The invention discloses a preparation method of semen persicae processed decoction piece formula granules. The preparation method of the semen persicae processed decoction piece formula granules comprises the steps that a, semen persicae processed decoction pieces are crushed or cut into coarse particles; b, the coarse particles are continuously input into extraction pipes of a continuous dynamiccountercurrent extraction machine, hot water is reversely and continuously added at the tail ends of the extraction pipes of each grade for continuous dynamic countercurrent extraction, and an extracting solution is collected; c, the extracting solution is filtered and subjected to superhigh temperature instantaneous sterilization, and filtrate is concentrated under reduced pressure to form a clear paste; d, excipients are added to the clear paste for dissolution, and spray drying is performed to obtain dry extract powder; and e, preparation excipients are added to the dry extract powder, anddry granulation is perform
