A wheat concocting method comprises the following steps that S1, ozone and wheat wetting water are mixed through a jet device and then placed into a first intensive dampener storing wheat, and then the dampened wheat is placed into first wheat wetting bins to be subjected to primary wheat wetting; S2, the wheat passing through a wheat outlet of the at least one first wheat wetting bin is subjectedto wheat blending in a first wheat blending device and then subjected to secondary wheat wetting; and S3, the wheat passing through a wheat outlet of at least one wheat wetting bin is subjected to wheat blending in a second wheat blending device and then subjected to third-time wheat wetting, then concocting work is completed, and later operation is prepared to be conducted. The wheat concoctingmethod has the advantages that 1, the ozone is added into the wheat wetting water, so that the ozone effect is improved, brood bodies, spores, virus and the like can be killed, the water surface tension is increased, and the wheat wetting time is reduced; 2, temperature rising in a wheat stack can be effectively reduced through secondary wheat wetting; 3, through high temperature treatment of a steam generator, residual bacteria can be killed, and no large quantity of heat energy conduction endosperms exist; and 4, the ash content of the wheat is decreased by 0.04%, and the whiteness of wheatpowder is increased by 0.6.
