The invention discloses a refining method of 
rice bran oil retaining oryzanol. The refining method comprises the steps of 1, conducting filter pressing 
impurity removal; 2, degumming with acid and alkali in sequence; 3, pre-decolorizing by using a small amount of activated clay, and then adding a large amount of activated clay under vacuum and high temperature for re-decolorizing; 4, performing low-temperature 
crystallization, 
filtration and dewaxing; 5, performing high-temperature steam stripping deacidification and deodorization; and 6, performing low-temperature low-speed stirring 
crystallization filter pressing 
degreasing. Filter pressing 
impurity removal equipment used in the first step comprises a 
machine frame component, a material pressing plate 
assembly, a pneumatic mechanism, a filter frame 
assembly and a material receiving trolley, the pneumatic mechanism is located on one side of the 
machine frame component, the filter frame 
assembly is located above the other side of the 
machine frame component, the material pressing plate assembly is located between the pneumatic mechanism and the filter frame assembly, and the material receiving trolley is oppositely arranged below the machine frame component. The problems that 
rice bran oil is large in acidity, and a large amount of oryzanol is decomposed and consumed in the refining process in the prior art are solved, and the nutritive value of the 
rice bran oil is increased.
