The invention discloses a soybean oil processing method. The soybean oil processing method comprises the following steps of an inspection process including that, before soybeans are put in storage, inspection personnel randomly sample three points from soybeans to be stored for spot inspection, then equally divide samples of every point into three and detect the humidity, saturation fullness and hardness of the soybeans through detecting instruments, and a collecting and screening process including that the inspection personnel purchase the soybeans inspected to be qualified. Through interaction of inspection, collection, screening, bin storage, fine screening, cleaning, drying, crushing, rolling, extruding and crude oil refining, the soybean oil processing method has the advantages of high soybean dust cleaning effects and high yield of crude oil, solves the problem that existing soybean oil processing methods are poor of soybean dust cleaning effects and low crude oil yield, and during oil processing, can avoid low crude oil quality due to impurities inside crude oil and improve the quality of soybean oil.
