High-precision cooked wheaten food raw material processing device

The invention discloses a high-precision cooked wheaten food raw material processing device. The processing device comprises a machine body, an upper crushing cavity and a lower crushing cavity which communicate with each other are formed in the machine body, and a crushing assembly and a crushing and purifying assembly corresponding to the upper crushing cavity and the lower crushing cavity are arranged on the machine body. A driving shaft which is driven by a driving motor to rotate is arranged in the upper crushing cavity, and meanwhile, a pressurizing crushing block which is elastically supported by a strong spring is arranged in the upper crushing cavity; two crushing rollers are driven to synchronously rotate by the aid of a transmission crawler belt as well as a first gear and a second gear which are in meshing connection so as to further crush crushed materials entering the lower crushing cavity, then rotary motion of a strong wind wheel and a centrifugal sieve tray is realized by the aid of a third g
