-20min, the temperature of the seed frying machine is 120 ℃ and 140 ℃, so that the water content of the raw material is 1.0 percent;
in the step 3, the peeling treatment is carried out by separating peels and kernels by using a winnowing method, the peeling rate is more than or equal to 95 percent, and the kernel content in the peels is less than or equal to 1 percent;
in the step 4, the squeezing temperature of low-temperature squeezing is 50-70 ℃.
The invention has the beneficial effects that the roasted soybeans are added with water to uniformly absorb water, so that soybean protein absorbs water to expand and soften, the affinity between grease molecules and protein is reduced, the soybeans are favorable for squeezing out oil, and the squeezing performance of materials is improved, so that the oil yield is improved, the content of impurities in oil such as phospholipid and the like is greatly reduced, the complicated refining procedure of the squeezed oil is avoided, the process and equipment are simplified, fragrant substances in the oil are not lost, the fragrance is more concentrated and more lasting, the quality and quality of the soybean oil can be improved, the content of impurities is reduced, and the oil yield is improved.
