The invention provides a method for processing raw rice flour with low starch damage. The method comprises the following steps: (1) dipping: adding clean water in rice, dipping and draining water off; (2) grinding and sifting to obtain fine powder; and (3) drying: drying the fine powder obtained in step (2) at 50 to 60 DEG C, so as to enable the mass fraction of water in the rice flour to be controlled within the range of 8 to 10%. According to the method provided by the invention, a dipping method is used for processing broken rice by-products; by improving the formula and the process, the obtained raw rice flour is uniform in size distribution; the starch damage is lower than 5% and can be as low as 3.5%; based on saving of water resource compared with a wet method, the damage value of the obtained raw rice flour (powdery) starch is less than 1% in difference value compared with that of powder ground by the wet method and greater than 4% in the difference value compared with that of a dry method. Not only is the added value of broken rice products improved, but also the production performance of rice flour products is improved, and the quality stability of rear-end product development can be guaranteed.
